Question : Vista Home wireless adapter connecting only with limitted access

My Toshiba laptop is not connecting fully to the router suddenly. It used to work just fine. The other laptop is connecting, so the router is not the problem. Vista says "connected with limitted access". I found this hotfix http://support.microsoft.com/kb/930517, but there is no x86 version for it. In the same knowledge article they recommend to download the service pack 2, but MS' website is quite confusing.

Thanks
