Upon further analysis, it appears ath has an issue with APs that do not send beacons at 11b rates--and this is only obsernable with OpenBSD as the issue is not reproducible with the same card under Windows. Reconfiguring my Cisco AP to allow non-OFDM rates allows ath to see the SSIDs, but this also allows the AP to serve 11b clients, which is not desirable. Anyone else experiencing this?
