Laptop keeps losing internet connection?

Hello
My MSI GE72 2QD keeps losing connectivity to the internet.
I connect wirelessly and the internet will work fine for a few seconds/minutes until not connecting, even though the WiFi sign is still normal.
What I've also noticed is that when downloading something without other internet interruption, it will do just fine. But as soon as I go to a website it will literally drop to 0.
How can I fix this?
 
Thank you so much for replying!
I read the article, and while I tried my best to understand it, I found it a bit hard to fully understand what I was supposed to do on my case.
Do I set the MTU to1492?
Cheers
 
1492 will do the trick, but just know there are better numbers if you take the time to find them.
