Weird Internet Problems

Hey guys, I don't know why, but I've been having random lag-like issues in game. I will be walking or shooting, or something like that and I'll teleport backwards to where I was just a second ago, but none of my team, or the other team see's it. I don't think it's my ISPs fault, because my ping is still very good, or atleast what it has always been, (About 10-25 on CS:GO, and about 80 on LoL. I live on the east coast) and this happens on Counter Strike and LoL, it might happen on other games, but I don't play too many other online games. I'm really not too knowledgeable when it comes to internet-related things. Thanks for any help.

it could be your isp router melting or/and your on wifi.
