Aquiring Network Address problems

[jdublu]

i have a wireless network with a linksys wrt54g router. my base station is running xp home and so is my wireless Toshiba laptop and my daughters wireless Compaq laptop. i went to the linksys Wirless-G broadband router website (192.168.1.1) and set up WPA-TKIP Personal encryption and assigned it a 12 digit WPA Shared Key.
My daughters new Compaq laptop works fine with these settings but my Toshiba laptop, in the "Choose a Wireless Network" program box says "Aquiring network address". it shows IP address 0.0.0.0 : Subnet Mask 0.0.0.0 : Assigned by DHCP : IPv6 Enabled : Access Point : Networkmy network name) : Encryption Disabled (why disabled when set to WPA-TKIP?-Is this a problem?) and Signal Strength Excellent.
How can I get the Toshiba to get an IP Address and all the other settings to work in encryption?
I also found my neighbors wireless network name shown in the "Choose a wireless Network" dialog box so when my network is set to "Disabled" for encryption they can see everything we have on our pc's if they want to. NOT GOOD!!
Thanks,Jim

if you hit "refresh my wireless network list" does you own wireless network ssid appear?

Are they both at service pack 2? You need SP2 or THIS patch for SP1 to use WPA with XP home.

try assigning static IP address instead of automatic IP address with DHCP enabled.
