random ping spike issues for almost a month now

Dealing with random ping spike issue. Faster Melee ppl told me it's random but I want to find further information to see if it's true? I'm wired, my rig can definitely run it, I've restarted my modem and router and even bought a new router. I've triple checked my settings, everything. my internet speed is way better than enough to run it. What is the solution?
