Hi All, I recently purchased an Apple Airport Extreme to connect to my AT&T U-verse residential gateway (Model NVG589). I am having some trouble with the set up. I can access the internet through the Airport Extreme's network on Apple devices (macbook pro and iPhone). However, I can't seem to connect other devices such as my smart TV or PS4. I checked the airport utility and it doesn't seem like the Airport Extreme is pulling over any information from my residential gateway (IP address, DNS Servers, Router Address, etc.). My residential gateway is in passthrough mode (I followed instructions I found on several different sites), so I don't know what the problem is. Any thoughts?
