How to get TP-Link TL-WN722N(EU) Ver 2.0 wifi dongle working on RPi 3 + NAVIO2

Navio / Edge Raspbian
1

I am using Rpi 3 + NAVIO2 (emlid-raspbian-20170922.img.xz)

I have alreay made some changes to the system get intwifi0 as AP using:

I have inserted TP-Link TL-WN722N(EU) Ver 2.0 wifi dongle expecting it to connect to the network that I have spcified in wpa_supplicant file. That config worked with intwifi0 before I changed it to be access point.

Hello.

From tutorial I found string nohook wpa_supplicant which does not allow connection using dhcpcd hooks.
Also I see that your device has name wlxd46e0e028dcf, not wlan0 as specified in /etc/network/interfaces. So you can try to change name to wlxd46e0e028dcf.

Thanks Alexey,

It seems that adding an entry for wlxd46e0e028dcf in interfaces file solved the problem. I didn’t have to remove no-hook wap_supplicant.

Regards,
