Ditching wpa_supplicant in favor of iwconfig (wireless tools port) solved my problems. Only downside is that I am unable to use WPA-PSK authentication. Maybe a future version of wpa_supplicant will work? Drew -- Be a Great Magician! Visit The Alchemist's Warehouse http://www.alchemistswarehouse.com -- [EMAIL PROTECTED] mailing list

Unlikely. ;-) I've used it a couple times and it always strikes me as much less stable than wireless-tools, even when authenticating to non-WEP networks. It would routinely fail to associate, even when wireless-tools worked effortlessly. I'd love to run WPA, just because it's better, but I'm unwilling to put up with wpa_supplicant.
