Very interesting idea. I'm on cable as well, but oddly on my internet service I have Gigabit DL speed with 30 Mbit UL speed (that consistently tests at 40 Mbit). I realize that the phone service probably rides on its own separate frequency channel (s) that have nothing to do with the internet channels and TV. At any rate, I've had Cox techs out numerous times in 2023 trying to improve signals to my house when my cable TV DVR and satellite boxes, which were all coax cabled, would frequently fail to boot due to poor signals. Eventually we went to a single coax cable serving the new Panoramic Gateway with all Cable TV boxes connected to it via WiFi. All coax splitters, signal amplifiers, etc. were removed since no longer needed, and they even did some work on the pole to improve the incoming signal. Once that was done, the Internet and TV have been spectacular - better than at any time in the last few years. But alas... the phone service (which previously never had an issue) started acting up recently. I will have the tech here tomorrow and will go over everything with him and see what he finds / does. Will be sure to post an update if he fixes the issue. Hang in there.
