Internet Connection Sharing

[satan]

OK here is my problem:

I am trying to enable Internet Connection Sharing on one of my computers. The Internet is through a wireless LAN card, and the client connects through a wired network card. When I try to enable ICS on the wireless connection, I get the message:

"Internet Connection Sharing cannot be enabled.
A LAN connection is already configured with the IP address that is required for automatic IP addressing."

This has confused me because I have changed the IP addess of my router to 192.168.0.20, so there is nothing on the network using 192.168.0.1, which I think ICS requires.

I cannot connect the client to the router because it is too far away to use a wire, and I can't add a wireless network card because the computer only has ISA slots, and there are no USB ports. The only other option would be to use a wireless ethernet bridge but that would be too expensive.

I have read somewhere that the problem may be related to me having 2 DHCP servers on the same subnet, the router and the ICS machine.

Can anyone help me here?

Thanks in advance.

Try turning DHCP off on the router and instead manually assign an IP address to your wired PC.
