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.

I have already performed a hard reset of the modem numerous times.  The CPU spikes comes back within 30 seconds of creating a network and random reboots occur within 30 minutes.  I have tried multiple configurations after hard resets with the same results.

I have already submitted feedback via Asus Router multiple times.  I have not received a response from Asus.  I gave up and plugged back in my previous router as everyone in the house complains about the RT-BE92u stability.  Can you send me beta firmware to try?

I want to thank Asus support for reaching out to me and sending me the link to beta firmware version 9.0.0.6.102_37803.  After install and hard reset, there have been no more CPU spikes or random reboots over the last 24 hours.  I purchased Qualcomm QCNCM865 Wifi 7 modules for our laptops and everything is working perfectly with the Asus RT-BE92u router.

That is fantastic that your updated firmware is resolving your issues.  I hope the next public firmware release will help the rest of us as well.  🙂

UPDATE

I ended up taking my Asus RT-BE92U back to Best Buy to see what my options were.  The sales person in the routers area suggested I return the router and pay the difference for a RT-BE88U.  It would cost me about $140 more.  I could not see paying the extra money for a more stable duel band solution, so I brought home a new RT-BE92U. 

I tried to be careful and not use any options that I did not need.  I got the router up and running, loaded the newest firmware, and hard reset it twice.  I created my main network and all of my IoT devices piled on.  I was happy to see all of my CPU cores were remaining low and I had over 250MB of RAM available.  I let that run for a couple days monitoring it with the phone app.  My system log was receiving MLO errors every 5 seconds or so.  I thought things looked stable enough that I wanted to add another network to migrate my 2.4G IoT devices to.  I created the other network and moved a couple devices over and went to bed.  When I got up the spiking core issue was back.  My constant system log errors now were the thermal ones.  I was so upset that not only can I not run the router's advanced options, but I also cannot run multiple networks.  I was too burned out to do a hard reset and start over, so I simply disabled the second network and rebooted the router.  It came back up without the core spiking and has been that way for 3 days.

I have to ask, if so many people are having these issues, why hasn't an updated firmware been released since Christmas?  It has been over 6 weeks now.  I am happy though that some people are receiving the support they need to help them get up and running.

Just a follow up.  After 24 hours of updating  to beta firmware version 9.0.0.6.102_37803 with no issues, I turned on MLO.  Ram usage went from 61% to 67%.  The router has been stable with MLO on for the last 24 hours.  I'm going to purchase another RT-BE92u for wireless mesh mode for the other side of the house.
