Getting disconnected from games every few minutes

Hi,
I am using OpenWRT on Netgear R6220, Connection is PPPoE which is dynamic.
Whenever I play any game like CSGO or any other online game I get disconnected every few minutes at first I used to get completely get disconnect from the game but I came across a solution that when I changed LCP echo failure threshold and LCP echo interval from 0 and 1 respectively to 12 and 12, I no more get thrown out of server, instead my game freezes and I experience rubber band effect. This happens with every single game.
I am very new to this firmware so I don't know much about it, any help would be appreciated.

You could run ping command (to both the game server and some other server--1.1.1.1 for example) simultaneously to see if your whole connection drops the same time the game freezes, or if it's just your connection to the game server.

The freezes when the connection drops, and in 2 or 3 seconds it comes back online and the unfreeze but I experience rubber band effect. This happens to every single game, maybe some router setting might fix it.

Your entire internet connection is going down, this is not just about games. I would have a look to the logs, and see if there are messages when the drop happens.

This seems to be the problem the connection always drops for 3 seconds.

This is strange, there are no PPP messages in those logs, is the PPPoE connection being controlled from another device (like a modem router provided by your ISP, for example?).

no it is on this device only

How is it connected to the internet?
