Improving Comcast modem signal

@fuzztone, Does Comcast have a range of modem quality?

Has anyone noticed a significant improvement with an LPS for the modem?

@mitch2 I tried Netgear modem with my Comcast system and I could not get my internet to work. So, I had to go back to the Comcast modem. May be the gigabyte capacity of Netgear conflicted with Comcast?

I hear a lot about the Ground loop issue. What is the problem it can cause and how can I deal with it?

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

Does this mean the Verizon fiber optic system is better than Comcast cable for digital systems? 

I will call Comcast to get their newest modem. 

I have to reboot my modem once a week due to loss of internet signal. While streaming, I frequently get “network error” on my streamer and music breaks up. I can only assume that the internet supply is inconstant.

Because the sound quality late at night is so much better than during the day, the rate limiting factor is not my equipments but cleanliness of digital input and power grid. I will start a new thread to see if it is worth switching to Verizon. Thanks everyone for valuable insights.

My ethernet speed is 25-125 mbps. I am using an old Apple router with Comcast rental modem. 5 years ago, I bought a Netgear modem (I don't remember the model)  to replace the rental modem and it never gave me wifi signal, so I went back to Comcast. I don't use Comcast landline phone. I am going to try to get a new modem. Do you like Arris > Netgear?
