wireless networks not found

i have a fujitsu amilo 1718 laptop which will no longer connect to the router using wireless. two other pc's in the house can still access the internet wirelessly. the laptop itself can connect with an ethernet cable but when wireless it cannot find any networks. ~The first time it failed there were orange triangles next to the drivers for the network drivers in device manager. when i connected up via cable it automatically found new drivers but still no wireless networks can be found. i have tried uninstalling the network adaptor and reinstalling. i have reinstalled the drivers. the advanced tab for the network adaptor says it is working fine - the drivers are the most uptodate available. anyone got any ideas? thanks

Ugh, quite possibly you cards bunk... The card picks up no networks at all?

You should have some launch keys... Ones for the wlan... Try using that. Its odd the system recognizes the card, but can't use it.

Mite have to get a usb adapter, sucks but it works.
