RT-BE92U rebooting

[eagctx]

I see some other threads on the BE92U rebooting. But I think the situation I'm in is different.

I have it configure in AP Mode, so not as a router. It's on my local LAN and sits behind a hardware firewall. I had four(4) cables plugged into the LAN ports, the feed to a large switch with Internet access, two wired IoT devices and a desktop PC. I had trouble with it a week ago when it arrived and I just plugged it into a switch and disabled the 5 an 6Ghz radios and setup only WPA2. It seemed to run ok that way for several days.

Yesterday I swapped it in for the RT-AX86U that was my main Access Point. It immediately began rebooting itself in anywhere from 20 to 30 minutes. Today I bought a small five(5) port switch and moved everything onto that switch and plugged the RT-BE92U into also. So there's nothing plugged into it now but the single cable giving it access to my LAN and the Internet.

I was thinking that having all the other things plugged into it was perhaps contributing to the rebooting. But, no joy on that. It is continuing to reboot at the same 20-30 min interval.

I've now turned off the 5 & 6 Ghz radios, disabled WiFi 7, but left WPA2/3 on. Nothing seems to be helping.

I did get the new firmware, 3.0.0.6.102_37526 installed yesterday. I did a Hard Factory reset after installing it too. That's why I deployed it yesterday, I was hoping it would resolve the issues I had last week.

Doubt anyone has an answer, and I have called support to open a ticket; no work done on it yet though. Just letting the community know.

Does this mean you didn't have it connected via WAN on the Internet side? Basically using it as a switch with wifi?

Yes, essentially you're correct. It has an IP on my LAN and is simply supplying WiFi in my house. I have the Ethernet cabled plugged into LAN port 1 on the BE92U; nothing is plugged into the WAN port.

And, to be clear, I was using it as a switch, but not anymore.

Update:

Got up this morning and tried several things.

1. Manually, meaning from the downloaded file, upgraded/re-flashed the firmware. Immediately after that I did a factory reset from the WebUI. This didn't change anything and rebooting continued.

2. Did a factory reset using the reset button on the back. Again, no change. At this point I also moved the Ethernet cable from LAN port 1 to LAN port 3. Again, no change, reboots continued.

3. Did a Hard Factory reset using the WPS button. Moved cable from LAN port 3 to LAN port 4. After this I also disabled WiFi 7 and the 6Ghz on my Network.

Now the router has been running, without a reboot for 2h35m.

During this time I called Asus and opened a ticket. The tech said let's wait before they collect logs to see if what I've done has "fixed" it.

Since essentially three things were done simultaneously, a) move cable to different port, b) disable 6Ghz and c) disable WiFi 7, I don't know which has made a difference. Right now I've just re-enabled the 6Ghz and will wait to see if that causes any issues. If it doesn't, I'll re-enable WiFi 7.

I suppose it's possible that LAN ports 1 and 3 may be the cause, unlikely though. The only port I haven't tried yet is 2. Maybe I'll move my cable to that just to see if it works.

I'll post back tomorrow unless it starts rebooting again.

It MAY be the 6Ghz radio.

As I wrote in my last post, I re-enabled the 6Ghz radio and added it to my Network. It ran for 17 minutes more, and rebooted.

I was out for a while and got back and the router was non-functional. Power light

was the only LED on. Couldn't ping it. Had to Power it off to get back to it.

After that it ran twice more for less than 5 minutes each time before rebooting.

I've disabled both the 5 and 6 Ghz radios. I did this last week when I received it and it was rebooting.

At this point I believe it is defective. I have to get Asus to replace it.

This device has had 5 firmware versions published since December 23, 2024. While that may seem great, it suggests there are a lot of problems being ironed out in a short time span, with perhaps more to come. If they replace it and it still craps out, put it on a shelf for a couple months until the firmware stabilizes. You have a nice mature AX86U at your disposal.
