Looking for Feedback: RT-BE92U stability issues

[RMerlin]

Hi,

I'm trying to gather more info/feedback from RT-BE92U owners who are suffering from major performance issues, or general instability or crashes.

If you are experiencing issues, please test again using the latest stock firmware (if you were using Asuswrt-Merlin). If you can still reproduce the issues, then please report them back here so I can forward the feedback to Asus, as at this point there doesn't seem to be any internal info hinting at widespread issues, which is somewhat surprising. Using the Feedback form on the webui is also a good idea, as it will forward technical details to Asus for further investigation.

I do not mean to derail the thread, but is it remotely possible that GT-BE98 Pro also have general instability issues?

Seems to be more okay on my rt-be92u and uses 6ghz, I don't know how 2.4 or 5ghz are like that as I have disabled them so I don't know about these,
Because it was very disconnected from the beginning but I haven't noticed much now anymore,
I'm going to update my dad's rt-be92u router with beta 2 because it works pretty okay for me on my Rt-be92u

So far the most serious issues seem to be related to the Ethernet ports.

Going to change from yours to ASUS stock now....

@jzchen, test the reported LAN ports isolation when WLAN radio clients isolation is selected. If this one is reproduceable - it's a huge bug. I know it was reported to ASUS already, but see what is happening on latest Asuswrt. Also mention your hardware revision, some folks report V5.1 already. This is unusual, I don't remember seeing so many different revisions in short period of time. Thank you!

I've experienced repeatable 2 issues while on the current FW, both relating to the 2.4 radio.

I have some smart bulbs, that if you switch them off at the power, so that they suddenly lose connection, the 2.4GHz radio will crash and restart.
As I have said in posts elsewhere, I'm now avoiding the issue by blocking them from connecting to the network. Essentially they're now dumb bulbs, but we weren't using them smartly in the first place, so no loss. Probably an issue with the driver and out of ASUS's control, but an issue none the less.

The other issue that I had, was when I reduced the Tx power of the 2.4GHz. The radio was generally unstable, would restart often, ran core 2 at nearly 100% and consumed much of the free memory. Returning the radio to full power fixed all of the mentioned issues. Easy work around would be to disable or remove the setting until they get it working.

I don't know if either issue occurs on the other 2 radios, as I haven't tried.


The DNS server crashed on me 2 or 3 times, but I don't know the cause and can't repeat it. After returning the Tx power to full, a lot of my issues have gone away, this might might be the same.

Over the past 6 weeks, I have been running 3 SSIDs: one for 6 and 7 clients, one for 4 and 5 clients and one for IoT devices. This seems to have made the unit and clients a little happier with a small reduction in re/de authorisations, connects/disconnects and swapping between radios. To me this suggests that there could be some more work to be done with its tolerance to older devices and protocols. I suspect that will come in the next fw, if the February fw for some other ASUS BE routers is anything to go by.

RT-BE92U - I did a factory reset about 13 hours ago. Its a simple setup with a couple of vlans for 14 IoT devices, expressVPN and and a few scripts, i,m not aware of any problems so far

Hmmm. This is going to take some effort on my part... (No sarcasm intended)...

I reported somewhere here my prior V3.0 bricked on stock firmware. I did not purchase it from an ASUS authorized vendor but there's a story behind that too. Current one is V4.1 which I got from MicroCenter/ASUS vendor...

What's up with ASUS routers, Ethernet ports, and ASUSwrt 5.0? I remember when the GT-AXE16000 got switched from 4.0 to 5.0 the whole router's Ethernet would go out, during the night hours....

EDIT- The bricking happened while I was out with my mother having our (almost) daily lunch, basically no effort on my part. A couple of new firmware populated quickly after the return...

Not sure if this is this specific bug, but they confirmed having already fixed a bug related to ports 2-4. The fix will be included in the next stock release/GPL merge.

I’m using an ASUS RT-BE92U AiMesh (2 nodes, wired backhaul) and have been chasing intermittent stability issues. I’m currently on the latest official ASUSWRT firmware (3.0.0.6.102_38980).

My environment / current setup

• Total Wi-Fi clients: ~53 (roughly 2.4 GHz: 30, 5 GHz: 16, 6 GHz: 7)
• Additional ~50 Zigbee devices (handled by hubs, not on Wi-Fi)
• Three separate SSIDs by band:
  • 2.4 GHz IoT SSID (WPA2-Personal only)
  • 5 GHz SSID (general devices)
  • 6 GHz SSID (high-band devices)
• MLO disabled (I previously tried mixed/combined setups; now fully separated by band)

Issues I experienced (before)​

1. Random WAN drops / internet loss
   • WAN link looked “up”, but internet connectivity would disappear unexpectedly.
   • I tried various tweaks, but the most impactful change was setting custom DNS (instead of defaults). Since then, WAN drops have been much less frequent / seemingly gone (so far).
2. 2.4 GHz instability (felt like partial Wi-Fi restarts / reconnection storms)
   • 2.4 GHz clients would intermittently disconnect/reconnect, and it sometimes looked like only the 2.4 radio was restarting.
   • I tried many typical stability settings (separate SSIDs, WPA2 only, no MLO, etc.) with no clear improvement.

