Few weeks ago some storm was passing. Before it actually stsrted to Rain, for few hours, when it was incomming I observed my router was restarting every few minutes. For few hours. It really drove me mad! But I realised this router might be susceptible to interference - from air or from power grid. Unfortunately, I have at home no professional tools to measure it 😞 However, I have decided I will try to eliminate at least one - interference from power grid. I have bought this ups:

Which as per description, it should have good filtering of interferences from power grid (IF it really has 😂). 

I have connected it last Friday by replacing original tp-link power supply with this mini ups. During the week I have observed no restarts. I thought it helped but yesterday I have observed it 3 times 😞

I have really strong feeling these restarts come from the cellular module. At my home the cellular module is a backup. It is shame it causes restart of the whole router.

Hi @piotreklc60 
 

I have the same problem. Have you found a solution? 

I also have the feeling that it is related to the cellurar module. Since I changed the setting to 4G only, the router has been running much more stable. But I still have these reboots like you described.

I have recently update firmware to version 1.2.0 and it didn't help. I have seen some dsts without restart but this Monday I hace observed restart when I was on a Teams call 🙈

I didn't know there is newer version 1.2.1 - I will try to update to it.

Generally, it is a shame that TP-Link is not able for such long time to avoid these restarts. It has been reported by many people and they did nothing effective with it. Before X50-5G I had regular X50. It worked many days without restart, my fiber WAN receiver hanged after a month of contineous work whilest X50 still worked. Then I had this stupid idea that if it is working so stable them maybe upgrade my network for a backup (I had some network issues from time to time). Then I bought X50-5G...

For X50-5G I have set daily restart at 3am but it didn't help. I thought that maybe power grid interferences or radio interferences cause it (during some stormy day I had these restarts contineously fow few hours, every few minutes!). I have bought mini UPS but it didn't solve the issue (maybe helped but just a bit - restarts are now not every day but once per few days or it is just some lucky coincidence).

If cellular module must be restarted because of protocol issues then I don't understand why whole router must be restarted with it (especially when 4/5G is working just as a backup). I am embedded SW engineer and I understand that if cellular module is integrated inside the main MCU then it is more difficult to restart only part of the SW because of many depedencies in SW framework. But if the MCU is not such horribly designed to have depedencies on the HW level it is still possible!

The solution was to purchase another router (SonicWall commercial-grade hardware) and set the Deco units to access point mode, disable all advanced features, and switch to a different brand. The support for this product is nonexistent. All of the "special features" that initially convinced me to buy these units don't work, and the system frequently locks up, requiring me to unplug and replug the power to get it to work again. Sometimes, I had to repeat this process multiple times before it recovered. Eventually, I had to purchase different access points to resolve the issues.

I’ve encountered so many problems with the Deco units that I’m now advising everyone to avoid them—unless you don’t understand the difference between routers and access points. The saddest part is that I would have been better off both financially and time-wise by investing in pro-grade hardware from the start, instead of dealing with the Deco units (3 x55 and 2 x55-Outdoor). Before that, I had 4 x M5 units, and they were warm to hot to the touch, even when sitting on a table with plenty of airflow. Poorly designed, they needed ventilation slits on top to allow hot air to escape. I was worried they might catch fire. A properly designed product shouldn't get that hot during normal operation.

That said, if you're a fan of TP-Link products, I would recommend getting a TP-Link router, disabling the Wi-Fi, and setting the Deco units to AP mode. The hardware and firmware just can’t perform "as advertised" when trying to do both jobs. I also had my Deco units hardwired with an Ethernet backhaul, and it didn’t seem to improve their performance. If you want a performance boost, ditch the mesh altogether. It sounds great in theory, but it does take a performance hit on the network.
