Modem needs reboot every 2-3 days

My download speed drops to 20-30Mbps after the modem is on for a few days. A modem reboot fixes this, but problem repeats again after a couple days (sometimes only hours). 

Xfinity support said signal was fine. I replaced the modem with a brand-new xfinity compatible modem, issue still remains. No idea what to do now.

I tried multiple devices and the issue remains. I also tried removing a cable splitter that was in the line and also redoing the coaxial connector, but also didn't work. No visible kinks in the wire where I can see. Still haven't identified the problem.

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 copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.


What is the exact make and model number of the modem / gateway device ?

Is this a WiFi connection ?

@XfinityZacharyA 

Why must this have to go private right away ? That kind of defeats the purpose of a public help forum such as this is, no ?... Why not ask some general self troubleshooting things first which is in keeping with the intent of what these public help forums were designed for so that all readers here may benefit.

Signal looks stable for the moment after several days. Confirmed modem signals were all within range.

The cabling was likely the issue. I assumed my tinkering failed, but now it looks to be holding up well after several days. Redid the end connectors where the outside and inside cables met (it was basically stripped before) and removed the splitter to unused wall outlets. Seems to have done the trick. 

Thanks for your support.
