MBA Wi-Fi drivers for windows 7?

Hello Ladies and Gentlemen.

This is my first post here, have been lurking around for a while.

I've purchased the MBA, gotten it, installed Windows 7U x64. Everything's working properly, except one thing. The wireless internet. Or actually, it's working.. sometimes... and then... very slow... and gets disconnected all the time.

In Device manager / Network adapters the drivers for the NW-card is Broadcom 802.11n Network Adapter. That would be... wrong... right? I thought the MBA came with the "Airport Extreme Wireless Card (802.11b/g/n wireless Internet)".

Searched the old 'net, didn't find any answers or drivers, som here I am, asking... does anyone know anything regarding this?

Thanks in advance,
and cheers from Sweden!

Reinstalled drivers, and seem to be working now. Hmm... strange.

Well that makes this an official **** thread. Mods can close, if you want to..
