An Internet router is a device which connects two or more digital networks to enable the transfer or "routing" of digital data.
Unlike a modem, a router does not convert digital data to analog signals and analog signals back to digital data. It simply transfers data from one digital network to another.
A router can be connected to multiple end user devices. The Internet routers supplied to customers of Swiss telecom service providers typically include 4 ethernet connections, allowing up to 4 devices to connect directly to the router. Today, consumer routers generally include built-in WLAN functionality.
Most Swiss broadband service providers include the use of a router in their broadband plans. Some service providers let you select a router of your choice.
