Can't figure it out

[wtbarp]

I can't connect My Host computer to a wireless network.

I'm trying to network two machines, both running XPHome, but
when I try to run the network setup wizard on the Host
computer, and choose "This computer connects directly to the
internet. The other computers on my network connect to the
internet through this computer", I get a message that says:
"Cannot complete the network setup wizard. Other computers cannot connect to the internet through this computer.

In addition to its internet connection this computer must have a connection to your network"

The network is configured as follows: An external cable modem
(Terayon TJ 715) to a Linksys wtr54g wireless router, to the
onboard ethernet port on the host computer and a Linksys 54g
wireless pci card in the remote computer.

Both machines show a wireless network connection in network
connections in control panel, and both machines have a connection to the internet through the cable modem, but nothing
shows up in My Computer or My Network places. I have set
1 logical drive on the remote computer, and all drives and
printers on the host computer to be shared. (There are 2 printers; both connected to the the usb on the host computer).

Also when I right click on the wireless nework connection in the
remote computer, I get the option "View available wireless
networks" wich takes me to a "Connect to wireless network" box which showes a wireless network called "linksys",
but on the host computer this option is not available.

Any help would be GREATLY APPRECIATED.

Thanks, Rod
