Q: Network Connectivity Issues / Network Adapter Issues


Around 2 days ago the connection to internet on my computer suddenly failed. First I thought it was a router/modem issue, but I soon discovered this wasn't the case. I checked the ethernet cable, it's light was green and so was the router's light. I plugged the cable into my xbox, it worked completely fine.

So I started searching for clues on my computer, and after a while found out that all my network adapters have a yellow exclamation mark, and error code 31. This includes my main adapter:

Intel Pro 100/VE Network Connection

And all of my:

WAN Miniports

Searching the internet, I found some answers but they didn't work:

-I tried rebooting my router, entire network and computer
-I tried ipconfig /renew, it said that there wasn't anything available on my computer to perform that command
-I tried updating the drivers for my network adapters, but they said all my drivers are up-to-date
-I tried uninstalling/reinstalling the driver software, but it wouldn't do this
-I tired disabling Ipv6, but it wouldn't do this.
-I cleaned my entire computer with a registry cleaner and a Hard drive cleaner, scanned for spyware, malware, viruses and trojans. Nothing detected.

Can anyone help me? I would really appreciate it.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Hi and welcome to TSF please go to your computer makers support website for your model and update the driver from there, do not use the update driver feature in the device manager, or windows update as they do not always give you the most recent driver,if need be post the make and model of your computer here and someone will try to track down the driver

I reformatted my computer because after installing service pack 1 and other updates from Feb 14th my computer has been having issues getting a dhcp from my router. I have a windows 7 home premium 32 bit laptop that works just fine. I also have a ubuntu machine that pulls an address from this router and an xbox 360. From what I've read other places online it appears this is a bug with dhcp that appears some time around windows 7 service pack 1 x64. Is this update the one causing issues with the dhcp problems I'm having? Should I uninstall service pack 1 or reformat and not let windows install this? I'm a little confused as to what this problem is. Any help would be greatly appreciated! Thanks!

A:Dhcp issues and network connectivity issues since windows 7 x64 sp1

I've never heard of a service pack creating a DHCP problem.

You might want to try resetting your router either by pushing in the reset button "hold in for ten seconds" or you can reset the router from the router's service page or unplug the router for ten minutes then plug it back in again.

Just because other machines can pick up the DHCP address doesn't mean it's working correctly for all machines. Routers can limp along sometimes but the functionality becomes erratic until you reset them.

Or you can try using the ipconfig commands, such as the ones outlined in the link below.

My mother has a brand new Toshiba Satellite C55_B. It connected fine for a while to her home wireless network, but now it keeps having connection issues where pages won't load and things I try to download give error messages of not being able to download and check the internet connection. I've rebooted several times, ran the diagnostic thingy on the network adapter, the internet connection, and things like that, but it either comes back with not being able to diagnose, or it says it reset the adapter, or fixed something, but nothing really helps.

Any suggestions to try would be welcome. I'm only here at her house for tonight and I have to leave tomorrow, so if I can get this fixed tonight, that would be wonderful.......

Thanks for any help.

A:Network connectivity issues

What firewall or security suite is, or ever was, on the system?

Make sure it has the latest wireless driver from Toshiba's web site.

TCP/IP stack repair options for use with Vista through 10.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt. [For Windows 8 thru 10: <Windows Logo> + x - Command Prompt(Admin)]

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine after all three commands; no need to boot after the 1st and 2nd.

I am having some intermittent connectivity issues with my network and I have no idea where to start trouble shooting. It seems that from time to time (several times a day) people will lose there connection to the network momentarily. It only happens for a few seconds and there up and running. generally it doesn't cause any productivity loss, it's more of an annoyance.
But I'm afraid if I let it go on I will eventually have bigger problems. I used Ethereal to capture some packets, but I'm not sure how to read the output or what to look for. I have attached the Ethereal capture, if someone could give me a hand I would really appreciate it.

Thanks in advance,

On Monday evening I was skyping my girlfriend whilst playing xcom 2 when suddenly my Internet dropped. At first I assumed it was a housemates messing with the router however I then realised my phone was still connected to the WiFi and the Internet was fine on that.

