[LEDE-DEV] [OpenWrt-Devel] MT7620A WiFi issue - with a twist!

[Juergen Kimmel]

Hello everyone,
I'm in the same boat struggeling with  mt7620a WiFi performance,
namely with the device called   ZBT APE522ii.
Stock firmware based on Openwrt (has no version number) has no issues
concerning wifi performance.

Because I`m focussing on a mesh solution,  I tested Openwrt/Lede based
qMp (qmp.cat) but having the same issues described here.
IMHO there must be different drivers to be used. My skills are not at
all  sufficient to clear where the difference could be.
So help is very much appreciated.
