I have a simple "yes/no" question for the group that I'm having trouble confirming on Apple's support site. If you're using 2 or 3 Airport Expresses together as a wireless distribution system (i.e. one as a base and one or two as relays and not simple "wireless clients") do you have to use the WEP encryption protocals rather than the WPA? Yesterday I tried to toggle a new Airport Express in to an existing Airport Express base station to use as a signal relay and as an iTunes node and it forced me to change the encryption on my base station Express unit from WPA to WEP.
