Ubuntu "Suspend" causes Wifi to go offline - Fixed

THE PROBLEM

When I would suspend my desktop, and come back the WIFI would no longer come online.

Here's what /var/log/syslog said:

Aug  6 17:56:12 jackal NetworkManager[1702]:  NetworkManager state is now DISCONNECTED
Aug  6 17:56:12 jackal NetworkManager[1702]:  (wlan0) supports 1 scan SSIDs
Aug  6 17:56:12 jackal NetworkManager[1702]:  (wlan0): supplicant interface state: starting -> ready
Aug  6 17:56:12 jackal NetworkManager[1702]:  (wlan0): device state change: unavailable -> disconnected (reason 'supplicant-available') [20 30 42]
Aug  6 17:56:12 jackal NetworkManager[1702]:  Trying to remove a non-existant call id.
Aug  6 17:56:12 jackal kernel: [22544.724766] r8712u: in r8711_wx_set_scan: bDriverStopped=1
Aug  6 17:56:12 jackal kernel: [22544.726297] r8712u: in r8711_wx_set_scan: bDriverStopped=1
Aug  6 17:56:12 jackal NetworkManager[1702]:  (wlan0): supplicant interface state: ready -> disconnected
Aug  6 17:56:12 jackal NetworkManager[1702]:  (wlan0) supports 1 scan SSIDs

THE FIX:
echo SUSPEND_MODULES=\"r8712u\" > /etc/pm/config.d/00sleep_module 
chmod +x /etc/pm/config.d/00sleep_module 
Now I can suspend my computer and come back and it returns online via wifi.
