NEW YORK ( TheStreet) -- Four years ago, I was stuck in Chengdu, China, facing numerous deadlines back in the United States.
My solution was to turn on my computer's WiFi router, look for open connections among my new Chinese neighbors and piggy-back on them.
It worked. My copy made it to where it needed to go. I even wrote a story about it. I suggested that a "side-band" could separate the bits a subscriber was using from those the public could access, and the router could firewall a subscriber's computer from those radio signals. Voila -- free universal access to the Internet!
Now, in an effort to expand the utility (and popularity) of its Xfinity cable modem service, Comcast wants to re-educate you. Their new wireless routers will broadcast two separate signals, one to your local network, and the other its other customers can use, according to CNet. There's a catch here, of course. In order to use the "public" signal, you also have to be a Comcast customer. Thus, neighborhoods will be filled with signals the users of rival ISPs can't access, increasing the value of Comcast to those who have it. The company has posted a searchable map of its Xfinity hotspots and is offering an app its customers can use to find them. This is an "opt-out" service, not "opt-in." As soon as you get one of these new WiFi routers for your home network, your neighbors who are Xfinity customers can get free bits from you.
