It would appear that the machine is not enumerating your USB adapter as
a WLAN card (or did you just snip that detail out?). So first thing to
do is ensure you've got the correct realtek drivers built / loaded,
based on the internal Realtek chipset it's actually using. I didn't
happen to see that info in the dmesg output (just that it was some
802.11n card). It might show up in 'lsusb' though.

Note - as far as I am aware, most (all) of Realtek's drivers will
require a bit of compiling to get the dkms module(s). From the last
time I used a Realtek card, I think I got the driver from the 'lwfinger'
github repo.
