Strange Airport Express Connectivity Issue

[bwhitta]

Experiencing an issue with my Airport Express. Airport Utility shows I have an active Internet connection, but two status errors for the Airport Express. As shown in the screenshot, the AE prompts that it does not have an internet connection and no DNS servers. My Macbook Pro connects to the AE over wifi and the connection works fine, but no iOS devices will connect to the network.

I've reset the AE numerous times and cycled my modem.

I think I experienced this last night. I could cat5 with my modem and confirm my internet was working but when I hooked to the Airport I didn't get anything.

I Called my ISP and they said they could see my Airport offline and something about a handshake between the modem and router.

They did something behind the scenes and it fixed it. Dunno?

This is usually attributed to the modem being in bridge mode and the Express being in bridge mode as well.

Is your AE in Bridge mode?
Does it obtain and IP address automatically (via DHCP) or manually?

It looks like it connects to your network using a correct IP address and subnet, but no DNS / Gateway seemed to be configured (thus manually configured)

Your MacBook might get its IP via DHCP, thuis getting the correct DNS and Gateway (Router)m but the AE is set to manual.

Check your Internet-settings akin the screenshot.
