AX12 RAX120 Constantly Rebooting
For the third time in a year, this router has started to reboot itself about 10 times per hour. I have 50+ wifi/wired devices connected. Current firmware v1.2.3.28 installed over 3 months ago. No ...
- The last time this happened, I did do a factory reset. No help. That time I was inside the return window so I sent it back for another one. That’s the one I have now and it’s been solid for months since it too had the problem twice. Ruling out a defective unit. Update: I unplugged it for the overnight. Powering it back up in the morning, it’s been solid once again. Definitely a heat issue. I also have a mesh that records traffic to each connected device. One tablet running a surveillance camera stream had used over 7.5GB 2.4mhz streaming over a 2 hour period just before this started. I’ve disabled 2.4mhz WMM and the home assistant card responsible for the streaming. No more problems. Bottom line, this router cannot handle 2.4mhz streaming video. It will overheat.
I agree disabling 2.4ghz wmm significantly decreases speed on that channel but I'll take that over the router constantly rebooting.
The real fix for me was swapping my modified sine wave UPS with a pure sine wave UPS. Im going on 20 days without a random reboot with 2.4ghz wmm enabled.

UPS devices with PFC/APC / Line-Interactive should correct any power fluctuations on the fly without going to the battery but if you have a crummy power source in a large condo building like mine that UPS will need to switch to DC a couple times a day. How gracefully this power correction or switch to DC happens varies by APC UPS model number seems to matter quite a bit to this particular router.

This is the PFC/APC UPS device I previously was using which I thought was a pure sine wave but in fact was a modified sine wave which was causing my RAX120v2 to randomly rebooted 8 times a day if I left 2.4GHZ WMM Enabled. With 2.4GHZ WMM Disabled the router was much more stable but I think it still rebooted like once a week?

This PFC/APC UPS I switched to is pure sine wave and let my router run 20+ days in a row with the 2.4GHZ WMM Enabled. I had a cable internet issue at one point where Spectrum internet was down in LA one day so I did a manual router reset and the system has stayed strong again with no random reboots so it sure seems like this was the root problem for my router.
