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?

The current firmware is buggy and we should wait for update.

Hi @AndrewMcN ,

To assist you more accurately with this issue, we would like you to confirm the following:

1. Firmware update: Have you updated your router's firmware to the latest version?
2. Factory reset: We recommend that you restore your router to its factory settings. For detailed instructions, please refer to the following link: [Wireless Router] When Standard Reset Isn’t Working: Hard Factory Reset - Models list | Official Sup...

If the problem persists, please use the system reporting function immediately when the problem occurs and provide relevant information so that we can conduct a more in-depth investigation.

You can submit a feedback form Web GUI (http://www.asusrouter.com).
1. Connect your device to your router and log in to Web GUI(http://www.asusrouter.com)
2. Find “Administration,” and tap “Feedback”
3. Fill in your region, email (required field), ASUS Service No./Case No.(not required),Select the feedback problem and description.You can also write down comments/suggestions. More details might help us to analyze the issue you have encountered in a faster and more efficient way.
4. Read the agreement and click “I agree.”
5. Tap “Send” to submit your feedback.
Then provide the product serial number, the time of submitting the issue report, the email used for filling out the issue report, and the time when the issue occurred as well as the device MAC address via private message.

Thank you.

I updated to the latest non-beta firmware 2 weeks ago. This led to an incredibly unstable router and I then proceeded to a standard factory reset. The router was then a lot more stable.

I will use the feedback form if the issue occurs again today.

A potentially related behaviour problem seems to be latency or unexpected delay on certain devices, primarily Wi-Fi, when attempting to access WAN/Internet services after a period of idle time. It's almost as though the connection has been put on ECO mode or sleep. My devices do not load requested resources as quickly as I'd expect them to or as they do after the device has "woken up" its connection. Whatever this is, it's an awful experience. The delay is around 30-60 seconds before web pages load. They then load quickly as though the connection has come up to full speed. I didn't have this with my previous GT-AXE16000 or the RT-AX82U before that. I am hoping this is another firmware issue and not an indication that the hardware cannot perform well enough. I don't recall seeing any configuration around sleeping connections when idle.

Mine beta version is 9.0.0.6.102_37421-gd076862_1052-g64241_BB0B and is quite stable since update (about 4 days usage). IPSec VPN server, Wifi7 signal, Wifi channel dropped and Smart Connect issues were fixed but other bugs still need time to prove.
