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.)

I recently purchased a new laptop running Windows 7.  On setup, I was pleased to find that it connected to my home network without much complaint.  However, I soon noticed a misstep -- after putting my laptop to sleep, upon waking, it
would consistently fail to connect to network.
I've tried disabling IP Helper, as well as the wireless adapter's IPv6 protocola
la advice on other forums.  I've also ensured that the driver settings do not allow for disabling to save power.  Seeing that none of these worked, I decided uninstall and delete the driver and install a newer version (in a related issue,
the driver update feature failed to detect the existence of a newer version -- why?).
This appears to have fixed the connection issue.  However, still, after sleeping the laptop and waking, although it connects to the router, I still need to reset the IP command-line via ipconfig /release + /renew.
I was running Vista on my previous machine, and I know that its Network Diagnostic tool would, when presenting solutions, frequently suggest that my computer had the wrong IP and that I should reset it.  I was hoping throughout this process
that the Network Diagnostic troubleshooter would present a similar option.  Instead, however, no matter what I do with my wireless, the troubleshooter only ever returns the message "Troubleshooter couldn't identify any problems."  Whether or not
I check the box for auto-repair or run ... Read more

A:Troubleshooting the Network Troubleshooting Utility / After-Sleep Connection Problems

To avoid confusion Let us focus on the first issue within this thread first.
Can you access internet when connecting the laptop directly via cable?
Where did you download the newer version of network card driver? Usually, the “driver update” feature from device manager will go to Microsoft update catalog website for the corresponding driver instead of the manufacture’s website. AT
this point, I would suggest install the latest driver
here. Please note: Microsoft don't write drivers, for any driver related issue, the OEM is always the best resource to turn to. Your understanding is appreciated.
As a workaround, you can prevent the network card from sleeping by the following method:
Open Device manager->expand Network adapter-> right click on the wireless adapter->Properties->under Power Management tab, uncheck the box before “Allow the computer to turn off this device to save power”.
Is anything unclear, please feel free to post back.

I have been trying to see the contents of a FLOPPY disk that I created a few weeks ago at the library when my PC was out of commision. I made a BOOT DISK from bootdisk.com and wanted to explore it on my PC but for whatever reason, I cannot explore and see what's on the floppy.

The little green light comes on by the "A" drive (FLOPPY) yet I get the attached error messages.

How can I tell whether or not this problem is with the DRIVE or this particular floppy? This is the only one I have and I wanted to create a boot disk for my computer by erasing whatever was on this floppy and then creating a boot disk.

Thanks in advance

For quite a while, I have faced a black screen when booting Vista. BIOS runs nicely and Vista starts loading but stops dead with black screen just prior to login screen. After turning power off and restarting, I get the option to run a startup repair or boot normally. As I have a OEM pre-SP1 restore partition, I always choose normal start and this time Vista starts nicely. Guess I have a driver issue. Otherwice computer runs nicely.

I thought this was related to a faulty memory stick, but as this has been replaced, and the error persist, I guess it is something else. Will run more memory tests tomorrow, and will try to update graphics driver.

The problem does not appear in the event log and I do not get any error message. Anyone have a suggestion, how to troubleshoot this, whithout going through the trial and error process of installing drivers for just about everything, as this could just as well cause more problems than it solves?

Hello everyone,

My parents have COMCAST internet. I am connected to a home private network by wireless modem that we have with the service. I close my laptop at night to put it in sleep mode. Then, I bring it out of sleep mode the next day. When I do, I am no longer able to connect to the home private network even during troubleshooting scan resolve; no internet connection at all. The home private network name we have is listed in the wireless connections side menue, but it says can't connect when I try to click on it to connect. I open network and sharing center and I noticed that I have Local area Connection, Local Area connection 2 and Local Area Connection 3 listed and says unidentified network for each one. My home private network no longer shows in network and sharing center.

Hey guys, I have some trouble with my home network and I'm running out of ideas. I don't like to ask for help but here I am, a little desperate as well to be honest.

