Kings to you matheweis. The cables WERE reversed. I pulled that one off some time in the frantic process of resetting the Airport. How do I award you your points? This is my first question.

I've connected the Airport to the internet via DHCP served by the broadband modem. I've connected my two Macs, one wirelessly and one hard wire to the Airport. Airport is serving DHCP to the Macs. All lights are green but not getting web site response. 255.255.254.0 subnet mask. <br />
<br />
If I disconnect the Airport and go directly to the modem with hard wire the internet still won't connect until I reboot the modem and Mac at the same time. Then, I get a new IP address and the internet access.

All looks connected but no internet

Apple devices including Macs, iPhones, iPods and iPad support standard wired and wireless networking technologies, but they also utilize custom applications and some special techniques for networking with each other and with non-Apple devices. Apple manufacturers the AirPort line of wireless networking products, and has its own networking protocols, AppleTalk and AFP (Apple Filing Protocol).
