Problem Connecting to existing Wireless LAN

Hi

I have setup a wireless 54G lan in my house with the linksys router, DSL modem and pc(win2K) upstairs.  I have a Win2k laptop with wireless 54G pcmcia card in it and downstairs another Win2K PC.  Up to now all was working perfectly well.......  Until I rebuilt the machine downstairs with WIN XP.  I am no expert on WIN XP but it seems to have detected my wireless lan card and configured it - the status says its enabled and signal strength is excellent.
However I cannot connect to the Internet or to any other PC in the house.
Ipconfig /all on the winXP machine reveals the following

I believed the WinXp setup should have picked up the router and obtained an IP address from it but that does not appear to be the case.  I even tried uninstalling the card and starting from scratch.  The funny thing is when I "View Available Wireless Networks" it picks up linksys1 which is my router
How can I get this machine to see the outside world ? What am I not doing ????

1.  Do you enable any encryption or security functions such as WEP?

2.  On your router, did you turn on MAC address filtering (this is probably a mute point, but just in case).

3.  Sometimes, just enable and disable the wireless card from Network properties will resolve the problem

Also post the ssid for the lan, and is WEP turned on?

this looks fine. How did you manage to set 192.168.1.103 for the laptop and the pci card?

Hi,

I think I've solved the problem - Originally I set up my network with 3 WIN 2K machines - I then changed one machine to Win XP and expected it to hook startight into the network (after configuration of course).   I then decided to think so I switched off the router and cable modem and PC's and switched them all on in sequence - Modem, Router and finally PC's and this seemed to have solved my problem - My Win XP machine now has an IP addr in the correct range and subnet.  

I still think the XP machine should have selected an IP addr from the router first time as I set it up to use DHCP from there but that's computers...  Problem solved anyway so thanks for all the input you made me think from scratch...
