Connecting a Cable Modem to a DSl Wireless Router For Wireless connectivity

Hi everyone i have a bit of a problem.
Basically I used to be on DSL and now am on cable so I have a cable modem and a dsl wireless router.

Im wondering how I can get wireless conenctivity to the new with plugging the cable modem into the router.

I can connect via ethernet with ETH Port 1 connected to the cable modem from the DSL wireless router and ETH Port 2 connected to the laptop from the router.

But wireless does not seem to work

I dont know what to put as the ip address, default gateway etc.

Here is my Ipconfig -all info when connected via ethernet from port 2 of the dsl rotuer:

IP:77.103.149.48

Subnet:255.255.252.0

Gateway:77.103.148.1

DNS:192.168.0.1

upon copying this to my wireless TCP Ip setting it does not work.

I have a belkin router.


Thanks

you really want a cable router with NAT to get this to work in a safe way

It does depend on the router, however most won't allow you to change the assignment of the ports.

The ADSL routers have the modem built in and a bridge to carry traffic between the switch, the router and modem.

I'm suprised you can even connect to the internet plugging both the cable modem and the computer into the router.

What make/model of modem is it?
