I've seen some sketchy cat 5e cables.

Yes, I've tried connecting to 3 different computers in my house, using different cat5e cables too.
Last night I tried testing connections from all 4 ports, connecting to port 4 was the fastest but is usually around 200-300 Mbps, far from my 1200 Mbps package speed.

I recommend trying CAT6 lan cables. Would perform better than 5e.
Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.

signals don't look to bad.
What computer do you have connected you're testing with?
What website are you testing on?
