The Ethernet cable may not be connected properly, AirPort Extreme may be out of
range of an AirPort network, or there may be a problem with your Internet service
provider. If you are connected to the Internet with a DSL or cable modem, the modem
may have lost its connection to the network or the Internet. Even if the modem seems
to be working properly, try disconnecting the modem from its power supply, waiting a
few seconds, and then reconnecting it. Make sure AirPort Extreme is connected directly
to the modem via Ethernet before reconnecting power to the modem.
