It eventually associates with the wireless router (dlink, unencrypted) after 5 or 10 minutes, or after poking it with an ifdown/ifup wlan0. Without the following patch, association occurs by the time dhclient starts looking for an IP address for my machine. mike@mini:~/net-next-2.6$ cat wireless-regression.txt 77fdaa12cea26c204cc12c312fe40bc0f3dcdfd8 is first bad commit commit 77fdaa12cea26c204cc12c312fe40bc0f3dcdfd8 Author: Johannes Berg Date: Tue Jul 7 03:45:17 2009 +0200 mac80211: rework MLME for multiple authentications The system is a mini-mac, and the wireless card is using the ath5k driver: 02:00.0 Ethernet controller: Atheros Communications Inc.
