If you have AP version 12.3(4)JA or higher, then you need 1.09 firmware or higher on the 7920 or roaming will not work. For site survey, should use non-overlapping channels (i.e. 1,6,11). Ideally would like to roam to a non-overlapping channel (i.e. 1 to 6 or 11). Can easily just use 7920 and ensure you have signal of 30 or higher for both APs where they overlap.
Yes. Should only use non-overlapping channels even though you have more than 3 APs. 7920 gives precedence to discovered non-overlapping channels.
Recommend 2.01 sw for 7920. Just need to ensure that you tune your network for 11mbps and you have -67dbm of signal always w/ 25db SNR. For adequate overlap, you can either just walk around and ensure you have RSSI of 30 or higher where the 2 APs overlap or you can use tools such as Airmagnet Surveyor (www.airmagnet.com).
