My iBook G4 can't seem to get a valid ip address from my router. Both the stock airport extreme card and built in wired Ethernet nic only manage to get a generic 169 range self assigned ip, which doesn't work. All of the other wireless and wired clients on the network don't have any DHCP issues though, meaning the iBook is at fault. I requested a DHCP refresh in the system settings, restarted the router, and reseated/cleaned the airport card, but nothing changed. I also manually filled out the TCP/IP settings pan, but despite the system preferences changing to say that the network is fine, it is not. I still have no connectivity. I should also add the iBook has worked fine with the router, a Netgear WNDR3300, for about a year now, so I don't think there any compatibility problems. Any ideas what the issue could be here, or how I could fix this?
