Should should look at logs.
logread through ssh or status/system log through Luci.
your previous wireless configuration should include some settings not compatible with 22.03
Logs should point to the wrong parameter (without having to reconfigure everything from scratch)

Thanks I will retry and install 22.3.2 other day when I have time and wifi is not too demanded at home.
@ariznaf I have noticed that interface names are changed in snapshot vs 22.03.
If I recall 22.03 is like wlan0, wlan0-1, wlan0-2 ....etc
but snapshot is like wl0-ap0, wl0-ap1, wl0-ap2 etc.
As others mentioned you can recover your wifi config a couple ways but keep config to downgrade does not work because of the name changes on the WiFi interfaces. Maybe other things break too I'm not too sure. But for sure downgrades seems less reliable than upgrades.

Thanks a lot.
Yes, I have realized that the problem was with wireless names.
Today I have been dealing with the problem and trying to revert to 22.3.2
I think I could do it.
I began installing the openwrt-22.3.2 firmware keeping configuration and then adding all modules that seem to differ or were not installed, attended sysupgrade, luci-theme-openwrt-2020, wireguard, sqm, adblock ando others.
I am not sure that I have installed everything as it was, but I think it is working.
I had to delete and redo all wireless networks, but now they are working.
I have activated fast transition and it seems to be workgin now.
Fast transitions seem to have changed from 22.3 to snapshots, as in the snapshot is in a WLAN roaming tab while in 22.3 is under wireless security.
It took me quite a while to discover that.
@ariznaf - watch out for this if you're trying to do fast roaming on 22.03.
"I had a very similar issue and can't recall what the fix is on kernel 5.10 / OpenWrt 22.03. If I remember correctly it is no longer an issue in kernel 5.15 / OpenWrt master due to upstream DSA driver changes. If possible you may want to test a snapshot build and see if the behavior persists."
So your mileage may vary on using FT on 22.03 depending on what you are trying to do. There are several other issues linked to that issue as well related. I too have had issues with Soft/Hard flow offload and FT.... having to revert to no offload for FT to work.

Thank you, I am getting a bit mad about this.
But it seems it is not just a matter of the router model, as it does not work in my fritz!box 4040 access point either.
It seems that there are draw backs with wpad implementation. It seems to work in previous hostapd (but it does not support WPA3).
I will read it carefully any way to see if it helps.
Hi all, Thanks in advance for any advice/assistance! This thread is obviously full of great information.
I picked up two new E8450's and am setting them up. I used dangowrt's installer image and then flashed 22.03.3 sysupgrade via luci. Everything is working amazingly well.
One thing I am unsure of is do we still need to use the custom installer image first if converting to UBI? Or can I just use one of the images directly from OpenWRT? I see that there are kernel ubi images that are for installation and wasn't sure if those existed at the time the information on the wiki had been updated.

yes if you are installéd ubi Always ubi you will be installed in the future
we still need the installer image from dangowrt for the initial installation/conversion. Even with 22.03.3, the main OpenWrt buildbot does not produce the UBI installer image.
The dangowrt installer flashes a new bootloader, converts the flash partition system structure to UBI and flashes the recovery image (that you use later to flash the normal sysupgrade image). That is the core of the conversion.
But after that stage, there is no reason to use the actual UBI sysupgrade image from dangowrt download site, as you can just download and install any UBI sysupgrade image (like 22.03.3). Or you can compile your own.

hnyman, thank you for the detailed explanation. much appreciated!
You only need the sysupgrade UBI image from

I presume this occurred after a short loss in power and reboot.
This is after having installed the Release v0.6.4 installer.
2.4GHz WiFi seems not to be working but 5GHz WiFi seems to be working.
What's the problem/fix?

I just wanted to say a big Thank You to all involved developers and especially to @daniel. Danke!
I have been using this router with 22.03.2 without any issue for 2 months.

i has this problem 2 days ago
my router has recovery initframs
so he works perfectly while 4 month
i do'nt know why he happens but i think he take a security maybe a lot of device connected cause crash
Please connect to the device running in recovery mode via SSH and do this:
cat /sys/fs/pstore/*
rm /sys/fs/pstore/*
Share the result, so we get to know the cause of the crash. After deleting the pstore record the device should come up in normal production firmware again after reboot.
hello daniel i'm really sorry on the spot
but I deleted the dsmeg message 
all I can confirm is that the router was working fine it was flashed to 22.03.2,
and when I saw that my wifi no longer appeared it was in the blue recovery interface, after rebooting and erasing dsmeg it automatically returned to 22.03.2 and the classic white luci interface
this happened to me only once in 4 months and it was two days ago...
if i reproduce i will make the command at this time
cat /sys/fs/pstore/*
rm /sys/fs/pstore/*

Any thoughts on: Belkin RT3200/Linksys E8450 WiFi AX discussion - #3284 by Lynx?
After not the first reboot but the second I no longer see the errors on the affected device.
Latest snapshot has somehow broken 5G wireless here too.
@Lynx reports that 2.4 is not working......
5 seems fine.
2.4GHz WiFi seems not to be working but 5GHz WiFi seems to be working.

My main concern is about the mtdblock2 read errors. I thought that may be related to 2.4GHz issues I experienced. It occured right after power cycling by switching the little switch at the back off and then rapidly back on. The errors went away with two router reboots. So now I'm slightly perplexed. At least @hnyman reported the same error. Isn't sector 256 / block 32 outside the range used by OpenWrt? So what does that mean? That some data is not ECC compliant but not used? Shouldn't we fix that? Why does it only come up with one boot and then fixed by reboot? Is it that on power cycle one of the WiFi chips went into a bad state and that gives weird reads of out of range memory?
