I've recently installed 22.03.0 on my Netgear R6220 and immediately after installation I noticed that I can't use SSH over Wifi.
The issue is the same as this: [SOLVED] SSH over wifi stops working on RT3200/E8450 with 22.03.0-rc6 and fixed here: https://github.com/openwrt/mt76/commit/5ec78e1ec43d1e39edfea1efb9fd4541fa004af0
In my case, drops start so soon after connecting, I can barely run a single command.
I'm posting this because I'm not sure the above fix made it to MT7621 / other devices. I've tried understanding where the commit from the second link went, but I wasn't successful. Could someone shed some light?
