I was just sent a "New" cable modem since I changed and upgraded services. It is the Cisco DPC3941T. I have not hooked it up yet because I am concerned why Comcast has sent me a modem Cisco no longer makes and when they did, it was considered at the End of Service. I understand that Technicolor had bought out that division and now makes a similar model which I suspect has upgrades. I had also read that this particular modem had some hacking problems. Can anyone explain to me why I was sent this particular modem and why it is ok?
