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.

Their latest modem uses an outboard power supply   It’s white and square. Not sure of model name/number

I believe this is what Xfinity supply as standard these days.

Are there any other current models, or is this it?

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?
