I was surprised when Comcast wanted to swap out my modem for an all-in-one modem-wireless router-phone hookup. And to boot more than doubled my speed from 20 to 50 mbps or better at no cost. Cool. Then I notice that all of a sudden I see Xfinitywifi show up as a new UNSECURED wireless connection. Obviously from my new rig as it has 5 bars and my closest neighbor shows up at 3 bars. Then yesterday I got a letter from them telling me all about the new Xfinitywifi service available at thousands of locations. Apparently also out at the street in front of my house. All of a sudden I get this big brother feeling. They say it doesn't affect my internet speed as it is a separate signal, but admit it could affect my wireless speed. To their credit they do say it can be disabled. but how many are going to bother? So for the price of a faster connection they are using my home as a WiFi hot spot for any Comcast customer with a username and password. I have to admit I have real mixed feelings about this.
