I run Ubuntu 13.10 (though on 13.04 situation was the same) on Thinkpad E125 laptop
I have very common problem – there were no WiFi after suspend. I've googled the problem and find solution that works perfectly – http://www.webupd8.org/2013/01/fix-wireless-or-wired-network-not.html – after following those recommendation I have probably 100 suspend/wake-up cycles – WiFi always worked
But this fix didn't affect hibernate – now I have 100% times not working wifi after hibernate. If after hibernate I go to suspend and back – wifi start working again.
Can some please advise the way to apply that patch to hibernate

Try
sudo killall NetworkManager, as suggested in Network devices unmanaged after resume from hibernation in Ubuntu Gnome 13.10 . It works fine for me!
