thinkpad / desktop lan problem need help.

[alidabiri]

Hi folks,
i'm still having problem with home network. i've tried all the suggestions. including patches regfix, winsockxpfix, and letest updates. it started out with ip addresses changing. then i got a yellow triangle with ! i applied all the patches, no luck. here's the scenario: ibm think pad has a wireless lan which i disabled. the desktop intel p4 asus mobo has

marvel yukon 88e 8001/8003/8010I on the mobo
when i click property it has:
client for ms networks
file and printer sharing
QoS packet scheduler
TCP/IP (with DHCP enabled and automatic IP and DNS)

the lap top ibm think pad has:
wireless 11a/b/g mini pci adapter
1394 net adapter
intel pro/1000 MT Mobile connection
xircom realport2 ethernet 1/100 (i added this one)
when i click properties it has:
client for ms networks
service advertising protocol
file and printer sharing
QoS packet scheduler
NWLink netBIOS
NWLink IPX/SPX/netBIOS compatible protocol
TCP/IP (with DHCP enabled and automatic IP and DSN)

i have tried just about everything. updates, patches, reboot, and all.

any suggestions on what i can do next to get these 2 pc's to talk?
the network icon shows the ntework is connected, but both send packets, but not receive any. the ip address with ipconfig on the desktop is:
169.254.146.59
255.255.0.0
and for the laptop:
169.254.83.48
255.255.0.0
what determines which ip number be assigned to a computer? and why does it change when a computer is chenged on the lan?

You'll need a wireless router / access point.

The IP you're getting for wireless adapter is an internal DHCP address because it can't connect to a DHCP server.

and the internet connection works right
or are you using crossover cables to machines
are you using a router
if the wireless is disabled forget the access point right
somewhere in settings untick Enable IEEE 802.1x authentication for this network
