Yes, I'm also experiencing similar problems. The problems seem to happen also with different wireless cards and without wep. They were reported by Johann Hugo on 14th in an email titled "ath hostap - clients assosiated, but no comms" too. Another problem with WiFi which Johann reported long time ago is that bridging on atheros (only?) AP works really bad. I get very varying ping response (50 - inf. ms). Sometimes it seems the packets get queued somewhere - after some time I receive several replies at once. I tried to debug it a little but didn't get anywhere. I will try some more.
