The last time I was able to connect to my Beaglebone Black Wireless
(using PuTTY), I powered it independently with a 5V battery. Afterward, I
turned it off, then used the USB to connect it to my laptop. The
beaglebone receives power, but my computer doesn't acknowledge the
connection. When I tried using independent power to ssh wirelessly, that
no longer worked either. If anyone has any idea how to help, please let
me know ASAP.
