Wireless slow to connect - used to be fast

[netpenthe]

Hi

When I installed Win 7 RC on my X200s it was initially really fast to connect to wireless networks/Internet.

Now it takes around 3-4 minutes, it gets stuck as "Limited Access", then "Identifying.." before finally giving me Internet Access

I'm using the Windows networking (not Access Connections)

I know it could be fast (like 20seconds) as this was one of the things that most impressed me about Win 7 (it was almost as fast coming up as a macbook)..

Its frustrating now

Any ideas? i'm guessing some anti virus or something is slowing it down (i've only got the Windows Defender or whatever its called installed)

Thanks in advance

Jon
