Windows 10: Internet disconnecting while playing certain games

This problem has been occurring for a year now, I once fixed it by messing around with the settings and the other time It was fixed by a computer maintainer, but recently, it came back for some reason, and it is very annoying. basically, what happens is that my internet disconnects when I play certain games, even if its singleplayer. I don't know how to explain this, but my internet completely dies, and I won't be able to make it work unless I restart my computer. And I doubt the problem is from my router because after the internet disconnects to me, the router doesn't. even if the game runs smoothly without a problem, internet still dies. and sometimes when I play games that work fine and try to stream them, the same thing happens after like 10-15 minutes. Can someone please help me? I'm really desperate.

Internet disconnects frequently while playing steam games

Yes, I can confirm that both the computer which I am starting the game on, and another computer, gets a Ping Timeout.

What happens is, i start the game. As soon as i do anything that interferes with the internet (e.g. loading up the Servers list to join a game, or sometimes i even get into the game, but gets disconnected too quick for me to start playing)

 

Internet disconnecting when playing online games

My internet which is connected to the school is disconnecting when i play online games on my desktop. Browser games work fine but games that need installation like league of legends and fortnite disconnect every few minutes or every 30 minutes, it is random.
I can watch twitch, youtube and browse with absolutely no issues, i can watch on good quality. My ping is usually fine when i play these games but i just disconnect at certain times. It might be because my DNS server is not responding but ive searched how
to fix that issue and nothing happened. Please help

 

My wifi disconnects when playing certain games.

I have no clue when it started happening. Whenever I play certain games on my laptop like lets say fortnite, rainbow six siege, valorant, etc. My wifi suddenly disconnects after being in the game for about 5 minutes. I have no clue why. However if I play
minecraft or Among us, the wifi is stable. I have already tried updating my wifi wireless driver, it is up to date, but it still does not work. I still get disconnected. If anyone can help I would really appreciate it. I would love to play the games that I
used to enjoy playing. I am unsure if its due to a windows update or driver update. I tried rolling back and picking out previous wireless drivers but those don't work either. Thank you to whoever decides to help with my problem!
