Inability to Connect to Network and USB Device Failure

Q: Inability to Connect to Network and USB Device Failure

I lost connection to the Internet and to my home network and have since been unable to reconnect. My computer was the only one in the house that was affected. I am connected directly to the modem via Ethernet.

Simultaneously, Windows gave a warning that an unknown USB device failed. All devices connected to USB ports are functioning normarlly. I do not have a WiFi transceiver connected to a USB port.

Preferred Solution: Inability to Connect to Network and USB Device Failure

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I've been booting to Windows 8 PE [a special version with lots of utilities]
and I've twice backed up the RAID array, and both have apparently failed.

The first:
I used ReclaiMe Free Raid Recovery: and it made a copy of my recovered RAID array, and I put it on a 500gb SATA drive:
but the drive image didn't boot correctly: it was missing a windows logo when it booted, and it had 2 users: Admin and [my name] but neither would boot right.
The admin would boot up, but showed a blank desktop and failed completely. The [my name] normally has a fingerprint access, which was unavailable, and wouldn't even accept characters into the password field. It was a dead end.

The second: I used DiskInternals Raid Recovery 3.1, and it did a [complicated] raid analysis for me: I think I did the right thing by taking a 448gb Raid array file, and exporting it to a .dsk file: That was the size of my RAID array, of 2 disks -- it should have been everything.

Greetings, this is my first post here on this site, but I do not know where else to turn.

I have Kazaa Pro and there are three separate servers I connect to to retrieve dl's. Gnutella 2, Gnutella 1, and Edonkey. Edonkey is never connected, which I don't mind, but Gnutella 2 is the primary server on which I retrieve dl's from. For some reason, it is staying disconnected, only Gnutella 1 is connectind, but the dl's are minimal at best. This is what I have tried so far...

Querying the different servers individually.
Adjusting my windows firewall.
Resetting the Port that I retrieve off of.

Now I have recently gotten a laptop and thus a router, Netgear to be precise, from Comcast Cable. I don't know if that is causing an issue, but perhaps someone knows something I don't..

Any help would be appreciated

I have, just this morning, discovered an inability to connect to the internet. On websites I get the message "Server not found" I can get the firefox start page and nothing else. On start up it takes a long time and the internet icon shows a yellow exclamation mark. I am writing this post on another computer, that is why no TSG SysInfo. I did get a warning that emsisoft was interfering with something (I don't know what) so I tried to delete it, but couldn't find it.

A couple years ago, my computer got a virus on it, and I (thought) I cleared it out. Now I'm trying to start up this computer again to run some of my recording and music production software. When I turn on the computer, it always logs in, but 75% of the time will then freeze and I am unable to do anything. (But the mouse on the screen still moves.) When I am able to log in, and use the computer, I am unable to access the internet. It shows that the cable is connected and that it is sending and receiving information, but when I open up any browser, it fails to load a page. Since I am unable to connect to the internet, I cannot access any security software or run any scans of the computer. I have tried using Malwarebytes, but that too failed to install. I have read many forums saying that it may have something to do with a PCI card, but I'm highly doubting it. I talked to a friend just today, and said that it may be a corrupt driver or that the virus is not completely removed. I would really like to get this computer in working order, and any help or advice is appreciated!! Thank you in advance,

A:XP Freeze and Inability to Connect to Internet

Start>Control Panel>System>Hardware>Device Manager

Click "show hidden devices", uninstall all flagged devices and let XP find them on reboot. Report any that remain flagged.

Even if the LAN is not flagged, uninstalling it and letting it reinstall may fix it.

Freezing can also be caused by system file corruption caused by heat, bad power, and hard drive errors.

Run chkdsk. Report results.

