Comcast is making a generous offer until July 4th: use their WiFi network free:
Comcast promises that you can access over 100,000 hotspots just by looking for the XfinityWiFi or CableWiFi network name on your list of available networks. How can Comcast have so many hotspots?
You, the Comcast customer, are providing (many of) them, probably without even knowing it. According to published reports, new Comcast routers have two channels: one for the WiFi signal in your home for you to use, and a supposedly separate one for the public (or other Comcast customers to use). They say you won’t be charged and your service won’t be degraded when others tap into your Internet connection.
And to add insult to injury, you allow others to tap into your router by default, unless you affirmatively opt-out.
While the public is invited to tap into your router until July 4th (and for just two hours after that), in the future only other Comcast customers will be able to.
How do you feel about sharing your broadband Internet connection with strangers?
