Comment 13 for bug 1261753

I tried testing again with the newest Ubuntu liveCD, and at least in that environment it works correctly. And the wifi reconnects much more quickly too. It's looking more likely that this is some strange quirk of my system which has been upgraded a few times and may have some bad config hiding somewhere.

Is there an accepted way to reinstall Ubuntu on top of an existing installation, preserving at least the home directory? Otherwise I'll just flatten and reinstall and see if that fixes it.
