Comcast setup internet

When you subscribed to Comcast's service, you either received a cable modem and its associated equipment, or opted to use your own mode. Whenever you get a new computer, Comcast recommends that you run through the Internet service process again. This ensures that your new machine is configured to use Internet service.

The set up process is a simple one. The process is the same whether you have a modem provided by Comcast, or a third party one. Insert a coaxial cable into your cable jack. Insert the other end of this cable into the Comcast cable modem. Plug the modem's power adapter into the power port on the modem.

Plug the other end into a wall socket or power bar. Turn the modem on, if it is a model with a power button. Your modem may take several seconds to acquire its connection to Comcast's service.

Plug an Ethernet cable into the Ethernet port on the modem. Plug the other end of this cable into your new computer's Ethernet port. Place your xFi Gateway at least three feet from the ground and avoid cramped space. Confirm that all cables are plugged in.

Unplug your equipment, wait a minute and plug it back in. However, there are some cases that require professional installation, such as:. To change your Xfinity Wi-Fi network name and password , either login into your online account or download the Xfinity xFi app. If you have any issues during self-installation, feel free to contact Xfinity customer service to get help or visit their support center online.
