Sorry about the trouble you are having with the Wifi. The thing about Wifi is that there are many factors that can affect it. Probably the quickest fix is if you pick up an adapter with a little more range and an external antenna. This is the one I've been using and I haven't seen any issues with it. http://www.amazon.com/gp/product/B00JDVRCI0?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00

The Beaglebone Black has a known issue with Wifi and interference from the HDMI port. They recommend either disabling the HDMi port or getting an adapter with an external antenna. I thought I had disabled the HDMI port in the Kernel tree. I can double check for you.
