Hi,

Yesterday my computer disconnected from the Internet and wouldn't reconnect. It said that something was unplugged. I have a home wireless network with several computers and the others still work fine, so I assumed it was a problem with the PCI Adapter (Edimax IEEE 802.11g Turbo Mode). I bought a new one (Tenda TWL541C(P)), but that doesn't work either. It installed OK and I set up the wireless network without any problems, but it just says "Card Unplugged" and Site Survey is greyed out, so I can't get onto the network.

Please can someone tell me what I need to do to get back online?

Thanks,
Joe

Firstly I would check and make sure the PCI card is firmly connected, also make sure you have it screwed in to keep it from coming unplugged... From there I would check your services (Control Panel -> Admin Tools -> Services) make sure you have the Wireless Zero Config service on automatic... I would also check your Device Manager (Control Panel -> Admin Tools -> Device Manager) make sure you aren't having any conflicts with the driver... Sometimes you might have to uninstall, and re-install...

The PCI card is inserted correctly. Changing Wireless Zero Config to Automatic didn't help, however when I turned it off I was able to access Site Survey and see my home network listed. I was unable to connect to it however. Device Manager doesn't indicate any problems. I've tried unistalling and reinstalling the card and it didn't help.

Thanks for your help,
Joe

Here's a more detailed description of the problem:

Here are the details:
ISP - Bulldog Broadband (now owned by Pipex)
Modem - Origo ASR-8000
Router - BT Voyager 1500 Wireless Router
Connection Type - Wireless
Encryption - WPA
Operating System - Windows XP SP3
Browser - Firefox

I have a wireless home network with four computers connected to it. The other three are still working fine. On Friday my computer disconnected itself and wouldn't reconnect. The network connection icon in my tray had a red cross next to it and said a network connection was unplugged. Since nothing about the physical network had changed,

I assumed the PCI card (Edimax IEEE 802.11g Turbo Mode) had developed a fault, so I installed a new one (Tenda TWL541C(P)), but that hasn't helped. If I click on the network icon in the tray it can't find a connection. I tried setting up a new network after installing the new PCI card but it still says there's no connection. I've checked Device Manager which doesn't indicate any problems.

I've setup a profile for my network in the Tenda Wireless LAN Adapter Configuration Utility, but it won't connect. It just says "No Connection" under Status. Originally when I installed the utility it said "Card Unplugged" under Status and Site Survey was grayed out. It also told me I needed to disable Wireless Zero Config. When I did so "Card Unplugged" changed to "No Connection" and Site Survey became available. When I go to Site Survey my network is listed, but I can't connect to it.

Here's some info from CMD:

Today I tried resetting the TCP/IP stack and WINSOCK entries to defualts in CMD, but that didn't help. I also disabled my WPA encryption to see if I could connect to the unprotected network, but I couldn't. Finally I tried connecting to the router with an ethernet cable. Doing so, I was able to connect with Skype, AIM and ICQ and Kaspersky Internet Security was able to update it's databases. I wasn't, however, able to connect with Internet Explorer, Firefox or FileZilla and Counterspy wasn't able to update it's databases. Also, when I was connected with the ethernet cable, I was unable to connect wirelessly with the other computers on my network.

Has anyone got any suggestions for what I should try next?

I have two PCI slots, one containing the LAN adapter, and the other containing a card with extra USB ports. I took them both out, put the old LAN adapter in the slot containing the USB ports and put the USB ports card in the slot that had contained the LAN adapter. Now both the LAN adapter and USB ports work perfectly. I have no idea what happened, but I'm glad everything's working now.
