I've never seen more than two dhclients per interface so some weird edge case is being hit. I'm guessing the interface is thrashing between APs and that may be causing problems. What I really need is a trace of state transitions from the NIC. 80211watch and 80211debug in src/tools/tools/ath/ may be sufficent, though I'm not sure. If you can get me in, I'd be happy to come down and try to debug this myself since I live in Seattle. I'd certainly like my laptop to work when I'm trying to attend the show. :) -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
