Problems setting up WDS with old AX and new AEBS

Question

Hi all,
after buying a new AEBS last week, I want to put my old AX back into service. Here's what I have planned:
The cable modem sits in the living room near my stereo. The AX should connect to the cable modem and the stereo and be the main station in a WDS network with the AEBS. The AEBS will be in my study as a remote station to the AX.
Sounds trivial, but apparently it isn't I have spent the evening setting up the two base stations again and again. For some reason, the Airport Utility cannot see both stations at once as soon as they are configured. The AEBS won't find the AX even though the MAC address is correct.
I tried with and without WPA/WPA2, but I cannot figure out what's wrong
Could someone please give me a step by step guide of what to do? I am quite desperate by now...
Cheers from Switzerland

Well, what can I say... Of course, I could not give up
Finally I got it to work. For future reference, here's how:
I first set up the AEBS to create a network, then used the Wizard of the Airport Utilitiy to add the AX as a WDS-device (it sets up the whole WDS automatically). Then I flipped the settings - set the AX to be main and the AEBS to be the remote.
I also had to adapt the Internet-Settings. Both base stations were set to bridge-mode, which doesn't work in my case because I only get two IPs from my ISP. So, I set the AX (the main) to share an internet connection and get its IP by DHCP. The AEBS on the other hand needed to get an IP manually (outside of the address space of the DHCP server created by the AX, but within its subnet).
After that it all worked - even AirTunes The AEBS now sits on my desk and the AX provides internet from the living room.
Cheers,
