RT-BE92U Nothing but problems

[Alcazar]

I got this 3 days ago to go with my ROG STRIX GS-BE18000, and 2 x AXE7800's on an AiMesh set up, and it's been nothing but problems on my network ever since.

I have been usuing Aimesh since 2019 and have used over a dozen AC, AX and now BE routers without a single problem.

This BE92U made sure that all changed very quickly.

Here's the setup I attempted to run it with:

1. The BE18000 is the Primary Router connected to my 1000/100 modem.
2. Wired connection to the BE92U upstairs
3. One AXE7800 5-metres wireles through a brick wall to the BE18000 - both downstairs
4. Second AXE7800 7m away through a brick wall wireless to the BE92U  - both upstairs

Issues:

1. The entire network chugs along slowly when the 92U is connected
2. Upload speeds to from 90-95 to 10-20 mbps when it's connected
3. Random device disconnections all over the house (around 25 devices, some wired, others wireless)
4. Cannot connect either AXE router via wireless to the 92U, they will only Aimesh connnect to the BE18000 even if it's not the best option for distance and interference

Solutions attempted:

1.  Reset to factory firmware over 20 times - no benefit
2. Restarted and reset all routers - no benefit
3. Set up new network from scratch - no benefit
4. repositioned AXE7800 2m away direct line of site to the 92U,  still won't connect to it
5. Updated 92U firmware released 31/10 - same behaviour
6. Removed AXE routers from network (maybe Wifi 6E with interfering with Wifi 7) - network still laggy
7. Turned off MLO - I always have it off as it would otherwise create issues on the AXEs - same behaviour

No matter what I tried, the same issues persist

1. Laggy network
2. Cannot Aimesh wireless to the 92U

Removing the 92U from the network and connecting ethernet to one of the AXE7800's in it's place allows the entire network to run smoothly with high speed and low latench across the entire house except 1 section, which is why I needed a 4th node there.

Seeing the amount of people who have had issues with the RT-BE92U and having my struggles with it, I have come to the conclusion that this router is a complete design failure from ASUS. 
I spoke to ASUS support and they admitted having a lot of problems with them worldwide.

It's a shame as I have been using ASUS routers with no problems for over a decade, Aimesh for around 6 years, but this one router destroyed that entire experience and loyalty. 

I am going to return it and not worry about it. After wasting 3 days on this, my trust of ASUS quality and reliability has definitely taken a huge hit. 

Has anyone been able to get it to work sucessfully in a mixed Wifi 7 + Wifi 6(E) Aimesh?

So I persisted with a few more ideas over the weekend but nothing worked, all were wireless backhaul based.

In the end I said, stuff it, why don't I just try run a new ethernet cable all the way from my office to the other end of the house.
After much pain getting cables through cavities and roof spaces which were like 45 d celcius, I got the cable through and terminated.

Connected it up, and voila, it's working fantastically well, so far at least. Getting virtually no latency on wireless and my speeds are consistently close to 1gb download. 

It looks like the BE92U just can't deal with wireless AiMesh, it needs wired backhaul.

ASUS may eventually fix this but at least you were able to incorporate a solution. I can't get around in my attic to install Ethernet cables. I have to wonder if ASUS actually wants everyone to switch to their more expensive offerings for full wireless operation. At least my GT-BE98 Pros and BE96U are working well now (fully wireless) - for a welcome change. Although, latency is still high.

Here's a note you may appreciate. ASUS can fully control their router updates at any time. They even turned on automatic updates by default in the last firmware update for my system - and added a note that they still could do updates and changes even if you turn the feature off in favor of doing your own manual updates. I had to change the time of day this takes place so it wouldn't interfere with my client connections while in use.
