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.

Reach out to ASUS or messege one of the Mods here. They'll send it to you.

TBH the router is performing ok.  I dont like the occasional slowdowns but they actually might not be the router.

This beta hasn't really changed anything for me (they said it wouldn't resolve the thermal reads and it hasnt). The thermal alerts are a data read not a temp issue, the CPU on the main in use processor is still flapping between 40 and 90% utilization but otherwise it seems like a decent piece of kit.  I prefer it hugely to the Eeros and I have eliminated the crashing I had with the netgear.  The thermal issue is cosmetic (but annoying because I think its driving the CPU and writing to the logs) but not critical from what I can see.

I am not having much hope on Asus actually putting out a new firmware before my Best Buy return window is up (about a week away).

I took one of my old Asus routers, an RT-AX3000 config file (after a hard reset and minimal config set) and loaded it into the RT-BE92U. I figured it could not hurt.

The CPU seemed to stabilized and the "thermal thermal_zone0:" errors went away.  Still a little laggy going through settings tabs though.

My main problem has always been that RT-BE92U reboots itself randomly, usually every couple hours and thought the thermal errors might be contributing to it (I’ll see if it Uptime is longer than 2 hours tomorrow morning). 

I am using it in a test environment now that only has 1 intel BE200(wifi7) client connecting and it has been about a week now and I still have not seen the Uptime over 2 hours. 

For the people that are losing connection I have read, is it dropping connection or is it rebooting itself also?

I will still take mine back if an official Firmware is not released soon, I don’t see a reason to sit on it until it is usable.

I currently have a RT-AXE7800 that has 40+ clients on it, mostly home automation stuff that does not reboot itself or lag or drop clients, and actually works quite well.

I wanted the Wifi7 connection bandwidth increase on 6GHz band, but I can wait and buy the RT-BE92U again in a few months if they fix/finish some of their firmware issues.

@titan04 Scroll back through the thread.  I was given permission by Asus support to share the link to 37803.

@cowhow Ah, thanks.  Found it in another thread.
