Sorry for posting this often, but for my USB device the solution turned out to be even simpler than what I described before:
(1) Type into terminal: gksu gedit /etc/modprobe.d/blacklist.conf (2) Add those to lines to the file and save blacklist arusb_lnx blacklist ar9170usb (3) Reboot your system This is all that is needed to make your usb networking device work if you experience this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721449 Title: slow wifi (atheros driver issue) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
