Buy a modem. The router port is RJ45 because it is expecting an Ethernet connection from a modem. The MODEM will have an RJ11 input. RJ11 is the normal telephone connection. If you plug the RJ11 plug in from the telephone line into the router it will not work. Routers with built in Modems do have an RJ11 inputs.

Hi, I think was not able to explain it correctly Let me explain it again:

1. I have Linksys WGA160 N ADSL GATEWAY ROUTER Which has an internet input port which DSL.

2. Now I have changed my service Provider who provides RJ45 Cable Internet.

Can I use my existing ROUTER with This ISP where the input is on RJ45

Hope this will give you a better clarity.

You should be able to use that router with your new ISP. I would recommend resetting it to factory defaults before connecting it.

Typical setup for ADSL includes a modem. The telephone line (RJ-11) runs from the wall outlet to the input on the highspeed modem. The output from the highspeed modem is normally an RJ-45 which you would connect to the WAN port of your router.
