Access Conn. in Win 7 - can't specify 802.11a/b, g, or n

[albo]

Hi Folks,

Just upgraded my T400 to Win 7 x64. I installed access connections, but it seems that I'm unable to specify in a connection whether the wifi adapter should use 802.11a/b, g or n. I need to specify this sometimes, as certain protocols have flaky connections where I work (for some reason). Any ideas? I remember being able to specify this on the same machine, but using XP.

thanks,
allie
