I tried to post to this thread Hardware wireless switch has no effect after suspend and 13.10 upgrade for if I understand their question I am having the same problem, but the answer option won't work for.
After suspend, the wireless is disconnected and the only way to get it to reinitialize/be recognized is to do a full restart.
At first I thought it was my gnome-shell (for lock screen disappeared there with 13.10), but when I switched to the default Ubuntu it's still doing it and it's kinda driving me nuts for I have to reopen all my files and browsers/tabs/windows every time. I don't know how to show the terminal stuff the above asker shows, but it sounds like the same issue and it only started with 13.10 upgrade a few days ago.
Any help would be much appreciated!!! -- Thanks so much, ser.
