Well this is a strange one. I was fortunate enough to get good wireless connection with the drivers that shipped with the beta and strong signal in the next room. What is strange is even though I can browse the internet fine I have lost the ability to view network shares on any of my three machines in the next room \\server etc. So I worked a way around it. I would go to the bottom right task bar, right click the wireless icon and click wireless off, and then, wireless back on and I can browse my shares. Its a fault somewhere. It seems like it times out after a period of time. it is a hassle as sometimes I mirror files using a program called second copy and it will stop syncing halfway because the share disappears. Anyway just letting you developers know so it is fixed in the final hopefully. Now I have an intel notebook with decent specs but uses the older intel 2200bg wireless card. It works flawlessly all over our house with both XP and Vista but went back to XP as vista was too slow. Anyway I had a spare 60 gig 2.5inch drive and gave windows 7 a whirl. I noticed by a search on these forums that the 2200bg drivers in win 7 dont work. I tried several drivers that I knew to work under vista as I had them saved on my hard disk and dated as I do and then downloaded vista drivers too from their web site but still no internet access wirelessly. Lucky for me I just had to swap the drive back and the old set up was fine. I would run Win 7 on it when it comes out as it ran as well application wise as XP as far as I could tell but it has a lot of bugs and missing drivers and Dell won't be releasing any drivers for their older notebooks that's for sure.

Did you install the drivers in Windows Vista compatibility?
