Ubuntu 13.10 does not exhibit the behaviour I describe above from 13.04. The kernel I'm now running is from a copy of Ubuntu 13.10 which was installed fresh today and is fully-updated as of a few hours ago. uname -r reports the kernel is 3.11.0-13-generic which is from Ubuntu's standard "saucy" repositories. I believe the issue as originally reported only manifested itself when the wifi adapter (an integrated Broadcom BCM4331 802.11a/b/g/n) was set to enabled in the network-manager AND associated with a wireless network. Just being enabled was not enough to cause the problem, IIRC, but the problem immediately arose as soon as the wifi was associated with a base-station. lspci on Ubuntu 13.10 currently reports that the Broadcom wifi is using the wl kernel module, and Ubuntu's "Software & Updates applet -> Additional Drivers" says the wifi is using the bcmwl-kernel-source proprietary package. packages.ubuntu.com shows that the bcmwl-kernel-source has had a version change between 13.04 and 13.10 releases of Ubuntu, which may account for the different behaviour: * raring (13.04): 6.20.155.1+bdcom-0ubuntu6 * saucy (13.10): 6.30.223.141+bdcom-0ubuntu1</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