After weeks of having internet problems, the internet is up and running again. for everyone other than me. i can connect via cable, which i am doing now, but cannot connect to wifi. my landlord had attempted to change the key at some point, so i had typed in that one, but now i cannot seem to get rid of it. the original key seems to work for the 2 other computers in the house that have wifi (both MACs) but not for me. when i attempt to connect i type in the original key and it "thinks about it" and says that it will be automatically connected, but never connects. i get no message saying that any information is wrong or the key is wrong. but when i go into the advanced settings and go into the properties of this wifi, it seems to remember a shorter key.

I'm having a problem connecting to the internet on my laptop, currently, I'm using my family desktop computer. My laptop is running Windows XP Professional, Version 5.1.2600. It is a HP Compaq 6715b and I am running a Broadcom 802.11b/g WLAN Network Adapter. I'm not particularly computer savvy so if more information is need please let me know. I use this laptop for school, and considering all of my courses are online this presents a huge problem for me.

On Friday morning my laptop was working perfectly as usual, and I decided to take it to a local coffe shop that offers free wifi for a tutoring session. I was sitting outside and connecting to the shop's wifi fine, but then it started to drizzle so I moved inside and not only did I lose my connection, I couldn't get it back.

I noticed that two icons usually in my taskbar (directly next to the time) were not there, the Local Area Connection icon, and my Broadcom Wireless Utility icon. The latter is what I use to connect to the web. So far I have done everything I can think of to figure out the problem:

-opened network connections and examined the properties of the two connections there (1394 connection and Local Area Connection)
-tried to connect directly to my router via ethernet cable
-tried to open the Broadcom Wireless Utility under all programs and nothing happened.

When nothing happened after trying to start the Broadcom Wireless Utility I decided to check the program because it wasn't w... Read more

Adding WPA 2.
I use DD-WRT v24-sp2 (06/03/09) mega - build 12255 [and it's worked well for several years] on a small unsecured home network in order to increase the range.

When I set this up several years ago I added a specific nondefault username and password to the Linksys 610N v1 router. Now when I open, DD WRT either shows me my username with a hidden password or goes straight to the various tabs and I can make and save changes in the DD WRT options.
I never got around to adding any security to the any of the devices all of which work perfectly through the router.
However now, I set up a new connection on Windows 7 and added WPA2 with the router password but this new connection does not connect. I cannot make it connect automatically or manually. Even when I put the original DD WRT as first in line to connect it does not connect until I manually click the connect button.
When I add WPA2 and AES to the (which usually has no security enabled) I lose connections from both the connections, the one with and the one without security enabled.
I have confirmed that I have the correct username and password by opening DD WRT with a new browser.
I have read multiple “How to's” without benefit. Since DD-WRT works perfectly it seems to me the problem is in W7. It seems like I have some basic misunderstanding (usually) of security or my system is somehow different.
I will greatly greatly appreciate advice.

A:Adding security > inability to connect

Hello gwatts and welcome to SevenForums!

From the sound of it, I believe you set up a username/password for accessing the router's built-in web interface, which is what you access in your browser by typing

You cannot use this password for WPA/WPA2 encryption; this is set up with a completely separate key. You should first set up WPA2 encryption using your router's interface, creating a new passkey of your own choice in the process. Then you set up your clients (the computers connecting to the router) to use the same passkey.

The exact steps to do this depend on your router model. Do you have a manual for it or are able to download one from the manufacturer's webpage?

Here is a tutorial I found via Google: Tutorial: How to set up WPA2 on your wireless network - Computerworld

It's kinda old, from 2006, but should help you get a basic understanding of the way WPA and WPA2 work and how to set them up.

Hello all,

I have been running Vista Ultimate 64bit SP1 for a few months now. I have not had any trouble with it up to just recently. I am connected to the network using a wired connection and have the same workgroup name as the XP machines on the network. My files are stored on an XP machine that is used almost exclusively for this purpose - we call this the 'server'. I also run a couple of programs remotely from that machine, notably my mail program (Pegasus Mail). As I said, with all this until recently I had no problems at all with this setup.

