Intermittent Lag Spikes - Time Warner Internet

This question is about "Intermittent Lag Spikes", with Time Warner Cable internet and apps. I've been having lag spikes every couple of minutes whenever playing any game for a while now. Internet is fine for streaming but playing a game for 5 minutes without a lag spike is impossible. I tried wired and wireless both have the same problem. Got the modem and router replaced a couple months ago for slow internet and now this.

Modem is Technicolor model number is E31T2V1

Router is Sagemcom model number RAC2V1S

Speeds tests show 469 mbps download and 22 mbps upload
