I have a prexisting network with 3 computers connected through a hub. I want to add a broadband router to the existing hub. How do I go about doing that?

Is it a cisco router?connect the router to the network(hub) and the internet connection turn router on.kidding.You should get the router software with it load the software it should ask you for the subnetmask you need choose 256.128.256.256 class c then select the routers ip address continue loading software then ping the router if you can ping it then try the internet out. Pretty much that simple ps check the class c address?If you need anything more let me know. I could be wrong

Connect using any ordinary port on the router to any ordinary port on the hub. You may need a cross-over cable for this. Some hubs have special cascade ports or switches that remove the need for a cross-over cable.

The easy way to do this is to plug the Broard Band Modem into the CABLE DSL router Now take a standerd Cat 5 cable from the uplink port of your hub into the CABLE DSL router's #1 port .. set all the internal PC's to auto .. I just dont understand why you would want to do it this way when most Cable Dsl Routers come with 4 or 5 ports on them anyway

Just get a Linksys router with built-in 4 port switch. Probably down to $79 by now. Connect routes WAN port to the modem and the 3PCs into any of the numbered LAN ports and save the hub for when you get your 5th PC. Make all PC's dhcp clients and your set.
