RT-BE92U - On-going random losses of Internet/WAN access

[AndrewMcN]

I've had the RT-BE92U for a few weeks now and a couple of times a day it simply stops routing DNS WAN traffic and the Wi-Fi networks also stop routing. All Internet access grinds to a halt because of this. Sometimes it returns to normal on its own but today it was so inconvenient that I got it to reboot via the web UI. It's then fine again for several hours.

It's like the unit itself enters some kind of semi-hung/crashed state. I'm thinking there's some kind of memory leak or that the RAM capacity is insufficient. It runs for several hours and then begins going faulty.

I am 26 years into an advanced IT solutions architecture/engineering career covering pretty much all kinds of infrastructure. So, the most I'm guilty of is not trying the basics.

I am able to ping externally, however I tend to find that I cannot get DNS traffic to pass and that includes direct queries of external DNS services, e.g. 8.8.8.8 (I can ping this guy).

The Wi-Fi networks can't even reach the router itself. I have to go to my wired laptop to engage with the router. The router web UI responds normally. The system log just seems to show either long pauses between log entries or errors about wireless client disconnects.

This kind of error seems to be common in the log just now:

kernel: WLC_SCB_DEAUTHENTICATE_FOR_REASON err -30
kernel: WLC_SCB_DEAUTHORIZE error (-30)

Could be red herrings but they always seem to be around when the crashes happen.

I have a lot of smart devices. It says I have a total of 54 clients but the vast majority of those will generate very little traffic.

I use Sky Stream. So, there can be a lot of throughput there. I also watch a lot of Twitch. Again a lot of data passing through for that. Nothing I wouldn't expect this router to handle though.

I have AiMesh up and running with two nodes.

I use the Time Machine backup capability with a USB drive attached. There's an hourly backup.

I have the AiProtection turned on. DoS protection enabled.

I also have the DNS over TLS enabled opportunistically but I've tried putting this off and it doesn't help.

I just fear that the hardware spec isn't able to handle the workload.

It just seems like the firmware isn't stable enough yet. I need to decide if I should be returning this or just be patient and wake for the next firmware updates.

Anyone else with this router experiencing issues despite factory resetting?

I think that the MLO is not turned on by default, but the essence of wifi 7 is MLO.

Is your smart connect on? Mine is and still having intermittent WiFi or wan disconnect. Even reboot sometimes

Yes, Suddenly I'm having the same issue.  I haven't resolved the problem yet but I have been able to create a work around for me.  I disabled the 2.4 Ghz and the 5 Ghz antennas on main router.  Leaving my AImesh antennas on and the errors are gone and most of my devices are connecting through the AImesh.  I still have some routing issue with Roku will not connect though it sees the network.  I'll work on it some more over the weekend but if you have any new information to share feel free.

I'm still getting random disconnects on 37526. All bands are on though - Asus should fix this, I purposely picked this router for Wifi 7 6Ghz...

[EdK17]

Same. So far only setting the wireless to eco mode and once a week reboot works for me
