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.
Get a 3.3V USB serial cable. You will be glad you did. This should be your #1 tool priority.

That is an outrageous price for a knockoff copy, but yes.
