Hi Richard, Thanks for your reply. I am not quite sure how to find out the driver for TL-WN722n on our ubuntu systems. We didn't have to actually install any driver on the beagle board (running Ubuntu 12.04 LTS omap) or the stand alone PC (Ubuntu 12.04) for our project. Can you assist in helping out to find the driver version for TL-WN722n wireless adapter to see if that is the reason.
Thanks.
