Did anyone try to connect an external USB WIFI card to UR? I am trying to connect TP-LINK TL-WN722N N, but I am not able to jump over installation of drivers.
If yes, what kind of card did you use?
If anybody have a solution for it, I will be pleased to read it.
You have to show us what you did that didn’t work. Anyway, this is Linux related question. Try looking for an answer in Linux forums.
On second thought, what are you trying to achieve? Connect more robots to AP or just connect your laptop to robot wirelessly? If it is the latter, then use a usb powered router like TL-WR902AC or TL-WR802N N300 Mini.
