GT-AX11000 keeps crashing after every few days (WiFi so it seems), and need to hard-reboot to get it working again

WPA3 was already disabled, it's set on WPA/WPA2-Personal for all the WiFi frequencies.
Also turned some stuff off like WiFi6 and such, and beaming, which is what I read is only for old devices.
See if these settings does anything.

40 mHz causes overlap on 2.4gHz. I’d change it to 20mHz. I’d also not use channel 5. Use 1,6, or 11. Change your authentication method to WPA2 Personal only.

Roaming assist: Disable
Bluetooth coexistence: Enable
DTIM Interval: 3
Beacon Interval: 100
TX Bursting: Disable
And one last thing….
Limit modulation to standard 256-QAM (MCS 9)
The way it is now offers zero benefit to IoT stuff possibly causing some instability.


Try this stuff. Hopefully it’ll help.

Boring stable WiFi on your GT-AX11000 for IoT:

Band: 2.4 GHz
SSID: “Dedicated IoT SSID”
Channel: 1 or 6 or 11
Bandwidth: 20 MHz
Security: WPA2-Personal (AES)
PMF: Disabled
Roaming Assistant: Disabled
Beacon Interval: 100
DTIM: 3
Bluetooth Coexistence: Enabled
TX Bursting: Disabled

Thanks.
It crashed again after a week (without your settings).
I'll apply your changes, but it's quiet annoying.
I'm tempted to put a nightly "restart" of the router, cause it's quiet frustrating, when my remote connection stops working when it was running fine :/

exactly what ive done with mine - I have split the bands though. I live in a small flat so distance isn't an issue really. so 5ghz 1 - fixed media devices (such as streaming box) 5ghz 2 - for laptops and phones, 2.4ghz is my IOT network.

mines been rock solid since the day I bought it and on that day put Merlin on it.

I think the hardware must be faulty to keep doing that. - if it does it with a clean setup and you have reflashed firmware cleanly, then it can only be hardware.

I use mine in AP mode now admittedly but when in router mode it was fine.

Let me know if this should be sufficient.
If it still keeps crashing, I'll enable the automated restart of the modem again:

You have turned your AX-class router into AC-class router. Intentional?

I had to search what you meant, but yeah, I put it to Wifi 5 instead of Wifi 6 to see if it would make the chipset stabler ?
I enabled that again, let's see if it still stays stable.

I think the issue is solved.
So far no crashes anymore, thanks for the help everybody !

i suggest to study in deep what DFS and TDWR is if you don't know this already.
in summary, by law (that every wifi firmware must respect), your wifi 5ghz is turned off for at least 10 minutes sometimes, where sometimes depends were you live.

once you have understood what DFS and TDWR is, this image will help you to configure a proper channel for your 5ghz wifi according where you live in the world.

i struggled 1 year and a half trying to understand why my asus gt-ax6000 drops 5.ghz connections and sometime get stucked too.
give DFS and TDWR understanding a try....trust me you will not regret

Hi,
Thanks for the link.
I'm in the Netherlands, and I've checked which channels to avoid.
So I set it to channels that do not affect these scanners, good point btw.

I had the same router, same issue as you. I created a script for the router to automatically reboot.

Tutorial - Automatically Reboot Asus Router on Network Failures

I wrote a script to automatically detect internet outages and reboot the router if needed, ensuring minimal downtime. It monitors internet connectivity by pinging multiple well-known IP addresses (Google DNS, Cloudflare, and Quad9) up to three times each. If any of the pings succeed, the script...

I ended up getting a new BE98Pro and retired the AX11000... I think it's a common issue.
