After factory reset, can't set up Airport Extreme!

Hello all!

American living in germany here. I am using a PowerBook G4 running OS 10.4.11

I am using an Airport Extreme Station with a Siemens Router. I couldn't get my iphone to work wirelessly via Airport, so I decided to do a factory reset. Now after having done that, my Airport Setup Assistant recognizes my Airport but after clicking continue to proceed, I always get the message that it is unable to find the base station.

I should add that my internet stopped working about two weeks ago. I thought it might be my system software so I reinstalled that on my Mac. Turns out it was my ADSL box so my phone company sent me a new one. I did get my Airport to work with my old settings and the new box....but after this factory reset, my computer can't communicate with it.

Help please....I need to be wireless again! Now I am on the internet via an ethernet cable.
Thanks!

try to connect manually from the drop down list select the configure other option.

enter password (try the following until it works): admin, password, public

Are you trying to set it up wirelessly? If so, try plugging your laptop into the router directly to do the initial setup.

BTW, I lived in Germany for 4 years. We came back in 2008 and miss it.

Tried that in Airport Admin Utility. Again I got the message that the computer can't read Airport's configuration. So frustrating!

I tried plugging Airport directly into my computer with an ethernet cable and still the configuration can't be recognized. Again, this all happened after a factory reset. What happened?!!?!

I would try to reset it again and if that didn't work I would try to see if I could re-flash the firmware. Something is certainly not right.
