Wireless lan card

Try turning off the router for 30 secs, then power it up again.
Then try connecting a LAN cable from the computer to the router and see if you can connect to the Internet.
If you can connect to the Internet then -
With the LAN cable open a browser and type in the configuration URL and check the Wireless settings, then check and/or the wireless card settings (it should have the router's SSID and encryption settings etc.)
Also install the latest wireless card driver.
Then test the wireless and Internet connection. If this doesn't work -
Next connect the computer with a LAN cable to the cable or DSL modem to see if you can connect to the Internet.
If you cannot get an Internet connection with the LAN cable, contact your ISP and get them to test the connection to your modem.
If the modem and Internet is OK and you still cannot get a wireless connection then the problem could be a faulty wireless router.

I assume you are following my instructions.
Did you connect the LAN cable from the DSL or cable modem to the WAN or Internet port on the wireless router?
To test if the modem is working properly, connect the LAN cable from the modem to the LAN network card on a computer and see if you can access the Internet.
If if doesn't connect to the Internet, contact your ISP and they can check the connection to your modem to determine if it is working properly.

Try restoring the Belkin back to the factory default by powering up the Belkin and pressing the RESET button on the back of the Belkin for 7 secs. Then connect a LAN cable from the computer to the Belkin, open IE browser and type the configuration IP address and configure the wireless settings ie. SSID, encryption etc. The computer wireless cards will need to be configured with the Belkin wireless settings to allow them to communicate with the Belkin.

Check the Device Manager to see if the Wireless LAN device is working and enabled. If not reinstall the Wireless LAN driver.
If the Wireless LAN is OK and enabled then sometimes when you bootup the Wireless LAN card doesn't get an IP address from the wireless router. This usually has a red X on the wireless connection icon and sometime you get an error message "Limited or no connection".
To get the router to issue the wireless LAN card with a new IP address, righr click on the Wireless icon and click on Repair.
You can also power down the router wait 15secs and power up the router again then reboot the computer.
If it still doesn't work you could have a faulty wireless card, see it your friendly computer shop can test it for you.

go into the device manager and uninstall the wireless adapter. Then click scan for hardware changes and let windows resinstall it. It sounds like a corrupt driver. Before doing so make sure you didnt hit the wireless button that shuts off the connection on the computer. :)

Check this Tip for an overview

1. Connect your PC to your router using LAN Cable: be sure you can browse internet
2. If you cannot browse check router config with your ISP
   
3. Connect to your router using IP address you find for gateway in Network status
4. Configure your router wireless section to match with your PC card
5. Start removing security, broadcast radio signal, create a simple SSID as network name
6. Check if router network is seen by your PC card (when you disconnect the LAN cable and activate the wireless card)
7. If connection is established ( near the router) try different location
8. Reconnect cable and reconfig adding security protocol (WPA-PSK recommended) use parameters compatible with your lan card
   

see if there is a updated wireless driver for your wan!

check the ettings on the router have not been altered. the chance of 2 wireless cards failing in the same time, on different pcs is very small, more likely the settings that allow connection in the router, the item common to both, have been changed, reinstalling the router has no effect on user settings,
WEP, encryption, MAC controls are all possible suspects, if there has been any change
lock down the router,
many wireless networks are unsecured at the router so that any person driving past can access your router and alter it, default security settings should be changed the day you turn it on
