I tried a few other things that what I've listed below, but none of it worked. This is a dual boot machine - I also run Windows XP, and don't have any issues with wireless on that OS. Any clues would be appreciated. # uname -a FreeBSD grimsqueaker.pigfarm.org 7.2-RELEASE FreeBSD 7.2-RELEASE #0: Fri May 1 07:18:07 UTC 2009 root@driscoll.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 First, in /var/log/messages, I found the following: Sep 13 15:09:23 grimsqueaker kernel: wpi0: device timeout Sep 13 15:09:23 grimsqueaker kernel: wpi0: link state changed to DOWN Sep 13 15:09:24 grimsqueaker kernel: wpi0: could not set power mode Sep 13 15:09:24 grimsqueaker kernel: wpi0: device config failed So I tried stopping and starting netif: # /etc/rc.d/netif stop Stopping network:wpa_supplicant not running?
