Sharing internet connection with wireless router and two NIC's

[Guest]

XP Pro (all users)
One desktop computer, several laptops
Two NIC's in desktop
One Broadband connection

My Linksys wireless access point router will not allow MSN Messenger to work
correctly with video and voice, but when disconnected and my computer
connected directly to my broadband connection everything works normally.

With two NIC's installed in my desktop, is it possible to maintain my direct
broadband connection while somehow using the other NIC to provide a
connection to my wireless router so that I can still use its wireless
features to share a connection to the internet via several laptops that my
family uses for work?

Yes, if you enable ICS, that should work for other computers.

Yes. Here's how:

1. Enable Internet Connection Sharing on the desktop's broadband
connection.

2. Disable the router's built-in DHCP server.

3. Connect the desktop's LAN NIC to one of the router's LAN ports.

4. Don't connect anything to the router's WAN port.

Thank you Steve,

That solution worked well except:

I had to reconnect the router to my primary NIC to control it and switch off
the DHCP.
Then reboot the Cable modem to reacquire a valid IP address.
Is this the only way to control the router?

The last problem is that although the wireless router is broadcasting well
and is detected by the laptops, I cannot connect to it wirelessly through any
of our laptops because the laptops cannot acquire a valid IP address -
because the DHCP is disabled?

How do I manually configure the correct IP address onto my laptops?

The spare NIC that is controlling the wireless router is set to 192.168.01

I cannot find a way to manually configure the laptop.

I really appreciate your time and I look forward to your response.

Miles.

Why do I need to disable the DHCP server?

Yes. Here's how:

1. Enable Internet Connection Sharing on the desktop's broadband
connection.

2. Disable the router's built-in DHCP server.

3. Connect the desktop's LAN NIC to one of the router's LAN ports.

4. Don't connect anything to the router's WAN port.

You're welcome, Miles. It's usually necessary to reboot a cable modem
after changing the device (computer or router) that's connected to it.

We want the ICS computer to act as the DHCP server for the other
computers. I've seen cases where a router doesn't pass DHCP packets
through when connected in the way that you're doing. If that's the
problem, the solution is to manually configure the laptops. On each
one, right-click the network connection, click Properties | Internet
Protocol (TCP/IP) | Properties, and assign these values:

IP Address: 192.168.0.x (1<x<254)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1 or your ISP's DNS server
