What is the difference between a modem and a router?
A modem is a device that connects your home network to your Internet Service Provider (ISP), such as Comcast, converting the digital signals from the ISP into a format your devices can use. It serves as a gateway, allowing you to access the internet. Without a modem, you can’t connect to the internet, regardless of how sophisticated your router is.
On the other hand, a router is used to create a local network within your home or office. It allows multiple devices to connect to the internet simultaneously by sharing the internet connection provided by the modem. Additionally, a router often includes features like a firewall for security, wireless connectivity (Wi-Fi), and DHCP capabilities to assign local IP addresses to the connected devices.
How do I connect my router to a Comcast modem?
To connect your router to a Comcast modem, start by powering off both the modem and the router. Then, use an Ethernet cable to connect one end to the Ethernet port on the modem and the other end to the WAN (Wide Area Network) port on the router. Once connected, power on the modem first, allowing it to fully boot up, and then power on the router.
After both devices are powered up, you can access your router’s configuration page through a web browser by entering the router’s default IP address (usually 192.168.1.1 or similar).
