Also using backport-modules on jaunty. Seems, the problem is when re-associating takes more than 2 seconds. http://thread.gmane.org/gmane.linux.kernel.wireless.general/31690/focus=31691 talks a lot about this bug, and i think changing tha timeout from 2 to 10 seconds as a workaround might be a good interims solution, until a proper fix lands in the wireless-git tree. -- mac80211: WLAN losing connection: No ProbeResp https://bugs.launchpad.net/bugs/200500 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
