Peer-To-Peer Netwoking - Can't Share Internet Connection

I have two machines (desktop and laptop) running XP Home
Edition. They are networked with Linksys wireless cards.

The desktop has a broadband internet connection. Can't
access the internet from the laptop, The cable modem
connection is set up to share the connection but the
laptop can't see it.

The rest of the networking works fine (printer and file
sharing). Seems as if the desktop is not working as a DHCP
server as it should. BYW, I have disabled the firewall
software on both machines to eliminate that as a problem.

Enable Internet Connection Sharing on the desktop's broadband
connection. Configure the laptop as an ICS client. Details here:

Windows XP Internet Connection Sharing
http://www.practicallynetworked.com/sharing/xp_ics

Don't manually change the desktop's LAN IP address -- that can disable
its DHCP server.

If there's still a problem, these tests should help you find it:

1. On the desktop, right click the local area network connection and
click Status | Support | Details. It should show:

IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Default Gateway: none
DNS Server = none

2. On the laptop, right click the local area network connection and
click Status | Support | Details. It should show:

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

3. If #1 and #2 are right, open a command prompt window on the laptop
and enter these lines. Each one should get four replies:

ping 192.168.0.1
ping 66.102.7.99
ping www.google.com

4. If #1-#3 are right, enter these addresses in Internet Explorer.
They should both take you to the Google web page:

http://66.102.7.99
http://www.google.com

I understand where you are going with this. I'm wondering
if the sequence of actually installing my wireless cards
and enabling ICS on the deskyop is my problem. Let me
elaborate.

Intalled the wireless cards on both machines and was able
to connect to network "X" which I defined on the desktop
which has the broadband connection.

After the successfule connections the IP addresses assigned
(NOT by me but "automatically") were in the 169.xxx.xx.x
range.

After enabling ICS on the desktop, the address of the
network card on the desktop DID change to 192.168.0.x
as you indicated it would BUT the address on the wirelsss
card on the laptop was/is still in the 169.xxx.xx.x range.

The result is NO internet connnection and worse, no
network connection between the desktop and laptop anymore.

So I am stopped dead at Step 2. Would you suggest that I
uninstall both network cards and start over?

Maybe I need to install on the desktop and enable ICS
before installing the network card in the laptop?

Steve, thanks for your help. I solved this my retracing my
steps. The trick was to set up the desktop completely with
ICS and then install the laptop card. DHCP then supplied a
workable ip address for the laptop adapter. I was then
able to access the internet, share and swap files,print to
the desktop printer.

The only glich left is my Zonelabs firewall on the desktop
is blocking my laptop even though I have identified it as
trusted. Without the firewall active, everything else
works.
