Hi Guys, So the setup in my house goes like this Motorola Surfboard Modem (Comcast) is connected with a blue LAN cable to the Linksys Vonage Router and then from there a grey Ethernet cable is connected to the Airport Extreme. For some reason Vonage works (so therefore it is getting internet from the modem) but the Airport extreme is blinking amber and when I go in Network Utility it says the Airport does not have a valid IP address? But I can see the Aiport network on my iMac. Also when I try to plug the Ethernet cable in to my computer it also says it doesn't have a valid IP address. Any help resolving the issue would be awesome.
