Let's draw this out in a diagram:
Laptop---(wireless)--------Lucent WAP===(ethernet)==Linksys router
169.254.93.100/16 (right) 169.254.x.x/16 (left)
192.168.1.150/24 (right) 192.168.1.1/24 (left)
24.x.x.x (right)
Does this make sense? I had to go back and look over your comments again
to put this together. It sounds/looks like the Lucent gets its IP via
DHCP from the Linksys, and your laptop gets its IP via DHCP from the
Lucent WAP. Apparently, however, this is not happening. Instead, you
have to hard-code your IP and DNS entries in your laptop to make it
work. Is this correct?
Do you know the inside ("left" in the diagram) IP address of your Lucent
WAP? Given that your subnet is 255.255.0.0 (16 bits, thus my /16
notation), the IP should follow the pattern I show in the diagram,
169.254.x.x.
It sounds like DHCP is not working in the Lucent. This would explain why
you had to hard-code your IP address, subnet mask, and DNS entries in
WinXP. If you can get it working, you should be ok. In truth, it doesn't
make any sense to me that WinXP shows the 169.254.x.x address, because
that address space is only supposed to be used for APIPA (a different
kind of automatic IP addressing), not DHCP.
If my diagram is incorrect, then please correct it (including IP
addresses) so we have a better understanding of how things are laid out.
