This is a problem getting an AirPort Extreme to connect with a BT Home Hub. The point is to use the HH as a modem only, and the AP to generate the wifi. I'm asking this for a friend, so there may be some delay in finding out any more information than is below. All the information I have is as follows: Both the BT Home Hub 5 and the Mac Air Port Extreme 802.11ac are new. The HH is connecting to the web fine. The light on the front is blue, and he can log on to its wifi. He wants to use the AP instead. This is not working. The light is flashing amber. The AP is connected to the HH with an Ethernet cable, WAN socket to red socket (which I think is the WAN socket on the HH). Running Airport Utility on an iMac, we set up a network on the AP. This can't connect to the HH, even though I've looked through several articles on forums (below) and set it up (I think!) correctly. Airport Utility reports the following problems: - PPPoE Server - Internet connection Both the AP and Internet indicators are orange in Airport Utility. AIRPORT EXTREME CONFIG (from AirPort Utility) ============================================= IP address: 0.0.0.1 - I presume this is because it's not connected, and not getting an IP address from the HH.
