11b is not preferred. AP selection is done according to various criteria like
compatibility (e.g. station wants WEP and AP is using WEP). If you do
ifconfig ath0 debug
you will see what's going on. The AP with the best rssi is typically
selected. To lock on to a particular AP you have to steer the algorithm by
constraining the choices. This issue comes up often--it would be great if
there were a connection between the 802.11 layer and a user app that would
help users select an AP based on scan results but I don't know of anything
like this for *bsd. Windows users are used to have a "site survey" app that
does a scan and presents a list of AP's to choose.