What seems to have helped (surprisingly)​

I changed 2.4 GHz channel width from “20 MHz only” to “20/40 MHz (Auto)” — and the network feels significantly more stable afterward. I’ve only observed this for ~12 hours, so it’s too early to claim victory, but the improvement is noticeable.

I think there's a LAN/Ethernet concern...

I've always liked SmartConnect, specifically 2.4 and 5 GHz. It's been around and brand agnostic, (other brands have it too aka band steering). It allows bandwidth intensive clients which typically also have 5 GHz capability unload the 2.4 GHz and move to the 5 GHz....

That said my oldest device is WiFi 5/AC, so 3 generations of Wifi in my household, but I do not have anything older....

Confirming I don't suffer any performance problems with my GT-BE98 Pro. It's rock solid.

Long time Merlin user, thank you for many years of improvements. I just moved and decided to upgrade my RT-AX86U Pro Wifi6 router to the RT-BE92U Wifi7 router. I am still on the latest stock 3.0.0.6.102.38980 firmware Been following this issue. I have no devices plugged into the router on the switch, (well I do have a RPi as a pihole but it's not working anymore since i swapped routers and I'm kinda tired of trying to make it work again so its turned off). I am having near daily issues with the Wifi LAN resetting/dropping out and then reconnecting. The router isn't rebooting according to the uptime stats, it's just the wireless radio that seems to be resetting. It usually occurs in the evening when there are multiple devices streaming, phones, TV's, desktop pc's, consoles, etc.... I had MLO enabled (on the Wireless page, MLO Tab) but have not turned on the MLO Fronthaul as I didn't really understand what it would do or not do just yet. Taking time learning the new router features. My Samsung S24 Ultra is getting amazing speed with the L4S feature turned on and Wifi7 enabled and the two gaming desktops have MSI Herald Wifi 7 Max PCi-e cards (with the NCM865 Wifi7 Module) are able to pull full 2Gbps bandwidth through our ISP on a Netgear CM3000 Modem. We have around 25 devices on the network at a given time, with 10 smart switches/dimmers/thermostats on the factory IoT 2.4Ghz network. The rest of the devices are generally but not always on the 5Ghz or 6Ghz bands if available but obviously some of them use multiple bands.

I came here to see what the latest state of the firmware was for this model. I have auto reboot enabled every 24 hours, 7 days a week hoping that would help, but it doesn't seem to matter. I just turned off the MLO feature to let that run a few days to see if that helps. What seems to be the case is when one or both of those desktops are connected with them playing games and streaming, along with all the other devices running...it just seems to get overloaded, though when it is happening I log into the router and don't see a cpu/memory load issue. I don't know how to read the system log or wireless log to understand if what's there is expected or not.

If I can provide useful info let me know. I submitted a report to Asus using the feedback tab. Also emailed the debug file to Asus.

Thanks, that`s all you can do at this time, unless you can manage to reliably cause the router to reboot, in which case sending logfiles after a crash would be helpful. Sending them logs following a radio crash might be helpful as well (particularly if ALL clients get disconnected, indicating it`s not just a single problematic client, but the router itself resetting its radio).

I need to see if I can reproduce the crash once again with the stock firmware. Been too busy with work today to do anything beside just turn it on with a mini PC plugged to a LAN port, and leave it running in hopes of crashes.

So far the most serious issues seem to be related to the Ethernet ports.

I have owned many ASUS routers over the years. The RT-BE92U, to me, is the old trusty AC-86U on steroids. I haven't had a single issue with it since I bought it.

Setup:

Router 1 - Main = Hardware revision 4.5
Router 2- Node = Hardware revision 1.0

MLO = Enabled
SmartConnect = Enabled
VPN setup using NordVPN, which is built into the UI; you just enter your code. I previously had it set up with AdGuard VPN and ExpressVPN using OpenVPN, and they also worked fine
AiMesh in Wired backhaul = very stable
AiProtection = Disabled
QoS = Disabled
UPnP = Enabled
WPS Setup = Disabled

All channel settings are left at their default values.

On the LAN ports topic, I have one port connected to the wall which is linked to the Mesh router on another floor. I also have my laptop connected to it and the IP Phone. No issues at all.

Firmware: 3.0.0.6.102_38980

This router is better than the RT-BE19000 I had a while back, which I returned due to having a very poor signal, even sitting right in front of it. I think it was a lemon.

The RT-BE92U is an excellent router at a very attractive price point for those who want to have a WiFi 7 router.

the old trusty AC-86U

Many folks around don’t have old RT-AC86U routers because many of them died young. It was one of the models with above average failure rate. I had like 10 broken units at one point, managed to revive 4 using the others as parts donors.

 

[jzchen]

RT-AC68U? Or RT-AC86U?

So far so good on stock firmware... (I'm afraid I have other things to investigate)...