The network components:

Switch (10 clients, 1 server (Windows Server 2008 R2 with AD/DNS/DHCP), 1 router)

Now I bought a new Router (ASUS AC66U) for the second floor, which I configured as Accesspoint so I can use WLAN, also connected to the switch.

I flashed DD-WRT and everything seemed to work fine, but sporadically I lose Internet connectivity on my WLAN connected devices. Later I discovered, that I also lose connection on my clients when that happens.

I ran a wireshark capture on one of the clients and what happens now (reproducible) is that when I open a URL I get lots of TCP DUP ACK and TCP RETRANSMISSION packets, the site opens very slowly, if at all. Now the interesting part: When I turn off the AC66U and open up a site it instantly loads and there are maybe 1-2 retransmission packets.

I didn't run the wireshark trace on other firmwares I tried (ASUSWRT Merlin, stock firmware and TomatoUSB by Shibby) but the symptoms are the same.

In the source of the packets I see the MAC adress of the first router, which connects to my ISP and I guess there is some kind of conflict but I am by no means an expert to network related stuff.

I would greatly appreciate it if someone could guide me through the setup of DD-WRT to coexist peacefully with the other router or give me some useful hints on h... Read more

Hi all, I really don't know squat about networks, frankly I am surprised that I got it working and kept it working for a couple of years now. Recently the teens got their own systems and everything ran smooth for a few weeks and now we constantly get internet outages.
We have a win xp machine that is home to the cable modem and a belkin router, model
f5d7230-4, a windows 98se machine with a belkin usb adaptor, another win xp also with a belkin wireless usb adaptor and a Linux machine with a d-link card. ( I'll have to hunt up the exact model) The problem is that we are constantly loosing internet on the second xp machine and the linux machine ( the win 98 machine isn't used very much, but is offline right now) Most of the times we lose it on the above machines but for the last couple of days I lose connection on the main one. I can usually get it back after unplugging the router for a few minutes and restarting. After a few minutes I get a yell from upstairs that " my internet is out again".

If you have teen girls, you know the yell!

Any ideas on where to begin?
Ps, she is yelling at me again! Says she can see that the network is there, is just won't connect.

Hey all,
I put a rig together for my old man about 12 months ago, it was working just fine up until recently and I'm not sure what is wrong with it.
About a month or perhaps two ago it started having issues booting, he said it would boot intermitantly when he tried to start it up. Sometimes it would take him 10 or so restarts to get the computer going, this has now progressed to the point where it no longer boots at all.
When you try to boot it, the fans all spin up and the DRAM light turns on and stays on (ASUS Mobo). The first thing I tried was running MemOK to see if that would fix the issue, but alas it does nothing to help.
Seeing as the DRAM light was on permanently and the computer wasn't giving me any POST beeps, I assumed it might be a memory issue. Since then I've tried booting the computer with several different sticks of RAM that I know work (taken from other working computers) as well as with a stick of brand new RAM taken from the ASUS list for the mobo in question. Still no luck.
I've tried breadboarding to some extent, I've pull it apart and made sure nothing is plugged in other than the CPU, HSF and PSU. When I do this the fans spin up and I get the beep code telling me that I have no memory installed (as expected), however as soon as I install any memory I am straight back to the old issue of having the DRAM light go red and no action (other than power to the fans).
Tonight I intend to try a different PSU just to check that it is no... Read more

I've built around 15 machines in my life time and can usually troubleshoot them no problem, but my current, main machine is giving me trouble. I'm not sure where to start with troubleshooting and am looking for suggestions. Due to a variety of issues which all appeared at the same time I'm in a tossup between a Win7 issue or hardware failure or both.

It sucks because I just threw away spare parts last week, so I have no other mobo or powersupply to try swapping. I'd like to have this figured out before I start randomly purchasing new hardware to swap in.

Sorry for the rambling length, but it's detailing everything I've tried.

Here is the timeline of my odd scenario:

Problem 1. No Power) My machine was running great after about 3 mos. of a fresh 64-bit Win7 install on 3-year old hardware. Then a few days ago when I'd go to power it up in the morning, nothing would happen -- no fans/led's. That's weird because it was shutdown properly as it always is. There were no power surges or outages overnight.

-So first I tried unplugging the PSU from the motherboard and popped out the CMOS battery and let it set for 5-10 minutes. Reassembled and nothing.

-I then confirmed power outlet was working, unplugged power cable from PSU, turned off PSU switch, unplugged mobo, removed CMOS battery, the works. Also re-set the video card. Furthermove, confirmed all fans were working, not obstructed with dust-bunnies, etc. Gave it 5-10... Read more

A:Help troubleshooting power/crash issue

At a guess I would say that your gfx card or PSU is causing the problem. Check all the cables are connected securly to your mobo and that your gfx card is secured properley. Booting from your onboard gfx seems like the right way to go.

Before I start I just want to say a quick hello, I've been looking for some help with my first PC issue that has me stumped and stumbled upon this forum from Google. Thanks in advance to the admins and whatnot for having this kind of online resource available for free, it's quite appreciated!

Anyway, to the issue at hand. About a month and a half ago I began to experience random hard resets while gaming. The amount of memory and processing power that any given game requires does not appear to correlate very much with how often the resets happen. I could be playing a game for weeks and never have a problem, or I could be playing one for fifteen minutes and have this happen.

I did some quick and dirty Google research and found some troubleshooting tips I could try, but nothing has worked for me so far. Here's what I've attempted:

- Ran Prime95 for half an hour, couldn't replicate the issue.
- Ran SpeedFan to check temperatures while gaming, no dangerous readings.
- Reinstalled the latest graphics and sound drivers.
- Ran memtest on each of my two RAM cards individually, received errors, and replaced them (the new cards get a perfect score).
- Checked to make sure that the BIOS had the right voltage/timings for the new RAM.
- Ran a full virus/malware scan at boot time
- Ran CCleaner
- Ran chkdsk at boot for both hard drives

I'm not too sure what to do at this point; there's always the deductive strategy of replacing parts one by one, but (like many these days) I'm not made... Read more

I have three computers on a peer-to-peer network. The primary one is Win98, the other two are Win98SE. They are connected by 10-100 Ethernet, wired. My main company program is a DOS program on the primary computer. The other two computers have recently slowed down MASSIVELY when trying to open and use the DOS program from the primary computer, to the point that the program is unuseable because of the wait time for something to happen. I can't think of anything I did to any of the computers before this happened.

Is there some troubleshooting method for networks buried in Win98? Any ideas what I could look for that might cause this?

The company that I currently work for has a server (windows server 2003) and roughly 16 desktops throughout our building (yes we're small).

For a while now, when one of employee's has had an issue, I'd use a remote desktop program (DameWare Mini Remote Control) to view what was happening and attempt to resolve the issue. Unless it was a hardware issue, other wise I'd be able to address most issues without having to walk to the other side of the building.

Long story short, we recently hired a new QA manager. He claims that remote trouble shooting is a very poor way to trouble shoot, identify, and fix problems. I was curious how true this is. According to his claims, if Access (or any other program) is having issues making their connection to the server, when I remote in, I could be re-establishing the connection, which won't give me the ability to replicate error/issue.

I've never heard of people saying remote troubleshooting is an extremely poor way to view issues/try to fix them. But I may be wrong.

Any advice (and do you have documentation/references to back it up regardless of if you agree/disagree).

Thank you for your help.

I have 4 computers on a mixed WinXP Pro and Vista network with a linksys wireless router and dsl.

One WinXp machine is plugged directly into the wireless router with Cat5 cable and there is a desktop with a linksys wireless card and 2 laptops.

The workgroup I named Workgroup. Each computer has a unique computer name. The computer that is wired directly to the router is called JOY-DELL.

I can see the other computers and they can see this Dell, but when they try to access it, they get a message access denied. Error Code 0x80070005. The other WinXp machine said that it might not have permission, contact the administrator, etc.

On Joy-Dell, file & printer sharing is enabled. Folders are shared.

They all have AVG Internet Security and I went into the firewall settings and made the linksys router to 25 safe zones, also setting for Small Network. I even at one point disabled the firewalls.

They can ALL get on the internet just fine, which tells me it's something else.

After doing this rollout of the communications agent, the network seems to be slowed to a crawl. Is there some free program that I can get or use to check why its going so slow? I am new to this job and unfortunately have no one to help me, so Im completely at a loss here and people are slowly getting mad.

What's it plugged into? (Switch, what model, what type of cable, etc)

What type of server?
What's processor load? (CPU, disk IO, etc.)
What processes are loaded? (Look at taskman)
What's it connected to? (Do netstat -no)

For what it's worth, a very common problem on switched 10/100 networks is Link Speed/Duplex. I wouldn't exactly call FastEthernet link negotiation reliable. If the NIC is forced 100/FULL, or the switchport is forced 100/FULL - the other side will never try PHY negotiation and will more often than not end up with mismatch duplex.

I've talked to a friend who lived in a similar complex and he had a similar issue. He said that his problem was that his ISP used a DDNS, and not the static one (like my previous provider COMCAST).

The problem seems to be me losing my connection. I'll either be playing a game or surfing the web when all of a sudden, the internet stops working.

I have a D-Link DI-624 router that is acting up. I have 2 computers connected by ethernet cable and a laptop that I connect via wireless. The router occasionally reboots itself, causing all connectivity to cease. It also will occasionally just drop the wireless connection and then reconnect after a few minutes. I read on a another forum that this issue might actually be caused by my ADSL connection somehow. I find that hard to believe but I have done everything I can think of (firmware upgrade) on the router and it still acts up.
Is there a good way to determine that the phone connection is not the issue?

Hello! I have a common problem, but I can't seem to find the right answers! I am fairly experienced with PC hardware. I've been troubleshooting this problem for a couple of hours now; I checked if everything was installed properly on my motherboard and everything is plugged in quite snug! I'm torn between it being a power supply problem or a motherboard problem.

Let me tell you the series of events that happened within the last week;
About 5 days ago,I noticed that a TON of dust was caked on my heat sink fan and dust had formed a nice layer on my motherboard and graphics card. I gently cleaned it out with canned air, and cleaned out the dust from my heat sink with a q tip, pretty much just collecting dust slowly. My PC was abnormally cool as it was, so after the clean up it was doing great.
Last night I was up until about 4AM doing work and my PC was running perfectly. It was cool, it was running smooth. I left it on over night so I didn't have to exit the work I had left open; I knew I was getting up rather early in the morning to continue.
I went to go back to work at 11:30AM and my PC was off! I thought someone in my house had turned off my PC to conserve power; or it magically decided to turn off.
It decided to magically turn off, and break. Hah.

You really have to completely disassemble the heat sink from the CPU in order to properly clean it. Q-Tips cannot reach where the dust lies next to the CPU, the most important area to clean. You were most likely too late, in doing this much needed cleaning and the CPU or the motherboard itself has fried

I got my Fiber line installed about 2 months ago. The offer I pay for says 1Gbits/s down and 200Mbits up. Naturally, I've never even gotten close to those speeds. At first, when the guy did his thing, I didn't have an Ethernet cable on hand (despite being a network and IT student...I know, the irony), so I used the router's Wifi. I was averaging 70 Mbits down. At first, I was thinking, 'this seems a bit low'...for fibre of course). I went into lectures the next day and people said, you may need to wait for your line to be properly activated...this seemed plausible, so I waited. The next week I stuck an RJ45 on some CATVE and immediately went to average 500Mbits/s (688Mbits/s record). Now, this is great, but it's still half of what I'm paying for.

