Advertisements I recently purchased a new cable modem (Netgear CM2050V) that I would like to activate. I'm afraid of the CableCARD situation with the FCC and Xfinity not activating them anymore. A few years ago, I switched cable modems and they accidentally knocked out my CableCARD. I had to call to reactivate it (it went out 24-48 hours later). Has anyone changed cable modems over the last couple weeks and if so, did it affect your CableCARD? I certainly do not want to cause the demise of my TiVo no sooner than what will occur naturally.
