I have no dial tone and have tired the following:
We returned from vacation and the phone line was "Line In Use". Unable to disconnect via the phone, I unplugged the phone line running from the modem to the phone receptable. I now have no dial tone throughout the entire house. The phone does however work when plugged directly into the modem. Next I checked the land line wire connects and all were secured. Thinking I might have a wire issue and given each of the phone line is independently wired thru the same hub, I then connected to a different phone receptacle and still no dial tone.
Although the phone works connected directly to the modem, could I still have an equipment issue. I'm at a loss given it appears nothing is wrong with the hard wiring in the house.
Also I did use the Comcast App and nothing came up
