If you live in Houston, Texas, and have Comcast Xfinity for Internet, your house is now a free Wi-Fi hot spot. That's right, Comcast activated open Wi-Fi on 50,000 Xfinity modems a few days ago. It's planning to roll out the same thing across the country in upcoming stages.
Any Comcast user can connect to the Wi-Fi network - the name is "xfinitywifi" wherever they are and non-Comcast users can use it for 10 minutes.
Naturally, this raises some security concerns. Comcast says that the free Wi-Fi and your home Wi-Fi are completely separate, so no one can get on your network.
I'll buy that. Many high-end routers can create multiple separate networks for security. Learn about other features you might want in a new router.
However, Comcast also says that this won't impact your Wi-Fi speed or Internet speed. I'm not buying that. True the free network is limited to just five users, but there's still interference possibility and they're using your Internet connection. Unless Comcast has a separate connection going just for the free Wi-Fi, something has to give.
