With a cable internet provider (e.g., Comcast), two pieces of equipment are required to connect to the internet and the WiFi network in your home:
- A modem connects your home to the Internet Service Provider's (e.g., Comcast's) network
- A router connects your wired and wireless devices to your modem
The wireless gateway (like Comcast's XFINITY) is a common way cable Internet Service Providers (ISPs) combine a modem and router into one piece of equipment.
To use your own router (e.g., a Router Limits enabled router) you will have to enable the Bridge Mode feature on the wireless gateway, which turns off its routing capabilities while leaving the modem capabilities on. Then you can connect the Router Limits enabled router to Port 1 on the back of the gateway modem.
Follow this link for instructions on how to enable Bridge Mode on a Comcast modem gateway:
If you are using a cable modem other than Comcast, you should be able to find instructions for it on the internet.
If you are unable to enable Bridge Mode on your modem, or find instructions on how to do it, please contact your ISP and have them assist you.
