The amazing power of Comcast

A week ago or so I received a robo call from Comcast/Xfinity saying that my current cable modem as too old and it will not support the speed improvements that they were doing with their network. But I was eligible for a free upgrade and I had to reply to some mail that I was going to receive or go to some website for more information.

When you receive a message implying that my internet could be faster, of course I complied and requested a new cable modem. And that cable modem arrived yesterday.

Before I installed it, I decided to do a speed check and then compare with the speed of the new modem. Surprise: nothing changed! I still have 30Mbps down and 6Mbps up after installing the new modem (which, by the way, is about double the size of the old one). So, besides the size, what is new? A couple of "Trojan Horse" things:

  1. Support for their phone service: if I decide to use the Xfinity phone service, I don't need a new box, they just need to activate it and I connect a phone to the back of it and I'm good to go.
  2. Expansion of their "free" WiFi system: basically everybody that has their router receive the ability to have an "xfinitywifi" network. I actually don't care too much about it. I do believe that they could have gotten the technology right and create an isolated network that does not use the same IP that I have and will not affect my bandwidth much. My concern with it is:
    1. It adds even more WiFi networks around me - see the list below
    2. It's not trivial to turn it off. I can't even turn off the WiFi that comes with it to use internally. I already have WiFi at home and I spent a lot of time having to expand my network to put the WiFi in a place that the whole house is able to work, and that's not anywhere close to where the cable modem is.

Thanks, Comcast...
