For those on Ubuntu 13.10 with kernel 3.11, problem is caused by changes
to rt2x00pci kernel module:
https://bugzilla.kernel.org/show_bug.cgi?id=61621. Patch has been
submitted to kernel developers:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/rt2x00/rt2x00pci.c?id=9483f40d8d01918b399b4e24d0c1111db0afffeb.
To get it to work before those changes are included in Ubuntu, rebuild
the kernel with the patch:
