Point is, down the road wlan0 will be created, with 2 things following 1. start wpa_supplicant if it is configured in rc.conf 2. create an event for devd which will again invoke pccard_ether for wlan0 So basically we have 2 instances of pccard_ether started, one for ath0 and one for wlan0. create ath0 -> devd (new interface ath0) -> pccard_ether -> create wlan0 (*) -> start wpa_supplicant (*) devd (new interface wlan0) -> pccard_ether -> start wpa_supplicant Hope that makes it a bit clearer. -- Bernhard
