Please help with specific ICS configuration question...

[Guest]

I have been trying to set up a home network with dial up interface to the
internet, using ICS. I have run the network wizard several times, but cannot
get connection sharing to work.
Here is the configuration: two desktops connected via a router, plus a
wireless router connetced to the main router, with a wirelass laptop on the
other end. All run Win XP. I suspect that what is happening is that any or
all of the routers, plus XP itself, are trying to set dynamic IP addresses,
but I do recall seeing somewhere that the ICS host machine MUST be
192.168.0.1. So likely once the wizard thinks everything is set up, one of
the components shuffles the IP addresses and messes things up. In particular,
I think the DLink wirelss router also wants to be 192.168.0.1. The wizard
never offers to disable DHCP, but I suspect I should be assigning static
addresses to all components of the network. The documentation doesn't provide
any advice on how to do this, and I am nervous to start without some
guidance, so I need help from this expert community.
I would appreciate any SPECIFIC advice anyone can give, here or offline to
(e-mail address removed).
Thanks in advance for your help!

Yes, the host computer's LAN connection is 192.168.0.1. The other
computers' LAN connections must have compatible addresses in the
192.168.0.x range, either assigned by the host computer or manually
configured.

You didn't say how the routers are connected to your network or why
you have two of them. For this setup to work, use the routers as
network switches only, bypassing their routing capabilities. For each
router:

1. Disable its built-in DHCP server.

2. Assign a static IP address to the LAN interface that's different
than the host computer's address of 192.168.0.1.

3. Connect all wired computers to the router's LAN ports. Don't
connect anything to its WAN port.

to every machine in my configuration?

Thanks for the clarification

PS, the reason for two routers is that I could not make the wireless router
serve both wired and wireless at the same time. This may be because DHCP was
enabled, though.

A home broadband router has two network interfaces: Internet and LAN.
Assign a static IP address to the router's LAN interface.

You can configure the computers to obtain an IP address automatically,
or you can assign static IP addresses to the computers. For static,
make all these settings:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1 or your ISP's DNS server

If possible, use only the wireless router.
