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've updated to 37500 and so far have 1d 8h up time without thermal errors. Never had stability issues with wifi while experiencing thermal logs, so maybe a difference with mine. I did not enable features which were off by default from the last hard reset. Did not hard reset after current update.  All 3 bands are On, plus an additional IoT ssid. I've reduced nightly reboots to 2x per week and may consider disabling that altogether to see how long it goes.

After getting to 37500 and factory resetting, my router did still experience maxed out CPU's, thermal issues, and rebooting - I gave up on it and am returning it now, just doesnt seem worth it. Hate going to TP-link with the pending ban but cant deal with inconsistant internet while hopeing asus gets ontop of this.

I've been on 37748 for a bit and ASUS asked me to try 37803. I've got the file but not risked it yet as this is just taking up too much time being a lab rat.  37748 is stable enough but that's keeping most useful settings turned off.  Log file is still a disaster with so many deauth messages (like Feb 19 18:13:55 kernel: WLC_SCB_DEAUTHORIZE error (-30)) it's hard to find any sense!  No thermal and no CPU spikes. Wifi stability remains the biggest failure point.  I have had to put my desktop on awful homeplug ethernet as it's more reliable than the BE92U wifi.  Yuck!

@Aureliannn_ASUS I have already privated mesaged and stated here I am on 9.0.0.6.102_37748 - I have sent you a sample of these errors that continue. I am not about to roll back to an older version and make matters worse.

 A network architecture diagram are you serious?   I have sent all the log files off via the router to your colleague (no reply from her either) - surely your own downloads for troubleshooting are sufficient?  I deeply regret my loyalty to ASUS and buying this device, not fit for purpose. You should be sending out replacements at this point not trying to pick holes in the customers network. My network for what it's worth worked perfectly with my old AC68U.  Better infact as I was able to use my USB HDD, all my nodes and various other functions that I had to disable on this new one.  Did ASUS forget to test this model before going retail?
