Description

I have two types of mt76 routers mir3g and mi4a gigabit (mt7612) and redmi ac2100 and dlink dir878 (mt7615). Certain clients e.g. mitv stick have very slow download ~3mbps when connected to mt7615 devices, but good speed > 300mbps when connected to mt7612 devices.. I tried same frequencies same channel width (80 mhz) etc etc

this happens on master openwrt and on 21.02

Any info i can send to help debug?
