Splitting DSL with router

[Jordanl77]

Hey, I'm very new at the whole router/hub thing and i was wondering if you guys could help me out. I just purchased a SMC Barricade (SMC7004VBR) and it seems to be working with one of my computers but not the other.

System A:
Windows 98SE
SMC 1121TX-50

System B:
Windows XP SP1
Marvell® Gigabit PCI LAN controller and Southbridge Integrated NVIDIA® 10/100 Mb LAN

The setup:
DSL Modem cord to router WAN
System A via SMC 1121TX-50 to Slot 2 on SMC Barricade
System B via NVIDIA® 10/100 Mb LAN to Slot 1 on SMC Barricade

The problem:
I installed the software for the SMC Barricade on System A first, it seemed to have worked. I was able to surf the internet and check mail just as usual. I then installed it on System B and got the message that there was an IP mismatch. That's the problem, i'm basically just trying to configure it so I can use the internet on both computers.

I was also wondering if I should be hooking System B though the LAN connection. Here's a little post of what either modems do from the manufactuares site: "Marvell® Gigabit PCI LAN controller and Southbridge Integrated NVIDIA® 10/100 Mb LAN controllers let users access broadband via 10/100 Mb LAN port and share the Internet connection with network neighborhood via the Gigabit LAN port."

Thanks for your time, I hope some of you can help me with this, you all seem quite knowledgable with this stuff.

Any/all computers on the LAN side, should be plugged into one of the LAN ports of your router. Most routers have a built in 4 port 10/100 switch. Most of those ports are standard ports, however some routers will have one that's specifically labeled for "uplink", and may just be a crossover port.

For default setups, make sure your TCP/IP is set to obtain automatically on each workstation. Make sure, by default, that gateway and DNS is left blank, and on Win9X, have WINS disabled.

I am just really saying the same as YeOldeStonecat here but in anther way I guess, hope it helps.

DSL or CABLE via a Network Router.

the cable/dsl modem into the Uplinks port or the router. it will be marked Uplink. if it is not the uplink port is port number 1. most router have a cross-over connector port, or a port that can change from a Cross-Over to Stright-through automatically. that is more info then you need to know there, but it just really breaks down to you don't need a cross-over cable. then the workstations go into the other ports on the router.

this next step is for DSL only, set up your router to logon to you IPS for you. if you look in your router book it should tell you the IP to type in and how to set up the router password and what not.

now that you have that done tell all computers on the network thay are on a net work that has internet.
