Improving Comcast modem signal


Our internet service is Xfinity/Comcast or Verizon. Currently I have Comcast service and use their modem because I had trouble with Netgear modem compatibility with Comcast. The problem is that the Comcast modem doesn’t allow LPS. I don’t know about the Verizon modem. So, for people with modem tweaking experience, any suggestions that will make a notable improvement?

The modem is connected via house Ethernet cable to EtherRegen in my listening room, which is connected to Lumin X1 streamer via fiber optic listening room.

That (pictured above) is exactly what was installed when I started my xfinity/comcast service a couple months ago. I mis-remembered that it had an internal power supply. My mistake.

@oldhvymec no noise whatsoever. It's actually on a separate circuit and besides my dedicated listening studio is grounded with a wonderful grounding device. Noise floor is basically non-existent.  

The one that I have has an internal power supply. Sksos, what grounding device are you using?

@chungjh yes my modem/router has the internal power supply. As for the grounding box, since I'm a dealer I don't promote it on this site, feel free to PM me.

Thanks. I don't have any noise now with 93% efficient speakers. No mater where I plug mine in the with an external PS it has a ground loop issue. The only piece of gear that does that. It's less than a year old. Great transfer speeds with Cat 8 from Cat 5. The GL eliminator shut the stupid thing right up. 

I've tried 3 of the neighbors PS too. Same thing. You should hear it with Klipsch 103s they will run you out of the room. Neighbors rig.. GL eliminator fixed it right up.

Thanks Ay..
