Got New Router | Confused by DSL Cable Instead of Ethernet

I bought a new router but it has a DSL input connection which my old one did not have a DSL input, but does not seem to have an ethernet input. Back looks like this:


Connecting from my Motorola cable modem gateway, it does not have a DSL output.

Using DSL Cable

However, I could fit the smaller DSL cable in the place I'd normally fit a the ethernat cable. It fitted in snugly with no forcing so I assumed it was meant to work with both DSL and Ethernet cables.

The internet does not work this way, but I don't know if it is just because I configured the new router wrong.

So I tried something else.

Using Ethernet cable.

I plugged an Ethernet cable into the cable modem gateway as I would have normally done with my old router. And then I just plugged the other end into the first ethernet output on the Modem. I plugged my computer into the second Ethernet output.

I got internet connection this way, but my PC had the real IP address like 77.86,75.11, rather than the 192.168.0.2 it would normally have got on the old router. Also I could not connect to the router now using the address 192.168.0.1, whereas when I used the DSL cable with the new router I could log into the router, but not get on the internet.

Which Cable Should I Be Using?

It looks like you bought a combo DSL modem & router. According to the User Guide for the SBG900, it has a router built-in and you just need a network switch.

That confuses me even more? What's a network switch?

I looked up a network switch and it doesn't seem to be something I need. Surely I just connect the Cable Modem Gateway to the new router, using the right cable, set up the router correctly and I should be done.

So I just need to know which cable to use. Anyone?

What is the make & model of your new router? According to page 4 of the manual (http://broadband.motorola.com/consumers/products/SBG900...) for your SBG900, you need a netswitch (or hub) for multiple wired connections.

Return the new router, it's not going to work. It's a combo DSL Modem/Wireless router and REQUIRES a DSL Internet connection. You need a wireless router WITHOUT a built-in DSL modem.
