RT-BE92U is Unusable

[cbj1903]

I bought this router to replace the Eero router my ISP gave me with their fiber gigabyte service.  I updated to the newest firmware 3.0.0.6.102_37435.  Once updated, I performed a hard reset of the router.  The router has contant CPU core spikes approximately every five to six seconds.

The real problem is the router contantly reboots throughout the day.  I worked from home today and the router rebooted 5 times in 4 hours.  No real pattern to the rebooting, with the router being online anywhere between 26 to 98 minutes between reboots.  At lunch I gave up and replaced the  RT-BE92U with the Eero as I need a stable router to work.

Is this a hardware issue or a firmware issue?  There are many complaints online about this router.  Has Asus found a root cause to the CPU spikes and the contant rebooting?  Is there a fix in place? I still have a few days left in my return window to Best Buy.

On another thread dealing with bogus thermal errors in the logs Asus had been involved gathering information but so far nothing new.  Some have been given access to beta firmware and I'm not certain of their results.  The only way to gain access to it is through Asus tech support.  As for the router, I have not had reboots.  I have no clue as to why.  I have MLO, WiFi 7 on one network, AI Protection, Adaptive QOS, and Traffic Analyzer all active with about 80% RAM usage.  My CPU cores all do a dance from near 0% to 90% but honestly in a way that I would expect given the demands placed on them.  Plus, there are hundreds of bogus log entries about thermal errors.,  Asus is aware of all this including reboots.  

The concern I have is what's the source.  If it's firmware, ok, I can wait that out as I'm so far stable.  If, on the other hand, it's hardware related that's going to be another issue as I live in Costa Rica.  Personally, for all this router can do I don't think 1GB of ram is sufficient.  And based on the questions Asus support was asking in the other thread I don't think they really have a handle on the problem.  

I wouldn't tell you what to do, but it sounds like you have a pretty paperweight on your hands.  And by the way, I also got my router from Best Buy.

I also purchased my RT-BE92U from Best Buy with only a few days left in my return window.  Way too much of my time has gone into trying to stabilize this model.  It started out with the single core spiking issue with my system log getting nonstop error messages.  Then my wife that works from home told me her work VPN (not controlled by the Asus) has been having intermittent disconnects she never had with my older Asus router.  My daughter (not living at home) says her connections to my wired PLEX server periodically drops/freezes which it never did before.   I have rock solid fiber Internet so that is not a contributing factor.  While trying to troubleshoot the WiFi issues I decided to go around my house mapping out possible WiFi camera placement.  I was surprised how often I would be getting a good connection and the application would say "no internet".  So our radios would connect, but the router was not routing Internet traffic. 

I followed the advice given to make sure the latest firmware was loaded and do a hard reset.  This solved the single core spiking issue for a couple days, but it came back.  The error messages in the router also changed, but they are still repeating.  This router is so much more powerful than the model it was replacing (RT-AC68U), that I keep trying to make it work.  I got it at Best Buy with a price match for $219 plus tax.

I wanted a decent priced WiFi 7 router with all the bells and whistles to replace my old one.  This model is just too buggy.  Big question is, is it a software issue, or hardware issue.  If I knew it was software, I could possible wait it out for a golden firmware update to solve the issues.  Should I just exchange it for another one hoping I get a good one, or are they all running flawed firmware where many people just haven't selected the options that trigger the problems to start?

I bet there are many out there contemplating the same thing.

Keep it hoping for firmware fix • Return it for a replacement unit • Return it for a different model • Return it and get your money back and wait until the WiFi 7 market matures.

I have many ASUS routers in use and memory utilization is very high when you connect a USB HDD or flash drive, but I have not seen CPU spikes on the graph, ever.  I have read of CPU pegging 100% and I believe that was due to a hardware fault.

This is a nice model because if has all three frequencies, and the price is decent as well.  I would recommend contacting ASUS support.  And just to verify how many years warranty are you getting, because ASUS increased to 3 years on newer sold models at least here in the USA?
