Aha - this is a bit of a specialist subject for me....
If the N110 isn't getting a DHCP address when connected to the specific wifi, have you tried....
- Changing the authentication method the wifi uses. There's some NIC incompatibilities out there with the way encrypted authentication over wifi works. If you (temporarily) remove wifi authentication from the AP, does the N110 manage to connect and get an IP address?
- Updating the firmware on the Netgear? there's regular updates on the support site, and you might find that the code relating to the authentication on wifi in the Netgear has changed.
I would state that after 2 solid (and boring) years of designing Nortel's global DHCP rollout to a quarter of a million nodes, that if a client's not performing DHCP then there's likely to be something more significantly wrong with the link than purely that.
