Improving Comcast modem signal

Detailed: https://www.researchgate.net/publication/224140225_Cable_modem_buffer_management_in_DOCSIS_networks

I totally agree, Comcast is brutal... customer service is a miserable endeavor whenever I need to call in but have found that their routers are fine, in my setup anyway. Maybe this could be all connected better but here's my signal path. I have an xfinity XB Gateway connected by Ethernet CAT8 cable to an Apple AE. That Airport then communicates with a second AE wirelessly in my designated listening room which connects directly (Ethernet CAT8 also) to my Elac, Discovery Streamer. Connection is seemless and works swimmingly using either my iPhone or iPad running Roon and being used as a remote. Elac then feeds a Line Magnetic, 502ca tube DAC then off to the rest of my system. Again, prob other ways to get the same/better end results, but this is a home run for me. 🤷🏻‍♂️

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.

@chungjh   You mention your issue with Comcast is that you have to constantly reset your modem?  What is your normal ethernet speed with the Netgear modem and what version of docsis is it ?  I had a similar issue with a Motorola modem until i updated my modem to docsis 3.0 and i just bought a new Arris T25 (docsis 3.1) b/c i have a gigabit plan and i'm only getting 500mbps on ethernet. Do you also use Comcast phone ?  If so and you purchase a modem make sure you get one with the phone jack(s).  i had the Xfinity/comcast router for a long time but got tired of the rental fee--never had any problems with the currrent Arris router and don't expect to with the new one.

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?
