My Router used to work very well when it is new (now it's just 3 months older). But recently whenever there is a power failure, router doesnt connect to the internet and I have to switch it off for 10 mins and plug in back the ethernet cable. Now this happens even when there is no power failure. I checked with ISP and there are no issues with the broadband team. That is when I found the logs of router, it is always kind of getting reset and internet connection is lost. Below are the logs which got reset. And this is happening very frequently. How to resolve this?
