Use DSL router on Cable Modem feed

Specs: XP, P4-3

Hi,

I just switched from DSL to Cable internet since my new place is too far for DSL. Can I still use the Westell 327w router on the cable modem feed?

I am thinking to daisy chain the Westell 327W to the cable modem with a cross over cable. Well, I am not sure if that would do the job since I can't find my cross over cable from the bags of cables I have.

1) I am not sure if the Westell can be daiy chained. It looks like so from one of the plug label in the back.

2) I am not sure if just a cross over cable is enough.

Any input would be appreciated.

Thank you in advance.

Ive never heard of a "DSL Router" unless your talking about a DSL modem/router combo. Basically the router doesn't know wether it connects thru cable or DSL -- It only knows about the TCP/IP traffic that is transported. In network talk a router is a "Layer 3" device while dsl and cable are Layer 1. So you should be able to use your Westell router on the cable connection.

Normally a router is connected to a modem using its WAN port which is separate from the LAN ports. Usually this rakes a normal cable not a crossover cable.

From the description the 327W is a DSL modem with router. The best you could probably use it is a hub. Unless your cable modem has DHCP you will not get NAT for the use with multiple computers. Get a regular router and avoid the hassle of trying to configure it.

Yes, the 327W is a DSL modem with router. The cable modem has DHCP. I used to do this with mini-hub (barebone router with no firewall & NAT) between a DSL modem and local network. Now, I misplaced the cable and not sure if cable modem work similiarly like the dsl modem (as far as ethernet concerns)and not sure if the 327W router can work with a cable modem.

I would have done the connection already if I found the crossover cable. I am trying to figure out if getting the cable would solve the problem.

Why the hassles? I have the router and even have the cable(just don't know where I put it). I had it work with a DSL modem before.. just not sure if it works with a cable modem.
