I’m in Houston in an apartment using Xfinity and I’m trying to figure out if this is normal or not.

All my tests come back perfect — A rating, low ping, high speeds, no packet loss. I’ve had multiple techs come out and they all say everything looks good.

But in actual gameplay (COD, Overwatch, Fortnite, 2K, even single player), I get random latency spikes. It’ll be smooth at ~20ms, then jump to 80–120ms for a second, then go back. It happens constantly.

I ran a bufferbloat test and caught the same spikes there too, so it’s not just in-game. The connection isn’t slow — it’s inconsistent.

The hardest part is it’s intermittent. When techs test it, everything looks fine. But during real use, it’s unstable.

I’m starting to think it’s node congestion or routing changes, especially being in an apartment. It literally feels like the connection path changes mid-session.

Has anyone else experienced this with Xfinity? Is this just how cable behaves under load, or is there something that actually fixes it?

Not looking for basic troubleshooting — I’ve already done all that. Just trying to understand if this is solvable or not.

I’m not talking about average ping, I’m talking about jitter spikes affecting real-time input.
