RT-BE92U Persistent Thermal Zone Faults

[RicoSuave]

First post here so bear with me if I miss anything. Since purchase, my RT-BE92U has been plagued with the same issues others have posted here. Up until the new firmware version dropped, I was having constant problems with network stability. I am currently running the latest firmware version (3.0.0.6.102_37435) and a lot of the issues seem to have been resolved except for one. Before the firmware update, I was seeing intermittent thermal zone errors in the system log. Since applying the update, I am consistently getting the following errors that appear every 3 seconds exactly:

Jan 4 18:29:52 kernel: read_bpcm_reg_direct_keyhole: Wait for completion failed, devAddr 0x3, offset 24, idx 2
Jan 4 18:29:52 kernel: thermal thermal_zone0: Failed to get RAIL 0 temperature, ret=256
Jan 4 18:29:52 kernel: thermal thermal_zone0: Failed to get temperature, ret=-1
Jan 4 18:29:52 kernel: thermal thermal_zone0: failed to read out thermal zone (-1)

On occasion, the errors coincide with a drastic decrease in wireless network performance. Under normal conditions, when connected to the 6GHz network, my wireless network download speed averages around 1100Mbps. This will drop to a nearly unusable 2-3Mbps. The 2.5GHz and 5GHz networks also see a decrease in speed to around the same 2-3Mbps. Wired clients seem unaffected. Once I perform a hard reset to the router, it seems to correct the speed issue for a while, but the thermal zone errors continue to persist. This seems to happen anywhere from once a week, to every day. Performing a hard reset isn't something I want to nor should have to keep doing to correct the issue every time it happens. Please let me know if there is anything else I can do to stop this from happening. I am getting very close to returning this router and exchanging it for a different brand. Thanks.

I tried 2 RT-BE92u units. Got tired of the errors (not an issue by itself...) and the fluctuating performance with real drops (a real productivity problem). I switched to a different router.  I'm getting much more stable connection, reliable speeds, and actually better range around my ~1700 sq ft condo. A dead spot with a Calix router was a weak spot with the BE92 and is now not an issue at all with the new one. 

For those interested, it's wifi 7 at a similar price point and from a manufacturer that people might avoid due to noise of a ban. Just sharing in case people eventually want an alternative.  I'm still rooting for Asus to make this router good. Just got tired of all this (and the investigation being a time sink). Asus's features and GUI are better, but I needed a simple, reliable answer.

I almost pulled the trigger on a router from the same manufacturer and probably the same router you're referring to.  I was a little concerned about rumors of a ban.

@DesiBuckeye They said 2 business days but that was Friday so I'd expect "maybe" Wednesday.  But I have received communications from two different Asus tech support yesterday (Sunday) following up.  So, we'll see.

Time frame? thank you

still having the issue and hoping for a fix. I have to return router to best buy soon or I'll be out of $$$. had to reboot again over night. staying tuned here. thnks
