[Techtalk] Wireless networking - OT

[Betty Johnson]

I am having a rather puzzling time with trying to set up a wireless 
network.

First they are all Windows machines and that is why I am putting OT in 
subject. Linux is not an option. One machine is XP Pro, the other 2 are 
XP Home.

This is the setup/scenario.

Wireless router attached by cable to Pro machine. Pro machine picks up 2 
IP addresses, one for wired link and one for wireless. No firewall set up 
for network yet. No internet connection yet. No WEP configured yet.

Both Home machines pick up IP address. All 3 machines can ping back and 
forth.

Pro machine can browse to all machines in My Network Places. Cannot browse 
from either Home machine. Installed Netbeui on both Home machines. 
Network now working as planned.

Go to set up WEP.

Router is showing other machines in area picking up IP address from 
router, so I powered off the router and reset.

Turned on the router. Set up WEP. Now machines not picking up IP address 
from router on wireless network. Change channel for SSID.

Now only 2 machines of 3 are picking up IP address from router and the 3rd 
is picking up from another wireless network in the neighbourhood. I keep 
telling it not to connect and it does. It even updated virus definitions 
and this place does not have Internet yet.

What should I do now to get this Lan working? Change SSID again? I am 
really tired of beating my head against a brick wall. Thanks to all 
suggestions.
