Firmware upgraded
lede-17.01.2-ramips-mt7688-omega2-squashfs-sysupgrade.bin

Problem
Wifi does work but does it very badly. Constant packet lost, pings >3000ms to device located near by and so on. Download speed ~18kB in compare with 6-7Mb with original image

Donno of this LEDE image includes proprietary wifi driver for MT7688AN chip or not. Seems like it is a reason
