Re: [Cannot find device "wlan0"](/topic/1917/cannot-find-device-wlan0)

I hit the problem about wifi connection. When I boot up voxl2 board, "wlan0" doesn't exist. Also "eth0" and "usb0" doesn't exist. I did `qdl` and re-install `voxl-suite`. How to fix this problem?

@dlee What hardware are you using? Just a voxl2? or a whole drone?

@tom I'm using just a voxl2 board with microhard add-on board

@dlee So you shouldn't expect to see a `wlan0` as you have no WiFi add-on.

But you should expect to see either a `usb0` or `eth0` network interface from the Microhard modem enumerating. Did you run through the `voxl-configure-modem` steps for Microhard?
