SOURCE: CAN A 2WIRE DSL ROUTER WORK WITH A CABLE INTERNET CONEECTION

The 2wire dsl modem/router cannot be use with a another cable modem , since this 2wire device is also a modem/router and its made for the DSL conenction that's why it wont work with Cox cable, the best thing that you can do is to ask Cox to give a wireless modem/router like this 2wire so you can still use the wireless connection of your computer..

Hope that helps..........

No. A router has 2 main interface types WAN (for the internet connection side, and LAN (for the home network side) the 'LAN' side often has up to 4 ports and wireless connectivity for the home network.

The most common routers available at electronics retail use a CAT-5 connection for the WAN ports and the LAN ports. Your DSL modem/router uses a phone line input for it's WAN port, which uses a signal type that is incompatible with the cable modem output.

If COX doesn't offer a router with the cable modem package, you can go and purchase and common brand of home networking router, and attach it to the output of the cable modem.

Its almost impossible to connect a 2wire DSL router with a Cable modem. They dont go hand in hand.
Although you can connect the outgoing ethernet wire from the modem in the last ethernet plug on the back of the router and then have the ethernet connections coming from the router. But not wireless. and if you find a way, contact me at [email protected]
