ip-169.xxx.xxx.xxx

HP laptop WinXP links to router via CAT5 or WIFI, but does not
receive an ip from the router (dynamic ip). Link lights are
on. Several other systems, (xp and 2k and 98se) have
connectivity.
Yes, have checked cable, switch port, client and tcp/ip for
both links. Wifi can receive a signal from the router and it
can see adjoining offices in the wifi list.
Setting fixed ip is no-joy.
With and without Zonealarm.
I would suspect the adapter but CAT5 and WIFI ??????
Your assistance is GREATLY appreciated!

Are you saying you are trying to set a fixed IP from a router? If so
the router must be setup to work with those. Try going dynamic on the
laptop first then switch to fixed. There are a ton of settings and the
laptop will have to be restarted after alot of them. If another pc is
working and getting a number just fine, as you say they are, then
restart the laptop in an area that you know has a good signal. If it
still doesn't work there is a ton of trial and error settings to go
thru, do a right click on the icon near the clock and tell Windows to
find the wireless network, go into network neighborhood and set
everything to the defaults, that would be dynamic IP address. Go into
IE and go to tools, internet options, connections, lan settings, put a
check in the automatically detect settings. After everything is
working you can uncheck this box for a faster connection.

Thanks for the input George.
I should have been clearer about my steps.
I can see the 169.xxx ip in "ipconfig".
This happens with Cat5 or with wifi.
I am using dynamic ip not fixed!
Lets rule out wifi for now. I have it turned off
using cat5 only. Again the link lights are on for the
sw port and on the laptop.
The other systems run ok both here and at the office.
I see the same thing in both locations.
In Lan settings "auto detect" is set.

hosts, who can't obtain an IP address from a DHCP server.
It is called the "link local" block. It is allocated for communication
between hosts on a single link. Hosts obtain these addresses by auto-
configuration, such as when a DHCP server may not be found.

I hope this helps you...

*****************************************
I understand about the "link local block".
It would seem obvious that the client is not seeing
the dhcp server, in this case the router.
Since I started this thread, I suspected a winsock
problem so I ran a small routine called Winsockfix.exe.
It re-establish the links and all is well.
Thanks for all input!
