Just dusted off my BBB and it’s struggling to get wifi going - it was working fine a few months back.
I have an Edimax usb wifi dongle in a 2A powered USB hub.
ifconfig shows:
wlan0 Link encap:Ethernet HWaddr 74:DA:38:0C:C7:8B
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
lsmod shows:

So the driver appears to be there.
I have double checked the wifi.config
/usr/lib/connman/test/test-connman services shows my hub is there.
dmesg is showing this though:
