Cable Modems and routers

Hey network nerds, I need some help. Do any of you guys know of a cable modem that has multiple lan connections? Not looking for a Cable modem with a 4 port hub passive hub, but more like a Cable modem with an active switch.
Currently I am running a Scientific Atlanta Cable Modem(?) into a Belkin wireless router. My file server has (2) 3Com ethernet cards bridged into the router. I envision a Cable modem w/ multiple switched connections to connect a router w/ multiple switched connections. I know a bit about networking, but not enough to know what I am looking for. Any ideas guys?

None come to mind. Why do you want a switch versus a hub? You'll way overwhelm your bandwidth before you overwhel your network. A cable modem is a consumer device. It doesn't make sense from a manufacturing point of view to run a switch versus a hub.

Agreed.



Here's the manufacturers link from AVB's post.



What are you looking at trying to accomplish? Feel free to PM.

....except if you have a DNS server / NAT router in your network, my experience is that they won't work across a hub - have to have a switch.

Switches are dirt cheap....no reason not to have one. In terms of sheer products available, a quick check of a couple of my usual vendors show ethernet switches available at about 2:1 over hubs....

My $00.02 - B.B.S.
 
Right now it is just an abstract idea. The reason for a modem w/ an active switch is to ensure a robust network. I'd use 2 routers. 1 wireless router and one traditional router. The traditonal router would have a switch, connected to my file/app server that has 2 bridged ethernet cards. I run Gnutella on that server. It doesn't eat a lot of bandwidth, but there is a huge amount of network traffic.

The wireless router would be for 2 laptops and a workstation for basic surfing. I am also thinking of running a gameing network on the wireless network.

So as you can see, I am not pushing the limits as far as bandwidth goes, but there will be plenty of traffic.

Am I correct in that the switched modem divide network traffic and allow both networks to run more efficiently?

Well scratch the routers as it has a built in router. I'd use the wireless router as an acces point and disable the firewall/router services.
