Two ISP’s, one house

One modem/router is hooked up to the phone outlet in the wall another modem and router is hooked up through a coax cable cord the screw on one. My question is will they interfere with each other? Are they is line that goes through the wall and the white cable cords connected to each other?

The only "interference" they could create would be WIFI interference with each other if they are on the same WIFI channel.
