OK, *another* follow-up. Installed wicd instead of network-manager. That works!
Reverted kernel back to 3.2.0-25 (i.e. stock), nohwcrypt is 0 (off). The background scanning and the ath9k module are at the root of this problem, installing wicd is a work around. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773154 Title: Atheros AR9285 extremely slow & unstable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/773154/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
