Setting up a Broadband Network

[Guest]

Hey all I am trying to connect a second computer to a Motorola Surfboard
SB4200, which gives me blueyonda broadband. Both pcs are running XP. I have
a TRENDnet Internet Station rooter (TW100-S4W1CA). The Surfboard modem is
connected to my pc by a USB wire, and the rooter is connected by a network
cable (not sure of the technical name for the wire UTP RJ-45 network
cable??)...then the second computer I want to get online is connected to the
rooter by another network cable.

I truly have no idea what I am doing. Do i need another network cable, to
link from the rooter to my computer? even though it's connected independently
by the USB wire. Or do I need to configure a network on this system?

I would be truly gateful for any help getting this network sorted.
Thanks a lot.

Alex,

Here are a few websites with useful tutorials on setting up a home network:
http://www.cablesense.com/
http://www.homenethelp.com/
http://www.practicallynetworked.com/
http://www.wown.com/

The normal configuration, which most tutorials will cover, is to connect the
modem to the router, and the router to both computers. Since you have a USB
modem (gack), you have to connect the modem to one computer, and the first
computer to the second computer.

You CAN connect the two computers thru the Trendnet router, but not easily.
You'll need (as you suspected) two Ethernet cables - one each between the router
and each computer.

You'll have to setup ICS or a proxy server on the first computer, to provide
internet service to the second. Then, you'll only be able to use the router as
a hub.

To use the router as a hub, with an ICS server, you have to:
1) Disable DHCP on the router.
2) Connect the ICS server, and all ICS clients, as peers to the LAN side of the
router.
3) Change the LAN address of the router from 192.168.0.1 to something like
192.168.0.99 (gotta keep it on 192.168.0/24 subnet).
4) Setup the LAN interface on the ICS server as 192.168.0.1.
5) Setup any ICS clients to use DHCP for all settings (obtain IP address and
DNS servers automatically).
6) If you're going to do file sharing, either disable ICF on the ICS LAN
connection (not recommended for a wireless router), or open the following ports
in ICF for the LAN connection: TCP 139, 445; UDP 137, 138, 445.

Post back here with any more questions. It is simpler than it looks, but it's a
lot easier to set it up than to explain it.

Cheers,
Chuck
Paranoia comes from experience - and is not necessarily a bad thing.

Disconnect the USB cable. Use a network cable to connect the modem to the
Internet port on the TRENDnet router. Use network cables to connect each
computer to one of the TRENDnet router's local network ports.

An SB4200 has both a USB and an RJ45 port:
