Why does my CATV co. need to install new cable for internet?
If you have any older RG59 cable, see any cuts in the lines, or if they detect ingress (noise) on the line, they may require that the line be replaced before you can receive digital services on it. The reason is that any problems on the line may cause the device to malfunction, work harder than it needs to, or just not work at all. It’s probably more preventative maintenance than anything, but it will save you a headache or two down the road.
