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?

Got the RT-BE92U just before Xmas and have been really pleased with it - until now it keeps power cycling at random, every drops and it reboots. I am also seeing hundreds of logs with kernel: WLC_SCB_DEAUTHORIZE error (-30. I disconnected my USB HDD but have 4 nodes, 1 wired, 3 wireless.  Main change today was adding new node, my old previous main router RT-AC68U.  I fail to see how this can have caused such a failure but will turn it off to test.  I also notice the power adapter on the RT-BE92U seems loose.  You only have to breathe on it and I swear it reboots.  I can't swap out to the old 68U supply as they have different voltages.  I really hope this thing isn't an expensive mistake.

So now after 1 Week and done the final Configuration of the Router, it's running smooth without any Crashes or Issues.

I've sheduled a Daily Reboot in the Night (here in Germany your Connection got reconnected every 24 hours, so better to sheduled then random). The Protection Function is disabled but i don't got the Feeling Something is missing

Yes I've always set mine to reboot in the night, seems to help but I'm still struggling with the 92U.  I hard two hard drives on the 68U and the latest router can only handle one, and it's not letting me finding it in Windows explorer and the FTP function isn't working with the credentials I set.  I am deeply beginning to regret get this latest product!
