Win2003 Server SP2, 150 clients,
problem is happening randomly to
around 25 wireless lab laptops.
what is odd is that some laptops
are working fine and then maybe
2 will automatically lose DHCP
connection (static does not seem to
be a solution either always).
3 different AP's (2 brands 3COM
and Netgear),
4 different brands of laptop have
done this with different NICS,
the wireless connection
itself is excellent or very good.
These laptops were working great for
~2 months and then started
dropping slowly like flies.
Tried: Registry fixes, WZC, MS TS
testing of DHCP (traces show that the
DHCP is going through its paces),
googling and testing. Does not
seem to be a specific fix to this
but a lot of people seem to
find the problem.
Currently, I am on a Lenovo
3000 N100 and ipconfig /release
and ipconfig /renew will hang
with No operation can be performed on Local Area Connection
1 out of 3 latops at this location
is working and a desktop right
next to it works great also (so
all are working through the same
local unmanaged switch and
then through the managed
switch. IP comes back as
169.x and logging in to the
wireless as domain admin
works real fast but then
check and 169.x and yet
the wireless itself is running
strong.
My job is hanging on this fix
so I am anxious for anything
anybody has seen ASAP.

Is there enough address on your DHCP server? Is NAT turned off on your AP? Is DHCP turned off on you AP?

Assuming you get you run DHCP on your router, try updating the firmware, reset to factory defaults and set up the router again.
