No change, about 4 hours after the beta update it happened again.

@Kevin_Z 

Bought it April 2019 (so it is stil under warranty).

Noticed it maybe a few months ago first, but it was rare enough at that point didn't bother at all. Now it happens several times per day. No other changes to the network itself.

ISP (Telia Finland) modem is Thomson TG789vn, Archer is in access point mode with three devices connected to it via LAN ports. Wan connection comes directly from the Thomson. There is also a plain 8-port gigabit switch in the same network.

Should mention Arches is sligthly warm to touch, but by no means is it hot.

I have the same problem, todays reboots itself 4 times in 2 hours. I've updated with beta. Will check if it fixed ranbom reboots issue

After some testing it was great with beta firmware, but today something strange happens. Router shutdown and was not responding about 5 minutes. I've checked power supply but it was ok. Then after 5 minutes of shutdown it start itself. Strange, what is wrong??

2 weeks past by. So far no random reboots. There will be stable version of this firmware?

@0kti I have updated the router today with the BETA version, I am expecting it to help me as well. But we need a stable release.

@Kevin_Z 

Another 2 weeks past by. For me beta firmware is stable.

There will be stable or our router is abadoned (too old).

I'm still facing this issue with my Archer C1200 v2.0

When my WDR3600 died after 4 years of duty without any issues I got a C1200 V2. The newest firmware version was installed instantly via the auto update (it's the same as on the website, I checked) and it was set up properly. However, it reboots randomly - not very often, but still. I have encountered it about a dozen times during my first year of ownership now and it is really annoying. There is no heavy load on the device at all, my internet is only 20/5 Mbit and there is only one PC wired to it, and one PC / one tablet / two mobile phones via WLAN - but never at the same time, usually it's only one mobile phone using the WLAN.

 

I have no explanation for this and recently it rebooted while i was in an online multiplayer game, which is simply unacceptable. It just happened again today when I was lying in bed, surfing on my mobile phone like I've done thousands of times before...I don't know what's wrong with this device but I am kind of sick of it by now.

 

I have searched this community but I did not find anything recent about it, only with old firmwares for V1 devices. Does anybody have similar issues or even solutions?

. Does any find the solution ?.
