Xfinity routers are equipped with two antennas. One is used to broadcast a private network signal based on the selected plan; second — broadcasts a separate public network signal that can usually be seen as an xfinity wifi hotspot.
This second signal allows small business owners to offer WiFi to their guests without sharing access to their private connection. For security, Comcast allows only 5 people to be connected to a single Xfinity hotspot at a time. If you are a Comcast customer and have signed up for XFINITY Internet, you’ll be able to access all Xfinity WiFi hotspots free of charge.
