I bought RAX120v2 two weeks ago. It was restarting on random basis from the very beginning. Somedays several times daily, somedays several dozen times dally. I have tried everything described here, but none of that helped me.
My observations during restarts:
- It is not adapter issue. I'm living in Europe and have an European adapter version, but the router is still restarting.
- It is not a heat issue. Yes the sensor shows NaN, but it is just a problem in the UI. I started 4K YouTube videos on eight devices in parallel and the router's fan was working during the load. The temperature sensor was OK and the router was not too hot. Actually the processor load was ~40%.
- It is not a settings issue. I've tried them all, without any success.
Even after one hour playing of eight parallel 4K YouTube videos the router was pretty stable. Then I moved to another room in my home, returned after 15 minutes and the router was restarting ...
That was my experience last two weeks. Now the good news from the last several days. I'm using ESET Smart security. Sometimes I got notification for a DoS attack from one specific device. It was my home security camera which has motion detection. Then I realised that the router is detecting the same false DoS attack and it cause the restarts. Almost every time when I move from one room to another, the camera triggers false DoS attack and restarts the router. I have detached the camera and now the router is running smoothly without restarting itself. I'm not using any cool pad and returned all my previous settings. I'm using Smart Connect, WMM and even 160MHz band. Everything is perfectly stable. The problem was in my camera. It can be connected with LAN cable or using WiFi, but seems that both are working in parallel. In my case the camera had two IP addresses, one for the LAN port and one for the WiFi. I decided to reset it and connect it again, but using WiFi connection only. I refreshed the router DHCP table and connected the camera. Now everything is running without any issues even with the camera. Actually the router is perfect when it is stable. ESET Smart Security doesn't report DoS attacks as well.
All of you, who experience such kind of router restarts, should check for DoS attack in the router's log or in the your security software log. If you have such
kind of attacks, find the device which is causing them and disconnect it from the router. Then check the router stability. It is pretty common issue regarding NG routers to restart because of false DoS attack. You can try to reset the problematic device and connect it again to the router. In my case it was working solution.
Currently, the router is working almost two full days without a single restart for the first time in two weeks.
