I got a new 2013 Airport Extreme yesterday and have it acting as the DHCP and NAT server with the cable modem in bridge mode. Everything was working fine until I woke up this morning and there was no internet connection. The light was green and devices connected to wifi fine, but there was no actual internet connection (neither wifi nor wired) until I power-cycled the Extreme. Any idea what caused this? Here are my settings: Connect using: DHCP Wireless: Create a wireless network Router Mode: DHCP and NAT The modem is an SBG6580 in bridge mode.
