Comcast says the move is to help residents and emergency personnel to stay connected during the recent winter storms.
The Wi-Fi hotspots are located both indoors and outdoors in places like shopping districts, parks and businesses.
When you are in range of a hotspot, the network name "xfinitywifi" will pop up on your device's list of available networks.
Sign-in options will appear for both Xfinity customers and non-customers.
Non-customers will need to look for "get connected" section to connect and will need to renew their sessions every two hours.
