LSP outdated

[jellabi]

Hello,

I just bought a new computer, with a giga-byte EP35-DS3R motherboard with an on-board network card. I connect to the internet through a pair of home adapters (modem -> router -> UTP cable to adapter 1 -> via the electricity network in my house to adapter 2 -> UTP cable to PC. Normally my internet just works fine, but yesterday i got the error that my LSP was outdated and i couldnt get on the internet anymore. So i connected a wireless adapter to my desktop, but also with that adapter, the internet wouldn't work on my desktop. The internet connection however is fine, cause we have a windows xp running on it too, and the internet works fine there. It's only my windows vista which is getting this problem. As anti-virus i have Nod32. Im really desperate cause really nothing works to fix this :S

Thanks already for the person(s) who are going to help me,
