Hello everyone,
Since I started to use openWrt, I have an issue with wifi. If I enable the 5GHz band, the router crashes randomly. Almost all LED switch off, and it's not possible to access the router anymore.
I need to hard reset the router to start using again.
I'm now on openwrt 24.10 but had the same issue on openwrt 23.10. I checked on forum and sometimes people said its can be a driver issue with the wifi card but I cannot find a solution.
The router is an Asus RT-AX53U.
Should be 24.10.5 unless you know better.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
My exact actual version is 24.10.2
Here is what you asked. Wifi 5GHz is disabled.

Moreover to say that I was with a different ISP before (so a different configuration) and have the same wifi issue
Check mac addresses for conflicts
EA8500 had a mac confict between wan port and radio
Can you give me more information please ? What exctly do I need to check with MAC address ?
This one does not, but one can set MAC to random and never see those....
Edit 2.4 wifi access point - go to lower part - advanced, about end of 1st page ypu can select random MAC, repeat with 5GHz and try to enable it.
There is nothing "scary" in your config that should warrant a crash. As I see you emulate old router on WAN port?
You should sysupgrade to the newest 24.10 series release (or to the newest 25.12 release candidate). It makes no sense to try to debug a problem that is possibly already fixed in newer releases.
Not sure the problem will be solved in the new 24.10.5 as it was already here in 23.x and still here in 24.10.2
I had same device up to 24.10.3 and it never had any problems whatsoever..... Now back to OEM it serves a friend of mine....
Install owut and keep it upgraded, even though I dont think it is a problem at this point.
OK. I forgot to say I'm using LuCi.
luci
OK, it is luci-app-attendedsysupgrade then
Just tell us how it goes -> upgrade to 24.10.5 -> try to enable 5GHz (wait 10min for AP to appear)
OK, just done it. Then crashed 2min after (only LAN LED on, even Power LED is off)
You speak about "vendor id" ?
OK, connect a PC to the LAN port. ssh and in the console run logread -f and start 5GHz. This will show some logs before the crash
Yep, if you did it knowingly there is no problem....
Log from before activating 5GHz to now (not already crashed for now). Hope I don't share sensitive data as I don't really understand what's in log for now

All is in order, you can edit away last 3 pieces of client MAC addresses.
It shows one client roamed from 2.4 to 5GHz - I think you are all set now.
You can add
option background_radar '1'
to 5GHz radio section and use automatic channel selection - the device supports background radar detection and escapes radar instantly.
I upgraded to 24.10.5 as recommended
I don't understand what you mean
Already connected duccessfully in the past, and still had crashes
I don't have many Wifi networks in the area, do you think it's still usefull ?
