...it won't connect to home wifi while my old WhiteBook is. I have cable internet and a Linksys wifi router. Both Macs are running Snow Leopard. Whitebook connects just fine. uMB finds network, but Airport icon in menu bar has an exclamation point and states "Self-Assigned IP address". How do I work around this? I'll have my old one for another month or so and would like them to both be able connect to the network. Mroogle results didn't find anything conclusive. Thanks all.
