[DM-MUG] Can't get rid of "self-assigned IP address"

[CW Smith]

I did the same AirPort update Thursday, when I was first trying to get this
iBook wired into the router.

Just for comparison, my own iBook (the one that's working just fine) has
AirPort and Ethernet connections.  Via AirPort, DHCP assigns 10.0.1.11.  I'm
able to disconnect from the Ethernet cable and walk around the house with no
problem.  Via Ethernet, DHCP assigns 10.0.1.2.  Again, mine accepts its DHCP
assignments just fine, so I don't think the problem is the router.

My wife's iBook (the problem child) also has AirPort and Ethernet
connections.  Via AirPort, DHCP assigns 10.0.1.3.  She is able to connect
via AirPort and take her machine almost anywhere in the house, but signal is
weak and erratic in her office.  So I decided to run an Ethernet cable up to
her office from mine (well under the 300' maximum).  Via Ethernet, DHCP will
assign a 10.0.1.x address for a few seconds, then it is overridden with this
169.254.x.x "self-assigned" address (I know I never assigned it).

I have tried creating new "network locations," and all looks good until the
169 address butts back in (a new 169.254.x.x address is generated every time
I create a new location).

I have tried setting up DHCP with a manual address -- but then I lose the
router.

I've tried repairing permissions, resetting PRAM, resetting NVRAM, trashing
network preferences, all to no avail.

I have brought my own iBook into my wife's office and connected to her
switch.  No strange addresses, so I know the cables are good.

Needless to say, I am getting very frustrated.  I've been banging my head
against this for three days.  WHAT AM I MISSING HERE?

Peace,
Curt
