I am running my BBB on external power (one recommend) have a RL usb wifi connected to the USB port (direct, no hub).
I can see the device with an ifconfig -a as follows:
`

My /etc/network/interface has the following (where ssidname and password have the actual names
`
allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
wpa-ssid actualssidname
wpa-psk password
`
When I boot (with wired ethernet or not), the wifi is not configured. I can add a static route in the interface file, and it comes up on boot (I can then ping it on the wired, or wireless ips). I cannot ssh into the wireless one however (which would be because I didn’t change the default route I would assume).
So I believe the wireless adapter is capable of working (given I can configure a static ip). What I would like to have is the wireless be dhcp, and if no wired ethernet, have the wifi be the default route and be able to ssh etc via that means.
Is there something or some file I should modify?
I believe the following is the relevant dmseg:
