I'm constantly loosing internet connection, and everytime it's a different problem.?

[squarestar786]

Okay, so, since yesterday, I noticed my internet connection went on vacation, so I did the usual: Unplug modem and router for 30 seconds. (Maybe more). However, this happened around 3 times in the same hour. It then worked fine for the rest of the day. Now today, it's happened about six times. What I notice, is that it does fix itself when I unplug, but everytime there's a new problem.

There was a "The DNS server is not responding" one that came up 3 times though.

But just now these happened.

I'm not a tech--whatever you call them.

So naturally I don't understand what the fuck any of this means. What is the DNS server?
What does all of that in the screenshot mean?

And how can I stop from loosing internet connection?

Thank You.
