How to install driver for RTL8188CUS Wireless adaptor?
I recently purchased an RTL8188CUS wireless usb adaptor which does not seem to work out of the box.
Ubuntu 12.04 32bit Network manager knows it's there and can detect available Networks however it is incapable of connecting.
A driver download for this device is available from here
Unfortunately I have no idea how to install this driver.
If someone could tell me the necessary commands I would be most grateful.

In Ubuntu you should never have to deal with drivers. If you do, then it's a bug (or you should upgrade). In this case, I think it's LP Bug #852190. Specifically, avoid downloading drivers from 3rd party websites - it's not easy usually, potentially insecure and usually not targeted towards Ubuntu.
Just do:
sudo apt-get install linux-backports-modules-cw-3.6-precise-generic
and reboot. This newer so-called compat-wireless
driver is provided as a package in Ubuntu for your convenience.
You would have come to this step also when following my guide:
