A few days my wireless connection on my computer stopped working. It is saying limited or no connectivety. We have a linksys router with: 1 desktop hardwired, and 2 toshiba connecting wirelessly. The desktop and one of the laptops are connecting fine. The same day I had another laptop very similar model to the one that stopped working and it would not connect at my house and it usually does. After the person took it home it connected on their linksys router at home. Ive tried to hardwire my pc from the router and also tried from the modem and it didnt work. I have tried renewing the ip address, assigning a static address 192.168.1.149 . That wouldn't work. The Wireless Zero Config and the DCHP services are on. I read many topics on this in other forums and tried many of the things said and none of them worked. Almost forgot, I restored my computer with the restore cd and it still does the exact same thing.

Okay well we got an wireless g card from an older computer tried using that on the computer that wouldn't connect and it still wont work. It does the same thing.

replace your router did you set the router back to factory default with the little reset button on the back of it??
