mt7603 lose internet connection

[9000000]

mt7603 still fails to watch a video file that we fast forward many times it will lose internet connection

All versions of openwrt 18 and 19 I use have this error My router xiaomi r3g v1

[JFtico]

Try the latest snapshot, there were some significant WiFi fixes the recent month.

[9000000]

I have tried many times but still got an error

[Openwrtfunboy]

Yes, in snapshot from 8 APR i have same. Also have on latest stable Openwrt.

I thought it was better, but just looked the kernel logs for a unit with 28 days uptime, running on snapshot r12529-228bb84744
This unit is used strictly as an Access Point. So no dnsmasq, or other stuff loading it. It recovers, as the users have not complained. but obviously something is bad.

Context: primary AP for home with two tech workers, laptops and iPhones, a couple of Android tablets and test phones. IoT stuff (a dozen, but nothing heavy duty, no cameras) All other gear is hard-wired (via a sperate switch). Hardware is ZBT-WE3526

Here is the full kernel log. Looks like several 7603 re-starts, but also other proc oops as well.
