As I recently warned, however, you shouldn't need to lease an Xfinity modem from Comcast to take advantage of the faster speeds. In fact, you shouldn't have to lease a modem at all. Why is that important? Because your cable modem may be nearing the end of its effective life.
In my case, for example, my Comcast-branded Motorola Surfboard SB5101 cable modem is only rated for up to 30 Mbits/s down — enough to handle a 25-Mbps connection, but not capable of handling the 50 Mbits/s that Comcast now offers. I'll need to upgrade.
In any event, Comcast is busy trying to buy Time Warner Cable for $45.8 billion, and trying to convince regulatory agencies to let the deal go through. Comcast has upgraded its consumer services roughly annually. But its recent upgrades to its service in Washington D.C. and tech-friendly California come at an opportune time.
