No help to offer, but here at Lowe Towers, I have 3 cisco access points
running WPA2-Enterprise ( with RADIUS servers and certificates ) and the
iPAD1 and iPod touches / iPhones all just figure it out and request
credentials and connect.

Are the access points covering different areas? Do the various toys
connect to the strongest signal or do they have a favourite that they try
to connect to irrespective of signal strength?

I have a wireless router and separate access point covering overlapping
areas and although I'm not using 'i' products (just yet) I have had bother
with:

1. A Blackberry which has a priority list for wifi connections trying to
connect to the favourite even if it is nearly out of range and the second
favourite is much closer.

2. A laptop preferring to connect to the last connected node rather than
the strongest which makes it a pain when moving between home to home
office.

Win7 is sensible enough to decide that AP with the same network ID are the
same network and use the best signal.
Of course if they have different IDs it treats them as different networks
and tries to connect to the last used one.
