The patch that was incorporated into linux-backports-modules is not a solution, only a workaround. And it doesn't solve the issues described as stated by me and many others in the comments.
Please have a look at this kernel bug where a solution is being proposed http://bugzilla.kernel.org/show_bug.cgi?id=14267 (Disassociating atheros wlan). Quoting from the proposed bug fix: "I did a bisect yesterday on this, and the results seemed to have worked over here by reverting: 75e6c3b72b3ab01c47629f3fbd0fed4e6550bf3a cfg80211: lower dynamic PS timeout to 100ms". Hopefully this should provide a real solution. ** Bug watch added: Linux Kernel Bug Tracker #14267 http://bugzilla.kernel.org/show_bug.cgi?id=14267 -- 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
