Changed my modem (TEC TC8305C) on Wed to another one (AR TG862G), connected it and everything was working okay.

Checked yesterday, and I have no phone service, logged in to my account and it has the old modem up along withe new one.

Did a reset and power cycle, no changes. Also tried swapping  telephone ports nothing changed.

Just trying to offer up some thoughts based on what I did several months ago when I changed out my cable modem with telephone ability.  I leased the original modem from Comcast and did the same with the new modem I currenty have.

 

When I took the original modem into the cable store and got the new one, a different brand and model, they gave me a phone number to call to activate the modem.  I was told to hook the new modem up and give it about 15 minutes before calling to activate it.  I did that and then called the number to activate it and a few minutes later everything came online inclucing my phone.  

If I recall correctly, my original modem showed up on my account as not connected until the next billing cycle along with my new one which to me made sense since I was leasing each modem through Comcast.

 

If you went through all the steps given if it is a leased modem, then it could be that there is something wrong with the telephone portion of it and I could only suggest returning it to the Comcast store to swap with another unit.  

 

Hope this helps you out.

mad876max, it sounds like the newer modem isn't fully activated. I can double check. Please send me a private message (Click ComcastKenF and then click Private Message Me) with your account address and full name so I can see which one is physically on the account.

Hi, mad876max - I removed the old modem from the online view. You should no longer see it under My devices webpage.
