Hello,
I'm experiencing a bug similar to this:
I tried with:
ethtool -s eth0 autoneg off speed 1000 duplex full
but if I disable autoneg the link becomes half duplex...

@rainkinz can you confirm that in your case the link stays full duplex after disabling autoneg? Are you on 23.05.03 ?
Hi @Documibozu,
It actually reports half duplex after doing autoneg off:

Thanks, after a reboot the AP seems to be stable with autoneg on.
Better hope it's not a cable fault 'cause it's a 15mt cable in a wall conduit

I doubt it is. I have tried several cables and get disconnects unless I do:
ethtool -s eth0 autoneg off speed 1000 duplex full
Which sadly seems to also set it to half duplex.
Sadly I can confirm that every 4-6 hours eth0 has a glitch and the cable is not the problem (tried with a proven cable of only 1mt length).
Now i'll try to test @rainkinz solution for some days and check if it's stable.
@rainkinz sorry to bother you again.
I don't want to giveup on full duplex and I'm doing some tests.
So a little question: are you powering your AP with POE or are you using the 12volt plug?
Thanks again
I'm having the same issue, NWA50AX-Pro eth0 goes down particularly when under load.
I can reliably reproduce this with iperf3 from a WiFi client to my firewall (that's directly connected to eth0).
This only occurs with traffic from a WiFi client through the AP to a device behind eth0.
Running iperf -R (reversing traffic flow, from firewall to client), there are no issues.
Running iperf (-R) from WiFi client to the AP itself (and vice versa) has no issues.
Running iperf (-R) from AP to firewall (and vice versa) has no issues either!
Only when traffic gets bridged AND flows out of eth0, the link on eth0 goes down.
Autonegotiation and Flow Control do not matter, what's actually fixing the issue is setting eth0 to Half Duplex. The NWA50AX-Pro does not support ethtool -A to disable flow control, but my firewall (intel NIC) does. Log on the Zyxel (note: Full Duplex but flow control off):

System load seems fine, 18% CPU usage by sys during iperf. Powered through 12VDC. I've set the TX queue length to 9999 on eth0 + br-lan (default: 1000) but that made no difference either.
What the?

How is this device powered?
Through the wall wart that came with the device (12V DC I assume)
Double check that it is the right one. It must be 12V supplying at least 2A.
Yes the supply says 12V 2A
Ok... good. Do you happen to have another adapter with the same specs? If so, try swapping to see if that improves the situation. A failing power adapter could result in what you are seeing.
In the meantime, let's take a look at the configuration:

-- snip only comments here --
I'll have to look for another power supply, but I doubt it's that since running concurrent iperfs client -> AP and AP -> firewall has no link drops.
Remove the last two lines here:
and delete this:
Reboot and try again.
The link still drops under load, config and full dmesg:

I ran some more tests.
Different power supply: same issue
Different ports on firewall: same issue
Switch between AP and firewall: rock solid, zero retries reported by iperf in a 10-minute run from wifi client to firewall
Laptop wired to AP's eth0: solid, but instead of link down the bandwidth drops from ~500Mbit/s to 100-200Mbit/s with 1000's of retries
With only these findings in mind I'd suspect the firewall to be the culprit, BUT iperf directly from AP to firewall as well as wired laptop to firewall run just fine at full gigabit speed, and then there are those retries when the 2nd laptop is connected to AP's LAN port.
Both the wired laptop and the switch auto-negotiate "1Gbps/Full - flow control rx/tx" with AP's eth0.
How can I troubleshoot this further?
I've never tried the stock firmware on the AP, maybe that's worth a shot?
Yes, it is. If the problem still manifests, it means it is either an issue with the AP hardware (such as power/thermal issues), or it is something upstream of the AP. If it doesn't show up, then it is something with OpenWrt (config or other issues).
Only to add my 2 cents.
It seems that this kind of problem are recurring with filogic soho poe AP with 2.5gb ports.
It's been documented also for netgear wax220
See here:
I suggest to add something in the wiki until the bug is investigated and mitigated.
Personally I can add that I had to return the zyxel for this problem.
I buyed a WAX220 but it was also affected under openwrt.
So I switched to the official firmware and it has been flawless!
Before wiki additions are made or bugs filed, it would be a good idea to know if the problem is OpenWrt specific or a function of the AP or the upstream network.
