Yes, this may be expected behavior, when LAN devices go down and come up again.
I would like to know if ethernet links go down unexpected, especially when the WAN or LAN uplink port goes down. Is it a problem
When unexpected LAN connection drops happen more often and disturb services we need more debug logs.
When you see these logs in your router, do you know if the device connected to that LAN port is down or up?
AFAIK E8450 do not bring down any ports. It only senses whether the other end connected to its port is up or down. When it boots, OpenWrt will bring up all ports as configured by user. After that it doesn't actively managed the ports.
Do you see any weird behaviour (e.g. no traffic flowing) for your router?
The device is up in my case and I can't see the cause for the disconnect.
I have no traffic flow log since it's only a few seconds.
I can also confirm that latest master builds are causing the wireless interfaces to become inaccessible after a while. Sometimes very soon after updating the firmware, but sometimes after several days of continuous working without issues. The device is used as a classic router (PPPoE WAN connection) but I am using only wireless devices so I enabled WED. After the latest event I was able to connect to the Ethernet interface and downloaded the log:

Latest messages are during my Ethernet connection for debugging the router, but I left them to see the subsequent timeouts.
I also remember that I've tested a more recent mt76 build than the one used until yesterday by openwrt and noticed that WED was not active. I saw now that they recently updated the mt76 build, will test soon.
Well, my E8450 is happily purring away for more than 10 days now. I've setup a cronjob to detect issues and force a kernel panic so that I can capture the kernel logs. Will know if mine is the same as yours once I get my hands on the logs.
Oh no, my fears were confirmed, with latest mt76 wed is not working, router goes up to 85% CPU usage and the wireless client download speed is lower than before, not even reaching 700Mbps... I have several entries listed in /sys/kernel/debug/ppe0/entries but /sys/kernel/debug/ppe0/bind is empty. What a disappointment 
Good news, I've found the cause, this commit: wifi: mt76: mt7915 add tc offloading support. After reverting the changes, wed is back: 30% CPU usage at over 800Mbps. Here is the reverting patch if needed:

@nbd Dear Felix, please look at your commit mentioned here, because it breaks wed acceleration on RT3200/E8450. Thanks!
I would create a separate issue at github in the mt76 repo, which then can be closed once it is resolved.
I am not sure if this is a mt76 specific issue. If I remember correctly, mt7915, in addition to the Ethernet-WLAN offload, can also do those offloads from WLAN to Ethernet and WLAN to WLAN, but not in tandem with mt7622. So it may be a specific 7622+7915 issue; maybe it should be treated at OpenWRT code level?
for you to decide. You seem to know more than me there.
Hello, i have a problem.
I've finally recently flashed OpenWRT and everything went fine, but my download connection literally went down alot... and i can't figure out why.
With stock firmware i had a normal 940+Mbps, but now with OpenWRT i have around 160Mbps...
I tried with software offloading and hardware offloading on but nothing changes...
It's a PPPoE with VLAN ID 835 configured by adding a custom .835 after the wan name (every document i found speaks about a "switch" menu that doesn't actually exist in the latest version)
"Apparently" i've fixed it.
I've removed the WAN6 interface (i've found a post on github that is deprecated or something like that and interfere) so now only WAN (pppoe-wan) and a disabled WAN_6 virtual exist and reactivated Software + Hardware flow offloading and seems i'm back at around 930Mbps
After 6 days of continuously using the build with the new mt76 code (patched for wed), the router finally stopped the wifi interface with the same timeout issue (#690). But following the mentioned thread I saw many people actively testing and debugging the issue so I hope we'll have a fix soon 
LE: I will try using the firmware mt7915_wa.bin version 20230315163130 from rany2's mt76 repository.

Happy to open an issue on GitHub if it's worthwhile and move the discussion there if the expert's think it should be logged.
Hi,
TLDR: What is the reason for part 1, what to do to get stable 22.0.3.5 to run with 802.11s like snapshot image does (part 2)
Part1: I recently wanted to update one of my Belkin RT3200 from running snapshot 22040 to current snapshot to get Wireguard. My setup consists of 3 of these routers in a 802.11s mesh configuration (AX at 5Ghz, 80Mhz channel width) running flawlessly for months. After successful upgrade I could not connect to router over Wifi-connection, but connected with a local ethernet port, connect was possible. I further examined with tcpdump, that only broadcast and multicast traffic passes the bridged lan ports. I disabled the firewall, I set firewall rules to any-any-any-allow, but nothing changed that behaviour. Because of the nature of snapshots (and my humble knowledge of it) I did not have a fallback image to come to the state where I started (snapshot-22040). To get out of this I thougt I could try stable 22.0.3.5. Flashing the sysupgrade-Image (with or without keeping the settings) ends up in 802.11-meshconnection not coming up with the stable image. I tryed to find, why, and as far as I'm not wrong, the difference between snapshot and stable in terms of mesh is the packaging of openssl-libs in snapshot versus wolfssl-libs in stable.
Part2: So to make it happen, I tryed to create a stable image with openssl-lib instead of wolfssl using the openwrt firmware selector page (just replaced the 2 wolf-ssl packages in standard choice to openssl) and tryed to flash this paket. This gives unresponcable device at all (just ethernet connection, no wifi and therefor also no mesh network), so had to go to recovery and restart with the procedure.
I did not describe all my other non-successful attempts, think, that post is long enough, but, if someone wants additional information, I'm willing and able to deliver 
I guess you could compile r22040 to get it up again.
Here's the git hash:
❯ scripts/getver.sh r22040
eeba2a67caa2b9b92ffb9d756089408643971a2e
Running same r22040 with wireguard:
openwrt_SNAPSHOT_r22040-eeba2a67ca-cc9bb1bcdfb0-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade-22212.itb
Thanks for this. For my understanding: The scripts sets the git-checkout to the appropriate branch and I then have to compile the itb-file by myself? Or is this shellscript useable with auc?
Thanks to you too. I gave it a try (even not considering it to be used in "production"). It gives me the same error as the stable image does (mesh wifi does not start) so here is what (in both cases) the log says:
