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.
Bus 001 Device 005: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN
