Internet Connection Sharing Doesn't Work

[Robert MacNab]

I have a dedicated NIC that's connected to a Netgear wireless router
and I use ICS to connect my laptop to the Internet through the desktop
computer at home. It's running Vista Business. The laptop is running
XP.

The desktop is supposed to be a DHCP server and assign in IP address
to the laptop but it doesn't. It worked okay when the desktop ran XP.
It assigned IP addresses like 192.168.1.1. Now I get random addresses
that look like real internet addresses but the laptop can't connect.
Can anybody tell me if I'm doing something wrong?

Why are you using ICS, when you could connect the laptop directly to the
router?

I ran with one NIC and the router between the desktop and the cable
modem for a while. I found that I couldn't get more than 3 or 4
Mb/sec through the router. I tried a D-link and then this Netgear
with similar results. When I used encryption on the Wifi link it was
even slower. The router slowed down the desktop access to the Intenet
like the laptop. So I added a second NIC. One NIC connects to the
modem and gives me ~6Mb/s for the desktop and the second NIC does
Internet Connection Sharing for the wireless router. The laptop gets
slowed down but the desktop doesn't.

I don't understand it. The router makers advertize 54Mb/s and even
108Mb/s and I can't even get a cable modem to run at full speed.
