I'm a total newbie when it comes to these things. I thought setup would be as easy as connecting the Ethernet cable from my NVS589 gateway to my Airport Extreme, then plug in the power cord into the AE and set up the Wi-Fi Network on my Macbook. And I was able to do all that, actually, but it didn't connect me to the Internet--the AE just keeps flashing amber and I get a message saying to power cycle the modem and, failing that, to contact my ISP (which I did, and they said they couldn't help me). Do I have to make configurations on 220.127.116.11? I have the U-verse bundle which includes a landline phone and TV, if that makes a difference. Please help!