Running windows network diagnostics claims that "one or more network protocols are missing" digging a little deeper it appeared to be pointing ne to winsock. So I then tried running "netsh winsock reset" which ran fine but didn't fix anything. I also ran "sfc /scannow" which yielded nothing. I've also tried using a system restore point and uninstalling avast antivirus with no effect. Finally I've also tried reinstalling "Internet protocol (TCP/IP) - Tunnel" but that fails with the error "This program is blocked by group policy"

I'm currently running Windows 10 (upgraded from 8.1) on a custom build rig. I'm happy to provide part names/specs ect if required.

Thanks in advance for any aid you can offer.

Lets take a peek at your network environment:


Power Cycle everything . . Turn off the Modem, router and all pc's . . turn on the Modem and wait a few minutes for the lights to stabilize . . then turn on the router, then one pc at a time. See if you connect to the internet.


Remove all the stored wireless network profiles and search for the network again.

I recently got a new HP Dv7 laptop, my old laptop was an older version dv7 and I had no issues and I did not change anything on my network. Here's my problem. I have to manually connect to the network 95% of the time, and it takes forever to connect, usually about 2mins, and sometimes I get the "it's taking longer than usual to connect" msg. It has always done this. I have tried updating driver, it says it's updated. I've unchecked the connect automatically, and even connect when not broadcasting, restarted and rechecked those boxes. But one thing I notice is every network available is checked to connect automatically and it won't uncheck those boxes, is that normal? I've never looked to notice that on other computers. And it's not just with my network, it's on all networks. Both the new and old laptop have been Win 7 64 bit, so I don't know why I'm having an issue with the new one. Could it be a bad network card? Thanks.

I have tried updating driver, it says it's updated.Click to expand...

Don't believe "it." Look for yourself. If an integrated adapter get the latest driver from HP's web site. If an external card get the driver from the card manufacturer's web site.

If you already have the latest driver reinstall it anyhow (in case the installed instance is corrupted).

In Network and Sharing Center - Manage wireless networks - remove any and all profiles.

Now try again and see if it is behaving.

I am trying to connect a PC to the network; the PC is running Windows XP Processional SP2.
It appears as the network signal is being received, the light is on at the back of the machine and the icon displayed in the notification area appears to be searching. But I can’t access the network or internet.
The PC doesn’t have an IP address, and can’t detect one automatically, when I try “ipconfig /renew” I get an interface error.
I have used XP TCP/IP Repair (http://www.softpedia.com/get/Tweak/Network-Tweak/XP-TCP-IP-Repair.shtml) to no avail

Another slight twist to the problem, I am working for an organization in China (www.chinaorphans.org) , so I am using the Chinese version of XP, which I can’t read!

Hey guys,nice to meet you.

I have some issues with my wireless network..this is no ordinary post, i'm not a complete roockie or anything. I had set up my internet connection perfectly, and it was working just fine for the past 1.5 years, until something really weird hapened.

One night, my laptop suddendly shutted down, and it restarted. After this, i just can't connect to my network. I also own another netbook wich runs on ubuntu and can connect just fine.

At first, i thought maybe some drivers broke down or something, and that's what they told me when i contacted my ISP, so i re-installed my intel proset wireless software and fully updated it, and now it runs perfectly, but i still cannot connect.
I also tried connecting my laptop to the router via the ethernet cable, and it does connect but it sees the network as "public" and cannot recognize it.

The most weird thing would be, that even though i partially connect to the router (with limited connectivity as it says)via the wireless, the icon on the bottom right of the screen does not change. It still has the "X" mark, as if i'm not connected anywhere. When i right click on it, it says "Connect to network" (if i was already connected it would say "disconnect)

I CLICK IT, and then ,by surprise i see that i'm already connected to my router with limited connectivity..how is this even possible :s.

Anyway, i also tried autoresovle, and all i get is that something is wrong with my ipv4 ipv6 ... Read more

Hi folks,

I'm new to the forum and would greatly appreciate some assistance. In a nutshell, I have a home network (at our small business) where one machine has most of the shared files and folders and connects to the one shared printer in the network (via USB). Everything was working fine until none of the other machines (3 machines total, all running XP) can connect to the network even though there's normal internet connectivity.

What's odd is that all the other machines CAN see each other and share files if I access them through RUN-\\computername but none of the other machines can access the network through My Network Places-Workgroups. When clicking on the network icon on the list, they all get "Network not accessible. You may not have permission to use this network resource...."

