I'm having problems configuring my 17" PB AirPort Extreme with AirPort Extreme base station and Alcatel SpeedTouch Pro (Firewall, with 4-port hub) ADSL router.
My base station now lists TWICE in the admin program. I tried resetting (1 sec) and resetting to defaults (5 sec), still listing twice. I can't config either of them in AirPort admin utility! I'm still on 5.01 firmware and can't connect to config menu in order to upgrade to 5.03. AirPort software is 3.0 from AirPort base station CD.
What next?
Which port of the AirPort base station do I connect with my Alcatel router (WAN or LAN)?
DHPC or manual? (Alcatel is my DHCP server for the LAN)
Disable IP address sharing on AirPort extreme base station? Disable NAT/PAT (Alcatel does this for my ADSL line)?
Setup Guide didn't help me much. So please, all you network gurus out there.
