Can connect with ethernet direct to modem. Did hard TC reset and went through airport utility. Green light is on, but can't connect. Get this message from Airport utility: "self assigned IP address" can't connect.
3 yr old TC worked fine for internet until power in house went rapidly off and on. No ISP issue: can connect with ethernet from modem. Did a hard TC reset. Went through the Airport utility steps and got message that network successfully set up. Green light is on. Airport shows the network in toolbar, but no connection. Now Airport utility says there is a LAN problem--because of the self-assigned IP address?