What's odd is that the main machine IS able to connect to the network and see all the other machines.

I tried re-installing the network on one of the other machines, but it didn't make a difference. I can't figure it out. Obviously now only the one computer can print, etc.

Any suggestions??? Thank you so much for being here!

I'm running Vista Home Premium SP2 (all the latest updates and drivers) x64 on a 2.2ghz amd dual core with 4 gb RAM. Recently I had a power surge hit my home and kill my built-in ethernet adapter (I have everything plugged into surge protectors ... EXCEPT the cable that runs to my cable modem, which was also fried). To my knowledge the nic in my laptop is solder to the motherboard, so replacing it would very costly. I decided to purchase an ASIX AX88772 Fast USB 2.0 to Ethernet Adapter. It works perfectly for 24-48 hours (my laptop is running 24/7). However, this is where the problem starts...

Seemingly randomly I will see that my network icon is now showing limited connectivity (even though my usb adapter is still flashing send/rec and my cable modem still has the PC light on ... however the cable modem is no longer flashing the send/rec leds). When I try to repair the connection it always fails. If I try to disable then enable the connection explorer.exe (process that manages network and sharing center) crashes (not responding and has to be killed and then rerun) even if I try this on a different connection (ie my old built in nic, or my wifi). Also, once this happens I am no longer able to connect to ANY networks (via wifi), windows will not locate ANY available wifi networks to connect to (even though there are over 8 in my area). Another baffling symptom is that if I try to shut down/restart/Log off it sits at the restart/shut down/log off screen and never actually com... Read more

I have one PC hardwired on the network at home that frequently loses connection and has to be manhandled before I can eventually get it to reconnect. If I run the troubleshooting wizard, when it goes to reset the network adapter, afterward it will claim no Ethernet cable is connected until I remove and replace the cable despite being properly connected prior to that. This is a frequent enough issue that there's no promising YouTube will work long enough to watch a video of any significant length. I could really use advice on this one.

Hi All,
This is my first post here. We have a major problem with my wife's Acer Timeline laptop. I believe the problem may have occurred after an iTunes update. I tried restoring back to earlier dates, tried uninstalling network adapters and rebooting, all with no success. Device manager originally showed issues with ISATAP #3, Teredo Tunneling, ISATAP #2, 6to4 and Miniport IKEv2 adapters. I was able to delete (uninstall) them all except the IKEv2 and when I reboot, IKEv2 still shows up as an issue with a yellow exclamation mark.
The machine has lost all connectivity, ethernet and wireless. It also is not able to print via the USB printer. I've been searching all over and cannot find a solution. I'm running AVG free and have disabled that also, also disabled the firewall. I have confirmed that the agilevpn.sys has not been infected by a virus, but I'm thinking it could be corrupted.
In the hidden devices, there are issues with HTTP, Qos Pack Scheduler, Remote Access IPv6 ARP Driver, WFP Lightweight Filter and Windows Firewall Authorization Driver.
At last resort I will reinstall the OS, but this laptop didn't come with a recovery disk and I'm not sure if I created one, can't find one anyway.
I'm not sure where to turn next.
Any help would be appreciated.

A:Laptop Network Connectivity Issues

Okay this might be stupid but there is like 3 different ways a wireless card can be turned off. Maybe more. First there is the physical button outside the case. Then, there might be a "Fn" (Function key on the keyboard) + "<wireless icon> " button on the keyboard. You might have multiple wireless connection managers installed, and any one of them could have the ability to switch off your wireless connection. And sometimes it's called "radio", btw... The adapter could be disabled in "network connections" or in "hardware manager" also.

And those are the easy to fix possibilities. There's TCP/IP Stack corruption (which I have no idea what that is, but read about it all the time), your firewall could be turned on and not allowing connections.

Guess the first thing to do is check hardware manager, click "show hidden devices" and report any flagged items here. Uninstall all flagged items and see if the O/S finds them on reboot.

My wireless connection kept dropping out today so I decided to try using a different wireless router to see if it would help. I tried using a Linksys router with dd-wrt on it and could get it to work so I decided to put the old on back on. Now it won't work at all.

