If you can’t connect to your WiFi make sure that your LED lights are blinking green. Locate the Gigabit WAN port; it is the port directly above the power cord connection on the back of the device. If the light is orange, you will need to check the modem.
Check if your WiFi connection is turned on. Check if your password is typed in correctly.
Power down the modem, the Airport Extreme Base Station (AEBS), and the computer(s); wait at least 10-15 minutes. Power-up the modem; wait at least 10-15 minutes. Power-up (plug into power) the AEBS; wait at least 10-15 minutes. Power-up the computer; it should now have Internet access.
First, unplug the Extreme. Then using a paperclip or similar object, depress the reset button, and plug the Extreme back into power. Keep the reset button depressed until the status light on the Extreme starts flashing rapidly; then release the reset button.
If encryption on the network has been enabled, verify that the router has been set up properly. Check the documentation that came with the product and ensure that the you are using the correct password and settings. If you are using a network secured by access control, verify that the MAC address is registered with the network administrator. Call the network administrator for further help with access.
When the Internet Service Provider (ISP) is down, you won’t be able to connect to the Internet. To verify that the problem is with the ISP and not with the AirPort Extreme, use a web browser on another computer that is directly connected to the Ethernet. If you can’t connect to the Internet with the other browser, restart your modem. If you still cannot connect, then the problem probably is with the ISP. If this is the case, you can either consult your ISP or wait for the service to return.
