It looks like the problem starts after a suspend/resume as Matt Behrens said in comment #5.
If after a suspend/resume, I press Fn + F2 (disables the wifi) on my netbook and press again Fn+F2 (enables the wifi) the problem disappears. -- ath9k disassociates/reassociates a lot https://bugs.launchpad.net/bugs/414560 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
