Sorry, I had moved the device (unplugged it) before seeing your reply and I see nothing under /sys/fs/pstore. But I now know better for next time.
hello @daniel
my colleague has the same router as me but he lost the openwrt wifi on his router, he uses sqm for the video game and suddenly found himself in moderate nat,
instead of nat open, but with the difference that this time the router did not go back to the original blue interface as in the past, it disconnected 10SEC and reconnected, and the wifi came back, this problem could it be recurrent thank you?
ps I don't have the version of its software
The best would be if you manage to extract the logs from /sys/fs/pstore next time it happens, so we will be able to reproduce the cause (I didn't manage to crash it even once, but that can well be related to the behavior of wifi clients; on MT7620 there were problems which could only be triggered by WiFi action frames emitted by an Xbox.... you get the idea...).
If you that is not an option for you and you just want crashes to silently reboot the router and keep things functional, you can also disable the PSTORE feature in the U-Boot environment (see above).
Ah well seen Daniel he is on PS5, not Xbox I told him to unplug in case, like you for the moment mine has no problem 
Where is the best place for uploading pstore files? I have a couple. The device boots into recovery frequently. Finally read this thread about pstore files and how to clear them. Good stuff.
I have two Belkin RT3200 can't get mesh working. I just played around using the tutorial that I used in the past without success. Could someone post a working config to help me, please. The openwrt tutorial has worked in the past with other devices but does not work with the Belkin RT3200. I used the network/wireless setup and the command line examples. Using latest snapshot with wpad-mesh-wolfssl.
iw dev mesh0 station dump
iw dev mesh0 mpath dump
With the above two command there is no output. Log file looks like the mesh0 interface is created. Not sure if it is a belkin problem or something that I am doing wrong. Probably the later.
The tutorial that I have followed is https://openwrt.org/docs/guide-user/network/wifi/mesh/80211s
I have looked at other tutorials also but no positive results.
good evening everyone does upnp work on rt3200 it does not seem to want to make it work because i have xbox and ps5 several machines, thanks in advance

Thanks for the links @elan and @smileys29 and I actually followed all the tutorials you listed before my previous post, the last article posted is excellent. I guess I should have listed all the links I reviewed. I think there is a bigger problem. I been using trying belkin rt3200 to another belkin rt3200 and mesh setup won't work even a simple setup. Decided to try Belkin rt3200 to Netgear r7800 and mesh network came up on the first try. Exact same setup. Will try Batman mesh with the Belkin to Netgear r7800 to see if that works. I have to try to figure this out. I am stumped after several days. Will try to turn on some debugging output to get more information.
Noted kernel crash when bringing the network/wifi up and down.
Pstore shows this.

Thanks for replying.
Update. Finally got a ping going with mesh and this is what happened on both belkin rt3200 after pinging the netgear. All three routers crashed.

I think I found the reason for going into recovery. Will try something different in the morning.
Hope this helps.

I can confirm that 802.11s mesh was working on a couple e8450s in AP mode when I tried it a week or so ago.
Set all radios to the same frequency.
Add an 802.11s interface to the radio, tied to LAN.
Set security to WPA3-SAE and set the same key.
Done.

Thanks glad to here will give it another try. Did you use batman or 802.11s? Did you use wpad-mesh-wolfssl?
Thanks I will try harder. Glad to know it works.

This looks like a rather generic problem somewhere in between batman-adv and mac80211.
Maybe @nbd, @ryderlee1110 or @lorenzob can make more sense of the crashdump?
Did you set option mesh_fwding=0 for the 802.11s interface in /etc/config/wireless? Things are known to explode if both 802.11s forwarding and batman-adv are enabled...
Please share your /etc/config/network and /etc/config/wireless (remove identifying information and credentials before pasting!) as well as exact versions of kernel modules and hostapd/wpa_supplicant/wpad.

Looks pretty similar as the dump above from @BeauSlim :
Based on those addresses with lots of zeroes, the first guess is that somewhere the value x is used as a pointer instead of the location of the item x, or a certain attribute of item x.
I didn't use anything other than the base image, and the steps I listed. Crazy simple, right? It is my understanding that LUCI shows the mesh as "unencrypted" but that LUCI is incorrect. I may be wrong about that. I think you still need to use BATMAN if you want to use VLANs over the mesh.
I may revisit meshing but having both a mesh link and an AP on the 5GHz meant that the AP was rather slow. My main concern is speed to my AX laptop, so I am currently running my 2 e8450s as wired APs.
Just a off topic question. What are the road blocks to achieve a release candidate for this router. The snapshots are stable enough to use as a production instance.
The problem is that most targets are still on Linux kernel version 5.4 and we are currently already quite busy with the ongoing 21.02 release (rc4 is out these days). Once 21.02 works well, more resources will be available to port remaining targets to Linux kernel version 5.10 and then make a release based on that which will include support for the E8450.

Thanks for the info. Makes total sense.

Started with a fresh snapshot about 4-6 days old now. Decided not to use batman but keep it simple and use 802.11s only.
No encryption mesh worked nicely with 2.4Ghz and 5Ghz frequencies.
No success with wpa3 encryption and 2.4Ghz. The 5Ghz radio worked perfectly with wpa3 encryption, but on first connection had kernel oops and is identical on both belkins. However, mesh works nicely after initial kernel oops. The 5Ghz radio the mesh network only works with channel 36, no other channel will work with mesh network on the 5Ghz radio. All error logs are posted below.

Error from with wpa3 encryption and 2.4Ghz radio and no connection. Searched on internet for this error was not very helpful for me. Way over my head. Below is a link. The link did discuss that some people had mesh working only with 5Ghz radio.

You report is quite complete and describes the symptom very well. Please file a bug report with everything you also wrote in this post on https://github.com/openwrt/mt76/issues
Make sure to also mention the fact that this is MT7622BV + MT7915E (it's obvious in this thread, but may not be obvious for mt76 devs when posting there)
