I have wireless internet setup and it quit working a few weeks ago. No settings were changed.
Hardwire works fine on both laptop and PC so the network adapters are fine.

I have a Netgear 54mbps wireless router.

Try to check the router`s configuration 192.168.1.1 or 2. If you are ussing a modem, make ssure it is being set to bridge mode. In the router just secure the wepkey and i belive it should well set your configuration`s.
