After connecting the wireless adapter we run the following command:

 

lsusb

 

the output is

 

Bus 004 Device 003: ID 148f:7601 Ralink Technology, Corp.
 

Trying to install armbian driver  (Linux nanopim1 3.4.113-sun8i #18 SMP PREEMPT  armv7l GNU/Linux) for lb-link model: wn155a "MTK7601 chipset" wireless adapter (150Mbps) using the following commands:

 

sudo apt-get install linux-headers-generic build-essential git

sudo apt-get install git

git clone https://github.com/flexiti/mt7601.git

cd mt7601

make clean

make

sudo make install

sudo mkdir -p /etc/Wireless/RT2870STA/

sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/

sudo modprobe mt7601Usta

 

the output of the last command is 

 

modprobe: ERROR: could not insert 'mt7601Usta': Exec format error
 

what should we do?

is MT7601U the same as MTK7601? or do we need another driver?

This module works on kernel 4.19.y ... Better use that one. You can also try with hints from this script https://github.com/armbian/build/blob/sunxi-4.18/packages/extras/mt7601.sh

THANKS, WE USED THE SCRIPT YOU RECOMMENDED AND OUR PROBLEM WAS SOLVED.
