Improving Comcast modem signal

Where are you located ?

One other thing.

Cable modems have a memory chip to buffer the incoming signal, and that is usually set to the maximum. For some reason yours may not be. If that is the case your modem may not be buffering the data completely before passing it on to the devices in your house.

Simple first, detailed second.

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. 🤷🏻‍♂️
