The 169.254.0.0/16 network has been proposed for use in automatic
configuration in the absence of a DHCP server. I am not aware if this is
an actual sanctioned use, but it apparently has become de-facto use by the
presence of implementations such as Microsoft Networking.

Ergo, the computer(s) having trouble are probably Windows machines, and
are having difficulty contacting the dhcp server.

I don't know.  I would look for lower-level troubleshooting tools for this
technology.. I have not played with wireless.
