I have also two Netgear R6220 and they have the same problem with alot of interrupt errors. MediaTek MT7621 ver:1 eco:3 Netgear R6220 OpenWrt SNAPSHOT r15469-425e392466 / LuCI Master git-21.009.66148-9e4391e

Interrupt errors increase when I check wifi speed connection using Meteor application on android smartphone.

I saw constantly growing interrupt errors across the entire 19.07.x releases on a ZBT-WE3525 (7621/7612/7603). Hoping for something better from 21.02, I built one on on 4/15/21, and while many aspects have improved, power being the most noticeable, the proc/interrupt errors continue to grow. And stations get into connect/disconnect loops if the strength is marginal. Errors seem to climb mostly from 5Ghz radio activity, as the same box running as a router-only (no wifi) sees single digits worth of errors after a week.
