Xfinity Speed keep dipping every minute or so
Whenever Im using my internet It dips sometimes from 300 MBPS down to sometimes even totally disconnecting me.
I've worked them a few times to get this fixed, including fixing some wiring, getting a new modem, and refreshing the signal three times, but each time the problem still persists and its making it impossible to do anything.

What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
What is the exact make and model number of the modem ?
Is this a WiFi connection ?

Yeah, those are the router component event logs, not the modem component logs. Don't worry. There is likely no longer a way to get them as we've seen a number of posts here lately indicating that they have been disabled in the supplied gateway devices by them with a recent firmware update.
So the signal stats are o/k but something is going on. Perhaps there is intermittent noise ingress into the line(s) somewhere.
There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They will be able to poll the CMTS to see whether or not everything is in the green zone, see your node / cable plant and modem health, and also see a history plot for the modem. You should get a reply here in your topic. Good luck !