The main desktop is connected via Ethernet cable through the wireless router and worked this morning. Now after I messed with it, it does not work at all. I have to go directly from the modem to the computer to get it to work

Our internet is a high speed tech that broadcasts from a tower to a receiver on our house and then through a coaxial cable to our modem. (not sure what they call it)

Attached are pictures of the network diagnostic message and ipcongif/all results for the desktop and laptop.

I tried to mess with the DNS settings to get them to an "open source" I believe.
It was advice from another thread on this forum but I couldn't get any of it to work.

I've been working on this for hours today and I am at my wits end!! any help would be immensely appreciated.\

Thank you.

A:Network Connectivity Issues!!! AAARRGHHH

Many times you have to power cycle (unplug for 30 seconds) the modem when switching the device connected to it.

You have an apparently good connection to the router so look at its WAN (Internet) status to see if it got a good IP configuration from the ISP.

Hi All,

Though I frequent these forums, this is my first post. I appreciate the helpful community here.

So I am a t1 Tech for a small company that primarily does multimedia/design etc. They just started branching into IT managing/support services and hired me to see if it's an avenue they want to stick with. I'm still in school for Network Admin and am by no means an almighty tech guru (but hope to be one day).

A:Frequent wireless network connectivity issues

Hello, I hope everyone is having a great morning so far.

I am posting because I am having some internet connectivity issues in a medium sized network that I am responsible for (about 40 computers total). I would consider my own networking skills as intermediate, so your help would be greatly appreciated!

First off, here is the setup:
This is a non-profit after-school program with 40 total internet connected devices. The internet service is AT&T DSL with 6Mb download (and I think 1Mb upload).
For the modem/router we have a 2Wire2701HG-B (with wireless disabled),

The 2wire then runs to the sonicwall NSA 240,

The sonicwall then runs to (2) Linksys SRW224G4 network switches.

Then the network switches of course run to all the computers in the building and to one wireless N router. We have the wireless disabled on the 2wire because it is before the sonicwall and devices connected to it would not have the protection that we require.

The problem is when all the students get on the computer, not all of the computers have internet access. Internet explorer gives the cannot display webpage. When I click on "Diagnose Problem" sometimes it can't find an error and sometimes it gives the DNS error.

This problem is not limited to any specific computer, it is all the computers at one time or another. Some are able to browse and some are not (pretty much "first come, first serve" for the internet connection).

If any one has any ideas on how I could impro... Read more

Hello, I've been having a few issues with my HP Pavilion dv6000 that I received from a friend.The first issue is that certain programs that would normally run on this computer when I first did the system restore won't run anymore. I try to re-install it but even the setup program doesn't even load. The one time that one does load is for Google Drive and it sends me to an error message. I do have images of the error message including computer information should it be needed. The second issue is that we just received the new Xfinity router/modem unit which I believe is an Atheros model with WEP2 AES coding and even though this laptop connects to my neighbors Netgear without issue, it will not sync to the Atheros at all. What I do end up with is thirty minutes of network identification only for the IPv4 to only read local while the IPv6 reads limited. I have tried turning the internet router off and nothing happens however I have the ipconfig/all information on a separate screen cap. I hope that this is enough information and though I have all the information in two screen captures, I don't feel 100% comfortable sharing this information over the forums just like that.

I really appreciate the awesome people here at bleepingcomputer. I am at wits end with the constant BSOD'S. All my issues seem to stem from a few days in December after my computer automatically installed a few MS updates, an Adobe update and an AMD driver update all basically on the same day. I noticed unusual behavior in early January. A strange Apple update on my Dell on my birthday, then BSOD's after updated drivers. Blue screen crashes with updating Windows Defender virus definitions and MS updates were failing a lot. That was just the beginning...Over and over, I tried to update the driver, or just let my default driver run, nothing worked. I disabled automatic update and install as that was not working and disabled Defender and Malwarebytes as both caused crashs in the past few months and I am beginning to hate them, after seeing 20 or so since Christmas. I googled the situation for a few months and found a few topics related to 4 or 5 of my issues concerning " a patch for a patch to a patch" KB3004394

Hi, I've been having issues with my network adapter that I put into a custom built PC. It worked fine for a while until I started messing with some drivers. I've reinstalled every driver possible and checked to make sure there is power running to the adapter. When I plug a Ethernet chord into the adapter the computer does not detect it. As if nothing was plugged in. I have checked this chord and it works fine with other PC's. There is a yellow light that keeps blinking where the Ethernet cable goes, I'm not sure what that means. I just reinstalled Windows 7 in hopes of taking care of any driver issues and everything is working fine besides that. I feel like it could possibly be a BIOS issue or a driver issue but I'm not sure how to approach that. Any help would be great thanks.