Now, on this Vista machine for a reason that I cannot fathom I am having a very slow connection to the files on the XP machine on the network. (Other XP machines on the network have no trouble accessing these same files quickly and effortlessly, though they are much older rickety machines by comparison with this one.) Some of these files are on the 'server' machine itself (on a Raid 5 system) others are on a Mybook external hard drive which I have removed from this Vista machine and connected to the XP one - in case this was causing the problems. I am not able to access my email program except painfully slowly and with frequent crashes or messages of 'not responding' though eventually the program catches itself and recovers. But obviously this is not workable.

I have tried to remove all sorts of devices in case they have suddenly caused conflicts (webcam, removed the Mybook from my own computer etc.). I have also replaced the net... Read more

A:Sudden go-slow or failure to connect to XP network machines

How is your internet speed on the Vista machine, has it slowed down too? If so, take a look at your Windows Update history, see if WU updated a new driver (or have you recently updated the driver?) for your network card that might be causing some problems and roll back the driver to your previous one.

I have a linksys wrk54g wireless router connected to my cable modem. Off the router runs my desktop, roomates wireless laptop, my wired xbox360 and my roomates wireless ps3.

My problem is that when i play online games on my desktop, i momentarily get disconnected from the internet....for a couple seconds and drop the game I'm in whenever either the xbox or ps3 are turned on. I also get disconnected from other online programs such as aim/xfire but thats not as bad cuz i just log back in right away. It is pretty annoying and i believe it is a problem with my router somehow?

I am semi competent at computers and setup the network myself. Please if any1 has ideas or has heard of this problem before id appreciate it.

sounds like you have a duplicate IP address on one the the boxes

get a connection and make sure you can browse the Internet using google
and search for anything you like (we'll use this as a test)

Connect a device and make the browser search again (even on the same words).
If you get disconnected, then the last device connected has the conflict.

Go to that device and REMOVE any static IP address and make sure you have
Automatic DHCP for the IP and DNS addresses on that device.

My computer keeps freezing on me. However, it freezes around 5 mins after startup. Another thing is that I'm unable to connect to the internet as well (it shows that I'm connected, but I can't go on FireFox, etc.). Now I'm fairly sure that it doesn't have anything to do with any recently installed software. Also this problem came upon me when my computer was running normally, then my internet just stopped working. I restarted my computer, then it started freezing and so on. I've done virus/spyware scans on safe mode and nothing seems wrong with it. Anyways that's my problem, hope it can be fixed (without reinstalling hopefully).

P.S. I think this is the right section, if not I apologize.

Hello all,

My laptop is the only device that is unable to connect to the wireless internet in my new house. There are at least two other computers and three other phones (including mine) that have no problems connecting to the network. My laptop is a Dell XPS M1530 running on Windows Vista. The wireless router is a Cisco Linksys Model No: WRT310N.

I have never had a problem connecting to any wireless networks in the past, but when I try to connect to this new network it fails every time. After the first two minutes it says "Connecting to network taking longer than usual" and then it says "Connection failed" because the network timed out.

I have Norton Antivirus, and have disabled the both the Norton and Windows firewalls. And I tried to find a driver to download, but I couldn't find any that were compatible with my computer and the router.

I have run out of options and am close to just buying a new router. I would appreciate any help you all are able to provide.

Thank you in advanced!!

Remove the wireless security
Is your wireless security enabled?
if so - log into the router and remove the wireless security - now see if it will connect.
if it does - log back into the router and try with the wireless security enabled again

Run Xirrus Wi-Fi Inspector
Download and install
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.

I have a laptop Asus G55 with Intel Advanced 6235N Wireless Card. This laptop has been working fine all this while, but off late i started getting a weird issue.
1. This laptop started dropping wifi connections atleast once a week.All my other devices: Phone and Nexus 7 are able to connect fine.
2. I did a factory reset and installed the latest drivers but it still didnot solve the problem.
3. Tried resetting the Wifi Adapter multiple times but it didnot help.

