wlan not working after reboot Atheros AR9001U


i couldn’t figure out a way to make this wlan-chipset working.
The strange thing: initially after configuring it in the gui it will work - but will stop functioning after a reboot.

putting the SSID and password in quotes won’t work either (see other post)

lsusb: pastebin.com/kHWGsGDe
interfaces: pastebin.com/6BQDJbWE
ifconfig -a: pastebin.com/wLUkWA31
dmesg: pastebin.com/eKMmbhnw

i tried it with a different wifi, still no success.
pimusicbox works with the chipset.

any ideas? i’d really like to see volumio working :slight_smile:
