TP-LINK AC450 Archer T1U Wireless on Ubuntu

Hi there

I would greatly appreciate if anyone could help me. I have bought this http://www.canadacomputers.com/product_info.php?cPath=27_1048_1049&item_id=089252 usb wireless adapter.

I have been using Ubuntu 14.04 for my main driver. Therefore, I installed the drivers http://www.tplink.ca/en/download/Archer-T1U.html#Driver provided by the TP-LINK site for Linux. The problem is that when the drivers are installed and the wireless is set. It only works for 1-2 mins and then the whole system hangs. I have tested it in two different Ubuntu installations but with same issue. It hangs the OS.

Let me know if there is any thing else I need to try or should I buy some other AC wireless adapter good for linux?
