I am attempting to use a Netgear A6100 wireless USB WIFI adapter on my Sony Vaio laptop with Ubuntu 14.04. The pre-installed wireless card lost bars of signal from my wifi router after installing Ubuntu, so I bought this USB wireless adapter to solve my connection issues.

Best Answer
Your device uses the rare and elusive driver 8812au. Please get a temporary wired ethernet or similar connection, open a terminal and do:
Your wireless should now be working.
When Update Manager installs a later linux-image, recompile:
Please retain the file and these instructions for that time.
We probably need to blacklist the internal driver to keep from interfering. Please tell me its driver from the command:
I will then edit this answer to provide instructions.