However, for the past 2 days, I've been having problems. My Desktop (after coming out of sleep) always has the yellow triangle symbol over the wireless icon (faulty ethernet cable so was back to WiFi). I disconnect and reconnect to find the same problem. I restart the wireless on the router, to find the problem is persisting. Only after 3-5 tries does it work. My phone too has been having trouble connecting to WiFi (Authentification problem).

The original CAT5 cable has since 'developed' a problem and has been changed. The Pc hasn't been having the connection problem out of sleep, but Chrome is very slow to do anything. Youtube loads every other time, social media too. I... Read more

I just recently did a clean install for my new SSD on my alienware m11x and have been having problems with inconsistent download speeds. I made sure I had all the correct drivers and was pretty thorough in doing so (to the best of my knowledge.) After a week or so of no luck, I think I may have stumbled upon the source of the problem. I troubleshooted my wireless network adapter and it showed that it had fixed the problem. Unfortunately, this was not the case. I ran it again and it said that it had fixed the problem. Again, this was not the case.
Troubleshooting the error is not fixing the problem. What will!?

I'm using Windows 7 64 bit. My computer came out of sleep mode on friday without internet access. I immediately placed a support request with my network provider (I live at a university) but they have yet to respond. In the meantime, I'm treating the issue as though it's originating with my hardware and not theirs.

I've tried updating my network adapter driver, reinstalling the adapter, disabling services like Bonjour, restoring my system, entering safe-mode, releasing/renewing my ip, malware detection, disabling tunneling adapters, disabling IPv6. Finally, I lost my mind and tried a full reinstall of windows. The problem persists, unchanged.

After looking at the attached information, is there anything else that you would suggest I try?

Dunno if this is better in the networking forum or the printer forum but i thought i'd give this forum a try as i tend to think it may be the network but need opinions and why.

The problem is:

I've got a Kyocera FS-C5016 Laser Colour printer on a network (connected via TCP/IP not shared). I did one print to it this morning and that was all it would do for the rest of the day. I've tried to ping it, but failed. I've changed IP address,no luck. I've tried same ethernet cable used for this printer on a computer and from this PC I could ping other PC's and gateway successfully. I've powered off/on my switch and DSL modem, still no go. I've checked all network configurations on the printer, and all look good.

I've hooked my laptop to this printer with a cross-over cable and I can ping and print perfectly (same IP address on printer), never failed once. I've also hooked this printer to another PC's via cross-over and no problems there.

However as soon as i hooked the straight through cable to the NIC on the printer, bang, no ping,no print, thus no go. Printer says "Ready" on LED. I can perform internal prints without problems.

I have since added a add-on NIC to the printer giving it the same IP address as the onboard while having disabled the onboard NIC on the printer. I can ping, print etc all without issue. As soon as I disable this add-on card and enable the onboard NIC and reattach the straight through c... Read more

A:Solved: Network Printing troubleshooting -- weird one!!

I've never dealt with other than shared network printers, so my only question to toss out is have you tried reinstalling the printer software on the network? Or would such a setup even require printer software to be installed somewhere?

hardware concerning: ethernet, specifically nforce4 network controller (drivers

situation: Assigning pc to static ip of router (wrt54g) ie; 192.168.1.xxx default gateway, and primary dns as

problem: upon bootup the network can not find the proper route and has to diagnose/troubleshoot to fix the problem, which was a nag every time and gadgets like weather and such would not be updated until this was resolved. If leaving network to dhcp the problem would not occur or nag. Yes dhcp set on router.

solution: simple really, going to nvidia's site and installing the latest nforce4 platform drivers fixed the problem (which i think is just a reinstall of the drivers as i think they are the same that are packaged with win7 7000. Have not checked this yet to confirm

I was having a real problem that ate up many hours
(see techsupportforum.com//networking-forum//94185-asymmetric-file-sharing-error.html) but a moderator on this board (johnwill) posted a helpful checklist. (see second post in above thread). In addition to that, I found my problem solved by booting windows xp into 'safe mode with networking'. This allowed me to identify the fact that my problem was caused by some application running as a process in the background. Eliminating the processes one by one from a normal booted machine, eventually restored normal networking and identified the culprit. I post this as a first step that might help anyone with a frustrating windows xp networking problem.