When nothing worked, I just reset my wireless router(ActionTec from Verizon) and now I was able to connect successfully. Everything worked fine for a week and then I got this problem again. I reset my wireless router and it started working fine again.
What I dont understand is: why is it only my laptop that is facing the problem? Why dont other devices in the network(tablets,phones,other laptops) get the same issue?

I recently upgraded my wireless router from D-Link DIR-615 to D-Link DIR-685. Before the changeover, all of my devices were connecting to the router, although I had several problems with dropped connections, etc. The devices in use were:
- Desktop computer
- Laptop computer
- All-in-one touchscreen computer
- Netbook
- iPhone (original model)
- HP TouchPad tablet
- Sony Blu-Ray player
- Two internet radios (Aluratek and Livio)
- Wii

ALL of these devices were connected wirelessly to the network. When I set up the new router, I used a different network name/SSID, but kept the same security key/password. All of the router settings were kept the same (e.g., WPA-2, etc.). After the new router was up and running, every single one of the devices listed above connected (after an initial setup with the new network name, of course) EXCEPT the All-in-one/touchscreen computer. I've tried over and over, and it refuses to accept the security key/password. (The desktop, laptop, and touchscreen are all running Windows 7 64-bit Home Premium.)

After doing some research, I tried some suggested solutions, but nothing seems to work. Nothing on the problem computer has changed since it was last connected to the old router. I checked the "Properties" of the network device on both the Desktop (which has no problems connecting) and the Touchscreen, and they are identical: WPA-2, AES, etc. And I'm 100% positive I'm entering the security key correctly.

I've tried many network settings, turned off Windows Firewall, disabled IPv6, etc. So I am looking for suggestions on what else to try. My understanding is that Windows 7 Embedded installs less than other Editions by default, so I suspect that some software

I have a friend's laptop (Toshiba Satellite L645D-S4040) that she recently got and I can't get the wifi on this thing to work. The built-in wifi card shows fine in Device Manager, but, if I attempt to use it in a network, I get a vague error about driver issues. She got a USB wifi adapter, as well, and the same thing is happening with it. I've installed the drivers from the Toshiba website and made sure they were up to date with Windows for the built-in card and used the CD that came with the on networks wifi adapter to install that driver. Neither adapter shows up in ipconfig /all, either.

Might anyone know where to go next? I could reinstall Windows, but I fear there's something simpler I'm missing.

Hi, hope I can get some help here. My laptop was able to recognize my network & signed on, no problem. It couldn't recognize other networks in the area, so if I went to a wifi hot spot, I was out of luck. I kept getting this message (paraphrase): "WZC wireless zero (configuration?)" with some numbers & stating I needed to go to that article number at the Microsoft website. Whenever I tried to refresh to see what networks were in the area, I got that message.My modem/router quit working so I thought it was a good time to get it figured out. Due to the reference to the article, in the aforementioned paragraph, the PC tech had me put: %systemroot%\system32\services.msc /s, then "RUN". It came up with a service: SQL server configuration manager. The tech had to open another program associated with SQL or SQL is the associated program? The tech made a couple of settings & he was able to sign onto the wifi in their office. When I got home, there was this glitch in that I needed to restart to get onto my wireless network. Then I figured out that I could disable then re-enable. I am able to recognize the networks in the area, but I have to go into "Network connections" then I have to go to "wireless network connection"; click "disable" then re-enable.

My problem is that everytime I connet this flash drive to my laptop's usb 3 ports, I get the message "This device can perform faster if you connect it to a superspeed usb 3 port" (!!) so I dont get it! What is wrong??

Actual writing speeds, when i copy large files (eg movie) this is done at 28 - 30 MB/s while speeds when copying many small files (folder with many smaller images) is done at 10 - 11.5 Mb/s.

I also have a usb 3.0 Seagate hard drive but I dont see this message everytime I connect it. Also, the exact same test (with the exact same files beeing transferred) are: Large files (eg movie) at 90 - 95 MB/s while smaller files (folder with many smaller images) is done at 34 - 37.5 Mb/s

I know that the Samsung SD card can't achieve the same speeds, but I am mostly curious why this message comes up "This device can perform faster if you connect it to a superspeed usb 3 port" . Is my flash drive operating at usb 3.0?

