Answer 1

Although it may ultimately be necessary to perform a Factory Default Reset on the AirPort Extreme and start over with a new configution, we can first try to see if things will work with the existing settings on the device.
Push the reset button (if present) on the cable modem
Power off the modem by pulling the power cable
Remove the internal battery from the modem (if easily accessible)
Power off the AirPort Extreme and every other device on the network....order is not important
Wait at least 20 minutes....longer is better
Re-install the battery in the modem if it was removed previously
Make sure that the Ethernet cable from the modem is connected to the WAN port (circle of dots icon) on the AirPort Extreme
Power up the modem and let it run 4-5 minutes buy itself
Power up the AirPort Extreme and let it run 4-5 minutes
Then power up each other network device one at a time about a minute apart
Check for a good Internet connection on the network with all devices
If still no luck, you will need to perfom a Factory Default Reset on the AirPort Extreme as follows:
Pull the power plug from the back of the AirPort Extreme
Hold in the reset button and keep holding it another 8-10 seconds while you simultaneously plug the power back in to the AirPort Extreme
Release the reset button and allow 25-30 seconds for the AirPort Extreme to restart to a slow, blinking amber light
Then open AirPort Utility end reconfigure the AirPort Express again.
