Airport Extreme (N) can't connect to DSL via SBC SpeedStream 5100

It's called 'Hardware Provisioning'. Call your ISP and ask them if that is what they do. If they do, ask them to release the old hardware address because you are connecting a new router.

If it is not a hardware provisioning issue, try powering down your DSL modem and base station, turn them off or unplug them; whatever is appropriate. Then first power up the DSL modem and then power up the base station.

Now try configuring the base station.

I have the same setup with no problems connecting. Set the AE up via ppoe, put your isp info in and it should connect. I also set my wired comp to the AE to manual in the network setting on the comp and assigned an ip of 192.168.1.3.I use that number to port forward. You can use anything from 2-200. The AE itself uses 192.168.1.1 or 10.0.1.1. I am assuming you are using the default 10.0.1.1 which is the same thing and can be changed within the AE. The wireless just uses WPA and can gain internet access by putting the PW that was given to my network. There is nothing else that needs to be set for any wireless computers on your network.

If you have PPPoE DSL, I suggest that you configure the SpeedStream 5100 in bridge mode and then configure the AEBSn router to handle the PPPoE login.

Setting the SpeedStream 5100 in bridge mode and then configuring a router to handle PPPoE is a known solution for certain Mac iChat video connection problems.

For setting the SpeedStream 5100 to bridge mode, cable connect your Mac computer to the Ethernet port on the 5100, set your Location to DHCP Ethernet and follow the instructions below, which may not appear precisely word for word:

1. In your Web browser browse to »192.168.0.1 This address will be located on a yellow sticker on the bottom of your modem.

2. The first screen will ask you for your Modem Access Code. This also will be located on the same yellow sticker.

3. Select Advanced from the blue buttons on the left.

4. Click the PPP locations button.

5. The modem may ask your for the Modem Access Code again. If so type it in again and click continue.

6. Select the radio button labeled, "Bridged Mode (PPPoE is not used)"

7. Click Save Changes.

8. A "PPP Location Warning" page will come up. Click "Change PPP Location."

9. A "Restart Needed" page will come up. Click "Restart"

After you have done this, simply configure the AEBSn to handle your PPPoE login, which will include your login name and password. AirPort Utility>Base Station menu>Manual Setup>Internet>Internet Connection>Connect Using: PPPoE.

The problem is not with Apple, it's with configuring the SpeedStream modem for bridge mode. If there's not a yellow sticker, is there a IP address starting with 192.168 somewhere on the modem?

I would call AT&T and ask for help in putting the modem in bridge mode if you can't figure it out yourself.

The problem is not with Apple, it's with configuring

You're right, the problem wasn't with Apple, the problem was with my new Mac Book which couldn't install the new Airport Utility. I ended up installing this utility on my G4 tower and ran it from there to configure the Airport Extreme (with Apple support holding my hand). I couldn't configure anything without this utility, and it simply would not get installed on the Mac Book. Go figure.

I'm up and running. Thank you for your help. Now I have to take the Mac Book and get the super drive diagnosed.
