Thread: Wireless USB dongle doesn't come up on system boot

-

hi,

have zotac zbox id41 machine, running ubuntu 11.04. bought wireless usb adapter (an edimax ew-7612uan), , have been trying make work ever since no success.

after having given on ubuntu 12.04 due shutdown hangs , such decided stay 11.04.

followed installation procedure of 8712u driver described in http://samiux.blogspot.com/2010/05/h...sb-dongle.html, blacklisted stock r8712u module, , had working while. other reasons removed network-manager , relying on /etc/network/interfaces define wlan1 interface (i don't have gdm running).

in case, works fine until next boot. kernel panic in dmesg, wlan1 not present, , led on dongle off. stays way until remove dongle , reinsert it. @ point interface comes , (i still stack traces in log though).

made sure put firmware http://www.tuxamito.com/rtl8192/rtl8192sfw.bin.gz in /lib/firmware/rtl8192su/, mentioned in other posts.

stack traces get:

any appreciated...

thanks,

rotem

what ath9k doing in lsmod? think interferes? should blacklisted? internal atheros doesn't work properly? may see:
code:
modinfo 8712u | grep firmware
