Have you tried the 21.02 release version?

sanitariu commented 3 years ago

I am using master branch - r17486-cdc646c032 From 3-4 days behind. I will update to latest again.... but there are no changes i think.

Please try updating to mt76 HEAD. A manual update in the mt76's openwrt package is needed at the moment.

Now at r18070-49f615022c. Mediatek 7628 does not crash but it looses wifi on heavy traffic like torrent. It is easy to test. Just connect wifi to the router. Grab some torrent and do speeds like 5-8MB/s via wifi. After 5-10 minutes you will be disconnected. WIFI ssid is not discoverable for 1 minute then you can reconnect again. There is nothing in the log files. Still lot of work must be done for mediatek.
