After upgrading from a previous version (eg: 12.04 to 12.10) it stops working. Tries to connect many times without correctly finishing connection. Appears connected on Network Manager but does not receive Internet. Connects and disconnects continuously every X amount of seconds. Fails when installed via Additional Drivers / Additional Hardware (Link 3 Below). 
Creates huge log reports trying to correctly configure or connect. 
System freezes completely (You can only press Reboot/Power button) (Link 1 Below). Crashes system with dmesg errors in log (Link 1 Below). Stops any receiving/transmitting traffic (Needs reboot to temporarily fix). Keeps asking for password even on cases where AP does not have any. Stops searching for other devices (Does not see any other device). Connections timeout after several minutes or hours. Common problems that will be solved (Apart from drivers not installing) are: After you follow this guide, you will NEED to test your wireless connection for at least 2 hours (I actually recommend 8 hours) with another device in either Ad-Hoc Mode, Infrastructure Mode or Both.
