You also have the option to switch this public-hotspot feature off even though
Here's what you need to know:
-- The modems. Certain newer broadband
If you are not certain if your device has these features, you have a couple of ways to check this.
One is to search for a Wi-Fi network called "xfinitywifi" in your vicinity. If the network's signal is strong, it is likely emanating from your router.
Confirm this by logging in to your Xfinity account at customer.comcast.com. Click "my account" at the top. On the next page, click "users and preferences" at the top.
On the next page, look for the "service address" section, and see if a "manage Xfinity Wi-fi" link is immediately below that. If it is, you do have a home-hotspot option. Clicking the link leads to a pop-up control panel for turning the home-hotspot feature on and off.
-- Wireless networks. When you have the home-hotspot feature turned on, your wireless gateway is sending out two Wi-Fi signals. One is for an "xfinitywifi" public wireless network. Any

Your wireless gateway's second Wi-Fi signal is your private network, accessible to you and any others given permission to use it. You can set whatever network name and password you wish. Do so, on a computer physically linked via an Ethernet cable to the wireless gateway, by typing 10.0.0.1 into your Web browser's address field. You'll be prompted to log in using your
This leads you to a modem administration panel with a range of controls (many of them a bit too geeky for average mortals).
To change your private Wi-Fi network settings, click "gateway," then "connection," then "Wi-Fi." Look for the "private WiFi network" section near the top, and click "edit." That is where you can change your network's name and password, and optionally prevent your private wireless network from being detectable by nearby computers and mobile devices.
Roaming access. When you are away from your home, you can use your smartphone, tablet or notebook computer to access any "xfinitywifi" public hotspot.
Many of these are located in businesses, such as grocery stores and medical clinics. Browse a directory of such business-based public hotspots at hotspots.wifi.comcast.com. Type in an area code to find Wi-Fi networks near you.
Xfinity home hotspots aren't listed in that directory, but you might stumble on them as you walk or drive around town. You're free to use those networks, but try not to be too creepy about it. (If you are standing directly outside someone's home while intenely tapping on your phone, tablet or laptop, that is probably too creepy.)
Nearly 1 million Xfinity public hotspots are available around the country, according to
An additional 100,000 or so public wireless networks are available to Xfinity users via
Those public Wi-Fi hotspots are identifiable by their shared "cablewifi" moniker, and accessible with your Xfinity credentials just as "xfinitywifi" networks are.
