It appears that thee is a race involving the timing of the iwn (wlan0) coming up and the start of the wpa_supplicant. I see the interface start, and aesociate but immediately go down. dhclient starts, but fails. If I kill the interface (service netif stop wlan0) and manually start it (ifconfig wlan0 up), it comes up fine. I can then start the wpa_supplicant and dhclient to get it working. From this point, it remains stable. If I just let it bounce up and down, it usually will eventually come up, but it can take some time and, on occasion it simply fails to some up unless I intervene. wlans_iwn0="wlan0" ifconfig_wlan0="WPA SYNCDHCP" -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
