[Bug 1252121] Re: missing PrepareForSleep signal after resuming, causing networking to stay disabled

[Philipp Keck]

A reinstallation might help. Even though the bug has not been fixed for the new LTS version (....), a fresh installation might help. I didn't do much testing because I uninstalled Ubuntu to free up my SSD space for Windows (which runs rather stable and doesn't give a whole bunch of error messages after login), but for 10 minutes I tested Ubuntu 14.04 from a USB stick, and it didn't have the problem. So maybe if you install it, it won't have the problem either.
However, I do realize that reinstalling the entire OS might not be something you want to do - that's why I'm on Windows now.
