I have a Dell Dimension 9200, which was connecting to the Internet via Netgear WG111v2 wireless USB adapter. I also have a Dell Insprion 1501 using an Internal network card no problems. Both running Windows XP. Router is BT Voyager 2091. After doing a Windows Update, I had problems with internet connectivity (limited or no connectivity). Reinstalled the Netgear drivers (via laptop connection), no joy. Tried manually setting up IP address, and it could see the router, but would not bring up the Internet. Did a system restore to just before the Windows Update, and Internet came back, but then had problems with itunes/quicktime. A knowledgeable friend thought it best then to do the Windows Update, and the Internet connection again disappeared, but now I cannot do a system restore. Am able to connect to router with an Ethernet cable. Thought maybe the Netgear was faulty, so I've now installed a Belkin Wireless G+ desktop card. Initially this found the router, but with limited or no connectivity. After a reboot, the Belkin cannot even see the router (cmd line says Media disconnected, but after complete reinstall of Belkin using latest software from Belkin website, no joy). In desperation I've restarted the Netgear, which comes up with 'Limited or no connectivity still'. ipconfig /all shown below: Host name: Arthur Primary DNS Suffix - Node Type - Unknown IP Routing Enabled - No WINS Proxy Enabled - No Ethernet adapter Wireless Network Connection 3: Media state - Media Disconnected Description - Belkin 802.11g Network Adapter Physical address - 00-17-3F-86-7F-45 Ethernet adapter Wireless Network Connection 2: Connection specific DNS suffix - Description - Netgear WG111v2 54Mbps Wireless USB 2.0 Adapter #2 Physical adreess - 00-0F-B5-CD-16-02 Dhcp enabled - Yes Autoconfiguration Enabled - Yes Autoconfiguration IP Address - 169.254.79.67 Subnet mask - 255.255.0.0 Default gateway - 169.254.79.567 If I try to ping the router on 192.168.1.1 the request times out.

This morning I connected the Wii to the router wirelessly - no problem. Any suggestions greatly appreciated. Sorry for the lengthy post.
