I have a problem with the router on my WAN port it's turned off every 1 hour, can you help me? This is my log from the router : Hardware Version: Archer C1200 v3.0 Software Version: 3.0.8 Build 202112

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
