I'm running Gentoo amd64 on a Toshiba Satellite C655 with an Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01). For some strange reason, if net.wlan0 has some trouble starting correctly (e.g. I'm not in range of my network), i can't bring wlan0 up directly. Attempting to do so results in a slew of SIOCSIFFLAGS: Unknown Error 132s. Running
rfkill block all
rfkill unblock all
seems to fix the problem, but i have no idea why. Perhaps someone could shed some light on my situation?
