Hey there,
I have been trying to get an external wireless card (TL-WN722N) working with my Nexus 6. I have tried countless different Nethunter/Android Versions and no solution of any of the threads I found regarding the topic has worked. Even if i get lsusb to register the card (which it never does by default), I simply cannot get it working as a wireless card.
If anyone has a Nexus 6 and got a wireless card working with it, I would greatly appreciate if you could share your Nethunter version and maybe additional steps you took to get the card working with me
