Cable Card Help

Hi there, @user_bngw4c! Thanks for reaching out to us here on the Community Forum. We can certainly try to see if we can help get your Cable Card working, but as you mentioned, support is limited. If we can't get it to work, we can also discuss alternate options. Please send a direct message to us by clicking the chat icon in the upper right corner of the page, click on the pen and paper icon, then enter “Xfinity Support” in the “To” section. Please include your full name and complete street address.

I have a similar problem, except that I never made any changes to my plan when my cablecard suddenly stopped working recently.   Customer service by phone was unable to fix it, and they mentioned nothing about ending support for an existing card (without changes prompted from my end, or otherwise).  They ended up sending a tech which assured me that Tivo/Cablecard was no longer supported, and left an X1 box I'm using now ; I agreed, as I didn't get any inkling that Comcast would make any further effort to enable my continued use of the cablecard.  Finding the X1 interface substantially worse than Tivo's, sadly.  

Would be nice to get a consistent message from Comcast, and express disappointment on this move and poor communication to users.
