Try re-installing the drivers and see if this work out.

What items are between the wlan and the router. If there is interference you will not be able to pick up any signals.

Did you check the wireless devices that you use? Wireless modems/routers might not be funtioning properly, or may they are not properly configured.

Maybe re-configure your router, click the reset button at the back of your device and re-format everything then give it a go.It could be that just this computer is not configured correctly to meet your routers needs.
