I believe this is the same issue as:

Bananapi BPI R3 periodic disconnect all clients

Well, what a coincidence. Just when you commented and I thought 13 days of smooth operation would prove the issue has gone, it occurred again just 20min ago.

Bananapi BPI R3 periodic disconnect all (mtk_soc_eth: transmit queue 3 timed out)

Except I believe I’m the person to report it on the R4. Basicly, eventually, sometimes after an hour, sometimes after a week, I get

in the logs, and all networking stops working (I’ve attached a full dmesg). I retrieved these logs through the serial port. Many sources note that thermals may be an issue, but I’ve never seen temps over 75C…
