I am cutting the cable. Actually I just called Comcast. Cancelled my voice and TV. I will get Extreme Internet (250mbps) plus the modem rental from them.
Is there a list of good options to buy my own cable modem and stop paying Comcast for renting it? Am I loosing any feature/convenience/putting myself at risk by buying my own instead of renting it from Comcast?
Go to the xFinity retail device finder. I use the Motorola that is listed and it is great. Bought it at Best Buy and I do not pay any rental fee. I pay for the 200 Mbps service but get close to 250 Mbps most of the time.