After installation and system reset the driver & device appear but won't work.

I looked at the the adapter in device manager and there's a yellow triangle near it. I check the properties and it say's "This device cannot start. (Code 10)". Not sure why it's there even after I installed the latest driver.

So then I uninstall it and DL the 2011 driver from the driver company "Realtek" repeat the above steps and I get the same problem.

Which adapter model is it?

I?ve been having problems with my network adapter. Whenever I start up my computer, I have to manually activate it via the Network Connections control panel. I?m able to connect to a network for about 5-10 minutes before an error symbol appears above my connections menu. When I open it, it shows my previously connected WiFi service, and none of the others that are usually shown. It tells me I have no internet connection, which is quite obvious. Disconnecting causes the list to blank. I?ve tried to run the network adapter troubleshooter, but it detects no problems. I can?t even connect to the internet without restarting my computer. Please help.

A:PS2 Network Adapter Issues!

Are you using a router with your PS/2 and your PC you used to get this screen shot?

I looks like you have the PC directly connected to the modem and if your just doing a switch I.E. Pulling out the plug and then putting it in the PS2 you have to reset the modem each time.

I would suggest using a router so your not having to switch back and fourth. Also probably want to move this to networking.

I downgraded my system to windows 7 32bit. It initially came with the windows 8.1. Ever since then I had been unable to fix my wireless adapter...even tried driving it with driver talent. It always comes up with: "The requested device registry key does not exist".The name of the adapter is Broadcom BCM43142 802.11 bgn Wi-Fi Adpter. please help...I'm fed up

A:Network Adapter Issues

The wound is entirely self-inflicted. Why 32 bit? Just makes it harder to find drivers.  Once you have used something like DriverTalent you are frankly best off wiping and reloading. Do you maybe have a copy of 64 bit Windows 7? Did you make the HP Recovery disks?  This is the HP driver for your Broadcom adapter and supports 32 bit Windows 7. If this does not work something else is going on and I will point the finger at DriverTalent.  http://h20564.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_133353_1#tab3

Okay, I had a malware program and searched the internet for a quick-fix and found Combofix.
When I ran it I thought I was disconnected from the internet and I wasn't, luckily it was just wireless so the hardline still works.

Okay so I checked my hardware and there is a yellow ! next to my network adapter. I reset the WINSOCK entries, IPv4 TCP/IP stack, and IPv6 TCP/IP stack, with no improvement. I'm using XP.

I also downloaded the latest driver for my Wireless utility "Belkin Wireless" to no improvement.

Help me out or send me a link to a similar thread, this cable running through my hallway is a real eyesore.

Hi, I'm Ben, a newbie at the forum. Please could you help me with my problem as it's doing my head in!
I've attached the info file about my system. I wish to use a wired network as wifi is poor in my house and the PC is a way from the router.
These are the symptoms:
1. No internet at the browser, or a warning triangle on the network indicator in the system tray. Sometimes no warning triangle and network and sharing centre indicates connection to the internet, but still nothing possible at the browser.
2. Logging in as admin and reinstalling the (same) network adapter drivers fixes the problem, usually until next boot, but this is not entirely predictable. Sometimes it fails at resume from hibernation (I think).
3. The problem is present whether I plug into the router direct or via a Homeplug network (which has worked fine with my laptop)

Things I've done to figure out where the problem is:
1. Connected my other PC (laptop) to the same wire. No problems. Also have internet access at my TV, it's fine, so I surmise there is a PC problem.
2. Various browsers, settings, troubleshooters, reboots of router, PC etc.
3. Fitted a new network card and latest drivers to exclude MoBo ethernet adaptor problems. Disabled the MoBo ethernet.
4. Reinstalled windows (today) with fresh 32 bit install. I was previously using 64 bit and wondered if this might be a factor.
5. Contacted my ISP for help - they couldn't find a fault.
6. Plugged in a wireless dongle - internet worked. Don... Read more

Hi! I'm having a few issues with my computer hopefully someone can help me.
Here's my specs 
Anyways, Recently. I had noticed some issues via my network adapter (so I thought) it would randomly change my network connectivity to limited when downloading or gaming.
So I decided to purchase a new wireless adapter. I installed the drivers via the CD and I had also updated them from the official website,
I tried to download some files. And after a while my network connectivity had changed to limited once again. I also noticed, that when I disable my network adapter.
I cannot re-enable it. It get's stuck on the "Enabling" screen. I also noticed that my network speed randomly drops (It's only for me, I had tested it on other computers) I had also formatted my PC a few times. Could it be my motherboard?

