Trying to connect to the internet via cable modem with a static IP.  Have tried to enter DNS adresses manually as it prompts DNS addresses input, but still not able to connect.  Any suggestions?

    Make sure that you power off the cable modem completely by pulling the power cable from the back of the device or the wall AC socket.


    Pull the battery from the modem if it is easily accessible


    Hard Reset the AirPort Extreme by holding in the reset button for 9-10 seconds and then releasing. Allow a minute to restart


    Power off the entire network....all devices


    Wait at least 30 minutes.  Some ISPs take even longer for the equipment back at the cable company to reset and issue a new fresh IP address for the modem


    After the wait period, reinstall the battery in the modem it was previously pulled


    Power up the modem and let it run for at least 5 minutes by itself. 10 is better.


    Make sure that the Ethernet cable from the modem is connected to the WAN "O" port on the AirPort Extreme


    Power up the AirPort Extreme and let it run 2-3 minutes


    Power up your computer and reconfigure the AirPort Extreme


    Check for proper operation


    Power up other network devices one at a time about a minute apart

    Just to be sure I understand. Are you saying that your ISP is providing you with static Public IP address and you want to configure your AirPort so that it gets this address assigned to it?
