FYI 3.11 kernel landed in Ubuntu 13.10 development version, so this is now also fixed there without any tricks.
Ubuntu 13.04 is apparently getting a partial fix (not sure if it's enough, two patches were originally mentioned as being relevant) in its next kernel update (bug #1204666), and I've attached a patch to bug #971809 that would bring the other part there too if picked up by kernel stable release update team. ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1160188 Title: ATH9K wireless signal weak To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1160188/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
