Comment 91 for bug 1286552

Finally found a fix that worked for me: http://askubuntu.com/a/368836

Also, at http://ubuntuforums.org/showthread.php?t=2218043, there was the following extra line in wakenet.sh:
pkill -f wpa_supplicant
...but I found I didn't need that. (But I'm posting that here in case someone else will need it.)
