Mediatek has answered our prayers!!!

upgrade your MT7922 cards to driver version 3.4.2.1046 ASAP!!! , this driver version is the answer to all our prayers(who still have mediatek lol)

the best speed and latency values i have seen at a long range from this card

For context, my router is in corner of my living room and me sitting in my bedroom with doors closed , the distance is around 10m and the wifi(2.4g) band has to travel through 2 walls to get to me

with this in mind and my 50Mbps connection on normal AC router , i get 11Mbps download and 22Mbps upload speed and that too at freaking low idle and download latency.

on 2.4GHz band after 2 walls in a closed room 10m apart from normal AC router that has 50Mbps plan

ps. choose transmit power level = highest in your windows wifi adapter setting if u havent
