How to Change the Wireless Settings in Comcast Modem Router

Comcast modems/routers/cable gateways are shipped with predefined pass phrases or keys and a predefined name for your network that’s usually something  like ‘HOME-45-4G’. While the default name of the network of SSID isn’t bad, it’s not necessarily easy to remember or easy to find if your neighbors also have similarly named networks from using the same ISP service provider.

In addition, the default passphrase to get onto your network from the manufacturer is usually some wacky word or combination of words. Not only are those types of passwords not easy to remember, they’re very insecure and easy to hack into. Don’t believe me? Take a second to google, “how to hack into a wireless network” for a good scare.

For one reason or another, you may want to change the settings on your comcast modem / router / cable gateway . Below is a short video detailing exactly how to perform this process from an Apple computer.
