    Question Can't Connect To Wireless Home Network

    Hi,

    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 useful info:
    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

    Here's some info from CMD:

    Re: Can't Connect To Wireless Home Network

    I had this constantly with my BT Home Hub. It would kill the wireless connection/network for no reason. And the only solution would be to delete and re-create a new one. Might be worth disabling security on the router and workstation having problems to see if they can connect them?

    Also what happens if you ping 192.168.1.254 (default address for router?).?

    How do you delete a network? When I try to do it under Network Connections, Delete is grayed out.

    Re: Can't Connect To Wireless Home Network

    Today I tried resetting the TCP/IP stack and WINSOCK entries to defualts in CMD and configuring a static IP address, but neither helped. 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?

    Considering some applications have internet access and some don't. I'd say check your firewall settings?

    Re: Can't Connect To Wireless Home Network

    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.

    Thank you for your help.
