I have an odd situation that maybe someone out there can assist me with. Within the past few weeks I have been having problems with my house phone and incoming calls. I can see the caller ID on the tv but there is a six second delay when my house phone actually rings. When I look at my Xfinity app, sometimes it will say modem not connected yet I have still use my house phone and internet. When I log out of the app and come back into it, it will show connected. Just don't see how it can be my house phones when they're brand new as of April this year. Could it still be a bad modem even though I just got it in June?