A:a good windows xp network troubleshooting checklist

That is one of the major premises behind safe mode; that it is just windows so that you can troubleshoot possible sources of errors either by creating new user accounts, or disabling various programs from running.
The inclusion of network support in safemode is a real big help too since it allows you to run online scans too.

Im using Windows XP Professional on both my desktops.
I am using a Netgear 108 mps wireless router, WGT624v3
And a LinksysWireless-G PCI Adapter.
I have completed the setup, I have good signal strength. However I cannot connect to the internet, and The adapter is saying the it is "Aquiring Network Address"
Under the support tab, it reads that I have an invalid IP address and lists the ip address as When I click repair it reads renewing ip address but never seems to renew itself.
I have disabled my firewall restarted both computers, router, and adapter multiple times and still have no success. Please help with any advice or recomendations.

Much appreciated

A:Wireless Adapter - Acquiring Network Address Troubleshooting

If your "setup" includes encryption and MAC addresss block or other filtering/security methods you should only add those incrementally as you know other stuff is working

Startout just trying to connect to a simple wireless broadcast and verify your adapter sees the SSID being broadcasted by the router.

My machine has been experiencing intermittent BSODing over the last few weeks and I wonder if you could give me a hand troubleshooting it? I'll summarise what i've done so far. It's not given me anything today, as I say, it's intermittent.

System Info:
Processor Name: Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz
Processor Information: Intel64 Family 6 Model 60 Stepping 3
Graphics Information: NVIDIA GeForce GTX 780 Ti
Mobo: Z87I-PRO
System BIOS: 0903
Installed System Memory: 16 GB
Operating System: Microsoft Windows 7 Home Premium 64-bit (originally installed on system)
Age of system: 1 year, 1 month
OS Reinstalls: None
This is a desktop PC
System Manufacturer: Purchased from ChillBlast
Troubleshooting so far:
* Checked EventViewer for after the crashes. The only useful thing showing is that the Kernel service is shutting down - which I suppose it would if power to it was interrupted.
* Opened up case to check components. Everything seated well. Extremely tidy cabling (if I may say so myself; nothing getting in any fan's way).
* Ran GPU stress test - all fine.
* Ran Processor stress test - all fine
* Ran driver verifier (ran for about 20 minutes) and nothing crashed.

Attached Files:
* PerfmonReport
* Your app collection dump
* IPDT Processor Test results

Appreciate your support :)

I have four computers that are connected at any given time to the home network. I believe have two issues here.

The first, all of the computers connect and surf the Internet at very slow speeds. Sometimes it seems like I'm back on Dial-up. My MacBook (which is my main computer I work from) connects to the Internet with an Ethernet cable directly into the DSL box. Even if I turn the other three computers off in the office I still run slow on the Internet. Any thoughts on how to improve this? My DSL provider says its an issue with our setup. Great thanks for the help!

Second, my Mac overall seems to be running very slow. I have over 14GB of available space so I would not think that the computer is in overload.

Any support would be greatly appreciated.

A:Moving at turtle speed - Internal Network issue or DSL issue?

If you have more than one computer, and all exhibit the same symptoms, it's hard to believe they're all bad.
Pick one that doesn't exhibit any other issues and do this:

Register at DSLReports and run their Line Quality Tests. It's best to run this test with a direct wired connection to eliminate any wireless issues from the results. It's useful many times to run this test several times, and we'd like to see each of the results. Post the results link from the top of the test display page for each test run here.

The link to post is near the top of the page and looks like:

If you wish to post this result to a forum, please copy/paste this URL
http://www.dslreports.com/linequality/nil/2357195 <- sample only, yours will obviously be different!
and your IP will be disguised.

Copy/paste that link here.

Note: You will have to enable PING (ICMP) request response either in your router (if you have one), or in your computer's firewall for direct modem connections. This is very important to get the most important part of the test to run.

