Intermittent higher ping and timeouts

Somewhat recently the latency I've been experiencing at various times in the day latency spikes from a sustained 10-20ms to sudden and short spikes of 100-300 and sometimes there are timeouts.
Though I live in an apartment complex, the internet was pretty reliable and stable for years. Until somewhat recently.

Mainly I'm just doing a ping -t google.com test to watch the ms as it goes on in the day.

When the issue was going on I also did a tracert and every time I did I would see the first hop outside my network take 100+ms to respond.

When the issue wasn't going on and I did a tracert the response of the first hop outside of my home network the response would be ~10ms.

I own my own equipment and don't rent anything from comcast.

I've tried restarting each node multiple times:

Modem: Motorola MB8600

Router: Tp-link AX3000

I recently replaced my old router with this tp-link though the problem entirely predates the new router.

ping test looks like this when the issue arises:

I've tried different cables,

checked to make sure everything is seated well.

I lived in a different region at one point that had a similar issue that likely turned out to be someone else on the network causing noise over the line or something. The reps wouldn't ever really tell me what the actual problem was. This process took months of even trying to get it taken seriously. So I'm hoping it might be something else that's easier to take care of on my end before I have to resort to that.
