ARMBIAN 5.38 stable Ubuntu 16.04.3 LTS 3.4.113-sun8i
Shows: 

Bus 004 Device 002: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter
But ifconfig -a show only eth0 adapter. No ra0 link

 

I've tried 

sudo apt-add-repository ppa:thopiekar/mt7601
sudo apt-get update
sudo apt-get install mt7601-sta-dkms

 

But still no results. 

 

 

 

 

 

 

On a NanoPi Neo2 I got the mainline kernel

ARMBIAN 5.38.180128 nightly Debian GNU/Linux 9 (stretch) 4.14.15-sunxi64

 

and there the mt7601 is available without a special repository:

root@nanopineo2:~# find / -name mt7601*
/lib/modules/4.14.15-sunxi64/kernel/drivers/net/wireless/mediatek/mt7601u
/lib/modules/4.14.15-sunxi64/kernel/drivers/net/wireless/mediatek/mt7601u/mt7601u.ko
/lib/firmware/mt7601u.bin
/lib/firmware/mt7601.bin
 

Did you try to

modprobe mt7601

and then

ifconfig wlan0 up

 

or create a WiFi connection inside of nmtui?

I've installed system with 4x kernel and now it works. 

 

Thank you!