Hi dear,
Thanks in advance for your sincere help in this issue. The laptop was running fine before automatically the print stops. The printer is fine and other can print from their pcs and laptops. It is confirmed there is no issue with printers. I have an issue with network print from windows 7 64bit Laptop to HP Network Printer Laserjet pro 400 M451nw or any network printer. I have successfully installed network printer by IP address and it is installed successfully with correct drivers. When i try to print it wont print and print will be in the queue. when I delete the queue after deleting it will show the status of the printer's toner and usage. What things stop print command to reach printer? Any printer port is blocked? I have uninstalled maximum apps, updated windows 7 64bit OS, updated and downloaded HP drivers. Uninstalled and reinstalled HP drivers. All vain. Can you please help me. I will be grateful to you forever. Thanks alot. Is it O/S issue?

Strange issue.

In Devices and Printers right click on the printer and select 'Printer properties' (not 'Properties at the bottom of the list). On the Advanced tab is 'Always available' selected?

Hello, I am posting here in the hopes that someone will be able to help me figure out what is wrong with my connection or possibily PC - as I'm unsure as to which is the problem.

My PC is on a network in the building that I live in. Previously I was on a wired connection and things were normal as far as internet goes. I could play games, browse the web, use voice chat, etc..

Recently, there has been a new addition to the building and I was forced to have to move my PC location. However, there were no cables available, so I had to switch to a wireless card. Now I get random DCs from the game I play online and it's starting to drive me crazy and the people that I play with online.

It always happens one of 2 ways. Either [a] the game and ventrilo lock up/lag out for like 10 or 15 seconds and then I get disconnected, and am able to immediately reconnect (which while better is still really bad) or the game and ventrilo lock up/lag out for like 10 or 15 seconds and then I cannot reconnect without either rebooting my PC -or- going to my wireless connection window and disconnecting and then reconnecting to my wireless network.

I always get really angry because even when I'm locked up/lagged out and disconnected, I mouse over my network icon and it tells me that I'm connected with great signal strength and that everything is fine, and yet these disconnects keep happening. Sometimes twice in a night, sometimes 5 or 6 times.

I am pretty heavily involved in the ... Read more

I have attached 2 pictures to show my issue.

First of all I have a Netgear R6300 wireless router. On the Network window is shows as a gateway. I am pretty sure it was displaying as a router on Windows 7.

Second when I try to get display the network map I get the error message that is attached.
Could anyone figure out how to display the Network Map?


A:Issue with Network Infrastructure and Network Map

I don't think it's anything to worry about. Most likely, you don't have UPnP enabled on the router, so Windows thinks it's a gateway. The only difference between a router and a gateway is that a gateway works between two dissimilar network types. For example, a Cable Modem is a gateway.

The error message is just saying it doesn't know how to manage it, which is probably as I said with no UPnP enabled.

I am hoping this is an easy answer for someone and appreciate the help. I have a laptop from work that I cannot get to connect to my network. It sees the network and shows the SSID. It even asked and allowed me to enter my WEP key. When I hit connect, A window that states "Please wait while windows connects to 'XXXXXX' network. Waiting for the network..." And under that it has that little green bar going from right to left.. Then it times out, (I guess), the window closes and it goes back to the choose a wireless network window I had open. It doesn't matter if I'm 1 foot away or in another room, the signal shows full bars. I CAN however connect to a neighbors unsecured network (with one bar of signal), and connect at public Wifi locations without difficulty. It's a brand new HP with XP professional and all updated drivers. Some background, as I'm not sure if its a setting with my router or laptop. I have a Westell Versalink 327W as my router. Both laptop and router authentication set to open. I was able to easily connect with an old personal laptop (XP) before it died. I can easily connect to the network with my daughters Ipod, and Wii. I had a friend's netbook (XP) here and it connected fine, but his other laptop (XP) had same issue. My current laptop from work was recently replaced, and the old one (also XP) had the same issue.
