What's the make and model of your 802.11b access point?
Other have suggested the "g-only" mode as a potential culprit. It's
possible but as I recall, the access point is what determines if it's
going to play g, b, or both, not the client. Dunno, but it's worth
checking.

I like to troubleshoot things by substitution. Some questions:
1. Are you using Windoze Wireless Zero Config as a client/driver or
are you using the Atheros monitor program? Windoze WZC has a feature
in the advanced settings that says something like "connect to any
available access point". That may not be the cause but it certainly
will not help if it's checked. Also, edit the preferred order of
SSID's that it will try to connect. If it's really full of other
SSID's and you're is at the bottom, it may never get around to
connecting.
2. It's not clear if you are able to connect to your 802.11b access
point in the absense of 802.11g traffic. Is this the case? If not,
then it may be a simple WEP or WPA key mismatch that's causing the
client radio to look for alternative access points. Can you connect
at all? If not, have you tried connecting to your 802.11b access
point with another wireless client? If it's misconfigured or
defective, nothing will connect.
3. Can your client radio connect to any of the other 802.11g access
points that it hears? I'm trying to determine if the Atheros card and
driver are actually functional
4. I've seen flakey RADIUS authentication servers do something
vaguely similar when AP can't find the authentication server. Are you
using RADIUS?

You'll have to wait for 802.11r to be released, which will do that in
addition to fast roaming and switching between access points.
