After CoB today, I was able to backport my 220 from V8 to 7.506 for testing.
I didn't get much time to do anything other than a very simple setup to start with because it was late and I wanted to go home. [:)]
Installed a single AP10 and set the wireless to bridge to the LAN. For the first client test, I used an iPad. Had to switch to AES and TKIP, as the iPad apparently doesn't support AES. After I made that switch, things worked well.
I'll begin working with radius authentication, multiple APs, isolated network, and different clients after the weekend.