Thank you for your h... Read more

A:Your device can perform faster when you connect it to a usb3 device

Hi Dionisis , I have a couple of USB 3.0 flash sticks that give me the same message even though I have them in a USB 3.0 port.
In your case it may be due to the fact that an SDXC card isn't really a USB device, I'm not sure on this. someone else may have a better explanation.

You can run comparisons using the same files and copying in the 2.0 and the 3.0 ports to see any difference.

Running Windows Vista Home Premium with Service Pack 1.


I am hearing the Device Connect, Device Disconnect, and Failed to Connect sounds at random times, sometimes 2 minutes to 10 hours apart. No error window pops up when this event occurs, nor do any event logs record anything out of the usual when these events occur. It does not appear to be connected to any specific program or application that I run.

I have scanned my computer with multiple virus scans and malware scans. I have observed firewall connectivity and it appears that whatever is causing it is not trying to connect to the internet. I have full confidence that it is not an infection. I have also reinstalled the OS and applied the updates, but the problem is still there. I have done a driver check on all the hardware and all drivers seem to be in order.

To me, this is truly a phantom problem that has driven me to wits end. I apologize if the information seems lacking, but to be honest it's pretty much all I konw about this problem. I would be greatful for any comments or suggestions.

A:Device Connect/Disconnect/Failed to Connect sounds

What do you have connected to your USB ports?
What are the settings in your Control Panel to control the activity of the USB ports (in particular, any settings that sleep/disable that device when it's not being used).

The easiest thing to do is to disconnect all your USB devices and only connect them when using them. Also, follow the Safely Eject Hardware protocol when removing them from the computer.

Might be a stoopid question ...

My XBox360 is wired by ethernet into my home network (via Devolo homeplug behind TV).

My music server (Win7 netbook) is not wired, but on the wireless network.

Can I get the XBox to "see" the media folders on the netbook (to play music etc.) using this setup or do I have to have both clients on the same wireless network ?

The Xbox automatically disconnects from the wireless network when ethernet is used.

For one thing you can type event viewer, in search, and see what error was happening at the time involved.

A way to determin the cause is a clean boot.

Have a USB wireless WiFi unit. To connect to the Internet. Have to disable the Local Area Connection. When connected to the Internet. If I enable the Local Area Connection. Unable to connect to the Internet. When I disable the LAC, the Internet connection is restablished. Using a D-Link boradband VPN router.

A:Wireless Network Connection will only connect to Internet if Lcl Area Connect disable

sounds about right! Your big issue will be the VPN, as it is frequently specifically
config'd to use a specific adaptor AND to force all tcp traffic thru that connection,
even though you want to do some trivial google.com search.

Consider using a Hardware Profile to define
1) a LAN connection environment (ie no WiFi)
2) a WiFi environment (w/o a LAN)

the choice occurs at boot time and the hardware is enabled/disabled per
the profile.

Hi,My brand new Yoga 720-15 IKB doesn't connect to my workplace wifi network which is a Mikrotik network. It does though connect to my home network or a mobile hotspot and works fine with them. I have installed all Windows 10 updates and Lenovo Companion updates. I have manually updated wifi card driver, I have also tried deleting network card and installing it again - but no success. Still doesn't connect to this one particular network in my workplace.To make it stranger my coworker has the same brand new Yoga 720, the only difference is that mine Yoga is grey and his is platinium color. We discovered also that two, supposedly the same computers  have different network cards (he has Intel, I have Qualcomm Atheros QCA61x4A. This is a bit weird).I have also found out his Yoga connects easily to VPN at our workplace, my doesn't.Any ideas how to solve it? EDIT: my current network card driver is

I have a lenovo u160 running windows 7, a couple of days ago it seemed my computer was infected with something, giving a series of security warnings I had not seen before (not av security suite). It slowed the computer down for a few minutes.