WiFi is not, and cannot be dependable. Wikipedia: WiFi > InterferenceInterferenceFor more details on this topic, see Electromagnetic interference at 2.4 GHz.Wi-Fi connections can be disrupted or the internet speed lowered by having other devices in the same area. Many 2.4 GHz 802.11b and 802.11g access-points default to the same channel on initial startup, contributing to congestion on certain channels. Wi-Fi pollution, or an excessive number of access points in the area, especially on the neighboring channel, can prevent access and interfere with other devices' use of other access points, caused by overlapping channels in the 802.11g/b spectrum, as well as with decreased signal-to-noise ratio (SNR) between access points. This can become a problem in high-density areas, such as large apartment complexes or office buildings with many Wi-Fi access points.Additionally, other devices use the 2.4 GHz band: microwave ovens, ISM band devices, security cameras, ZigBee devices, Bluetooth devices, video senders, cordless phones, baby monitors, and (in some countries) Amateur radio all of which can cause significant additional interference. It is also an issue when municipalities or other large entities (such as universities) seek to provide large area coverage.Even bad electrical connections can cause broad RF spectrum emissions.

I have Windows 7 Pro installed. I also have an A-DSL connection which goes through a router, and it requires a username and a password. Everything was working fine until today. My LAN connection is in the Home Group, and the other connection that I used to dial with was also in the same group, but today, for some reason, it wont show in the home group. I can get online with this connection, but it has slowed down considerably. When I ran a diagnostic, it said that I need to reset my modem. I did that, and i also reset the router, but this has not changed anything. I ran the diagnostic again, but it could not find the problem this time.

There is also a 'caution symbol' on the network icon in the tray and all it says is 'Network - No internet access'. Below that is the other connection through which i dial with the username and password. My connection is named M 1, and earlier, when I hover the pointer over the network tray icon, it used to show 'Network - No internet access' and 'M 1 - Internet access'. Not anymore.

The network diagram that shows how the computer connects to the internet has also changed, and now shows that I am connected to 'Network', but there is no connection to the internet from there. This is different from before.

Any ideas whats wrong? Other computers using the same router have no problems.

Looking for some insight into whether I need a new wireless adapter or if this is a windows 10 issue.  The Pavilion laptop I have is loosing wireless connectivity due to a locked up wireless adapter (Ralink RT3290). When this happens, I cannot physically turn off the adapter using the key ie. it stays blue regardless how many times pressed, but will switch to Airplane mode.  When this happens, the Network Centre does not show a wireless adapter or any networks.  I have been able to get this back on line with a hard reset, but it eventually locks-up gain.   The computer is slow to boot and ocassionally freezes even when wireless card seems functional.  When it freezes there is no mouse activity and I cannot start the Task Manager. Sometimes I regain function and sometimes it restarts.  Any help is appreciated.

My Dell Vostro 13 running on Windows 7 home premium started showing 'limited access' wireless connectivity issues. Network diagnostics suggested a problem with drivers for both the wireless network and LAC adapters. I updated the wireless minicard (with v5.50.18.8) and also tried running in the safe mode (I think I lost the connectivity after the latest Windows Update) but I still can't connect to the internet through any of the connections (wired and wireless, at work and home).

First and foremost I would like to apologize if this threat title is not good format.
I have recently just installed a Windows 8 OS on my PC, as previously I had assistance with building it from my Uncle which had installed an illegal version of windows 8.1 on it, which did not make me comfortable in the least. I digress.
Since the purchase of the legal form of Windows 8 (64 bit to be a bit more exact) I have noticed an initial issue with the computer not being able to connect to the internet what so ever, and I have it connected directly via an Ethernet cord as this is a desktop with no Wifi capabilities as I am not wishing to purchase anything for it to be Wifi.

