My wireless adapter suddenly stopped working and when I run the manual diagnostics test the "Radio Test" fails. Do i need to replace the built in adapter, or is there another way to fix this?
My computer uses a Intel® PRO/Wireless 3945ABG (802.11a/b/g) adapter.

i figured out! the function (Fn) wireless key was turned off! for some reason this overrides the external switch!

thanks for the input Carl!

Check if there is a bios update for you laptop also uninstalling the driver and reinstalling. Also in the advanced settings check the radio is enabled. :)