After closing these messages, there seemed to be no problem, but then my computer was no longer connect to the internet. It connects to our router/wireless network, but not to the internet.

I tried resetting and unplugging the router and the modem, but still no luck. We have two other computers on the same network that are connecting to both the network and the internet.

I tried running rkill and malwarebytes twice and no malicious items were detected.

I restored the computer to an earlier point (2-3 days earlier)

On the toolbar in the bottom right of the taskbar, it shows a 5 white signal bars, with a "!" inside a yellow triangle.
If I click on the network button it states it is "connected" to the network. It describes the connection as "excellent" (4-5/5 bars).

Above the display of the available networks, it states

"currently connected to:
Unidentified network
No Internet access"

I am not computer savvy and have not run into this problem before. Thanks for your time and help.

She keeps loosing connection, then has to wait until it decides it can connect again. She would wait about five minutes and then click on something and would gain access.


the symptom has been occurring for at least a month and more.

We are on a wireless network (Uverse) and have not had any problems with this wireless network

One thing i notice is that her icon for the connect shows one less bar than mine shows. I should be the same. they are both HP machines and sit in the same spot.

when it is not connected and the icon is clicked it does not show our connect name as an option. Sometimes rebooting solves the problem, sometimes clicking 'connect' does. It will work for a while and then she looses the connect.

I am not sure that her problems started when she got that "conduit" search malware. I had only partially removed it, it was still resident when another tab on her firefox was opened. Yesterday i found some additional information to remove the settings from registry and thought that had cured it. But apparently it did not, we are now back to the disconnect problem. last i tried it it wouldn't even connect on restart. Right now she is saying that its been doing pretty well for about five minutes. Probably wont last long.

I don't really know why this all started I think it went back before the 'conduit' thing got installed. She usually doesn't say anything to me she si... Read more

How far away from your computers is the router? Also; have you tried to power cycle the modem and router? If not; i would try that. Unplug both the modem and router; wait about a minute; then plug in the modem first; let that boot; then plug the router back in and let that boot. Try doing that and see if it helps the situation.

I hope I'm in the right forum. Computer has been running good. Suddenly this morning I get a window that a USB device has failed. See screenshot attached.

I would say this has to be the USB 6-plug unit I bought. I unplugged the 4 items I have attached to it and plugged them back in different slots. I unplugged the unit itself and plugged it back in. After I did that I got that deal in the taskbar showing that drivers were being installed and after it was finished it simply stated that my devices were ready to use. I went into Device Manager and couldn't see anything amiss there. Everything appears to be working.

If anyone can help with this I thank you in advance!

Sounds like your system is having a problem with the video card. I'd start by reseating the card in it's slot and see if that helps.

Heya guys (and girls),

I have been having such issues with my computer lately and I was told to come here for some help ^^. I have a dell xps 400 which is 4 1/2~ years old. On and off for the past 2-3 months, I got occasional "Keyboard failures". A simple restart, unplugging the power cord and restarting seemed to do the trick. The problem has escalated though. Two weeks ago, I tried doing my old trick of just restarting + unplugging but that had no effect. Sometimes the keyboard wouldnt work during the initial startup. I couldnt get the mouse working either, "keyboard failure" came up over and over. When I would finally catch a break and get in - "USB device not recognized" would CONSTANTLY spam on the bottom right of the screen. The error message usually contained a window of either 2 USB Root hubs with one being "unknown" or a different window with 8 USB hubs 1 of those 8 being unknown.

I've tried reformatting (twice, actually). After the second reformat (I got my BIOS updated, and service pack 3 reinstalled as well as any other updates from Windows Update) the computer is starting to work better than it was at its worst, but everytime I log in the error message pops up. Most of the time it only shows the 2 port option. It says:

"One of the usb devices attached to this computer has malfunctioned and windows does not recognize it".

Now, I ONLY use 3 USB ports. One for my mouse, one for my keyboard one for my wireles... Read more
