Looking at the changes since 19.07.3, I would guess the regression comes from https://git.openwrt.org/7ac454014a11347887323a131415ac7032d53546

You can try reverting this commit on top of the openwrt-19.07, and if this works, contact the author.

sipples:

I'm seeing this same problem with OpenWrt 19.07.4 on an Asus RT-N56U (first hardware revision) wireless router. The problem does not occur with 19.07.3. It's the same pattern that Sergio observed, with error messages in the kernel log from mtk_soc_eth. Specifically, the 1000BASE-T/full duplex Ethernet connection between the WAN port and the upstream fiber Internet box periodically resets (in the Asus RT-N56U), with service interruptions lasting several seconds at least, typically causing Web browsing and streaming media timeouts on the wireless client side. I tried a cable swap to see if that'd help, but it didn't.

Sergio, have you heard anything from the author of that patch? Any additional troubleshooting beyond what I can confirm so far? It doesn't seem like a well considered patch from the author's description.

I can confirm. After rolling back the commit, the problem does not recur.

I can confirm the same - had identical problem with my Mi Wifi Mini - reverting 7ac4540 and rebuilding 19.07.4 and so far it seems like no further occurences.

I can confirm the same behavior with my ASUS_RT-N56U. 19.07.4 is bad 19.07.3 is good so far.

The commit has been reverted. Next 19.07 release will not have the issue.

The Asus RT-AC51U also affected.

EDIT: thx 19.07.5 works fine
