Well this is embarrassing. So not only does the last one you made work, but I re-tested the stock kernels and they now work as well:
Linux reech 3.2.0-57-generic #87-Ubuntu SMP Tue Nov 12 21:35:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Linux reech 3.2.0-56-generic #86-Ubuntu SMP Wed Oct 23 09:20:45 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Linux reech 3.2.0-56-generic #86-Ubuntu SMP Wed Oct 23 09:20:45 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux I don't really understand what could have happened, it was definitely repeatable behaviour (did it several times) with the original report. Thanks anyway, and sorry for any time wasting that's due to anything I should have done differently. Guess you can close this now. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1255022 Title: Wireless networking unavailable/does not work Status in “linux” package in Ubuntu: Confirmed Bug description: After an upgrade to the linux-image-3.2.0-56-generic kernel on Ubuntu 12.04.3 LTS, my laptop had no wifi. No lights, nothing in network manager to even acknowledge the existance of a wireless capability. On rebooting into the previous kernel linux-image-3.2.0-55-generic it works again (and thus I am able to report this!).