I did a quick few routine troubleshoots as I figured it may have just been a minor issue, but quickly I saw what might very well be the route of my problems as I have gotten the message in exact words "Windows did not detect a properly installed network adapter. If you have a network adapter, you will need to re-install the driver."

From there I clicked next (Being that the Windows Network Diagnostics page was open) and from there I have the "Problems Found" telling me that "Windows could not find a driver for your network adapter."
A few of the websites I have checked asked for specific makes and models of computers, so if it is an actual necessity as this is not a simple dell, or toshiba computer, please ask if you need to know the specs of my computer. Any and all help is great... Read more

So it's a PC you built. If so then what is the make and full model number of the system board or if you have a discreet LAN card what is it's make and model number.

Sounds like all you need is to download the right driver and you should be set.

My network adapter, an Intel Wireless Wi-Fi Link 4965AGN, is behaving very strangely. In fact, ever since I got my new laptop, it has been acting weird. Half of the time it connects to the router my roommates and I have set up just fine, albeit after changing the connection settings around a bit. The connection is stable with no problems and it is very fast. However, the other half of the time, it will just simply not connect to the network, no matter what I do. I've tried many things to fix it, but ultimately I just have to wait until the adapter decides to figure out that there's a network connection. Some things that have worked for me in the past were disabling and re-enabling the adapter, re-typing in the network password, and activating the Wi-Fi scanner on the side of the laptop for a brief period of time. However, none of these are consistent fixes, which troubles me. About every day, the internet just stops working, and then magically works at the most random times after I do the most random things. I mean, at least it's working, but the trouble is: what if I need to use the internet right away to submit a paper or something? Plus, I shouldn't just settle for hardware that works only half of the time.

So my question is, has anyone had a similar problem or can anyone point out something I may be missing? I'd really like to get this adapter working full time. Any help on this would be appreciated. Thanks!

Ok I have the Dlink Rangebooster N router and notebook card from Newegg recently. I have the router up and running perfectly. I have a laptop with internal wireless connecting at 270 but I have another desktop I built using a Rosewill PCMCIA adapter to use the N notebook adapter on the new computer. Problem is that the new computer is only connecting at 54 which is G speeds. Is there some sort of setting on the notebook card somewhere that tells it to use g or n? Right now the router is using WPA-TPIK (pardon if wrong arrangement of letters) and is mixed g and n. I set it to N only and the new desktop will not even recognize the router so something is up with the notebook adapter or maybe the PCMCIA adapter will only allow g speeds.

Local connection works on the desktop but I need it to be wireless as well.

All my USB slots have been installed correctly and other devices function in them such as mouse, keyboard, etc. I can't use a pci wireless card because my gpu fan is blocking the pci slot. I am thinking it is probably a software issue.

I have been having real issues with the computer locking up for several week.  It looked like a driver issue, but all the updates and 4 fresh Windows installs in the last 4 week failed to help.  It would typically freeze 3 or 4 times per hour and alt-ctl-delete could not save it. Some observations:- sometimes if I watched the wifi indicator I noticed just before a crash that the signal was lost.  If I rushed to device manager, I could disable the adapter and re-enable so the crash was prevented.- sometimes the device manager said there was no driver installed for this device, yet I was on wifi only moments before. Ready to throw the computer in the trash, but then I saw my old HP laptop which overheated 'til it died.  I stole the wifi adapter out of it and swapped out the Realtek.  The old Qualcomm Atheros AR8295 adapter is working like a charm...3 solid days without a freeze, but I no longer have Bluetooth.  The only puzzling thing is that the old computer had 2 wire leads to the adapter, while this p168ca has only 1 wire. Did I find the real issue?  How do I get a new replacement adapter?  Is there a better "upgrade" adapter?

A:Realtek RTL8723BE Network Adapter Issues

Hi: I would agree with you that the wifi card is the root cause of your dilemma. HP has this nasty habit of only installing one antenna on notebooks with single band wlan cards, so your only other option would be to get another card with only one terminal. Upgrading to a dual band card is a no-go unless you are willing to take the whole notebook apart including the display panel area to run a 2nd antenna. Now, is the Realtek bluetooth card bad, or does it just have a problem with W10? Therein lies the question.
