I noticed the mac was freezing frequently. When I looked at the system.log file, I noticed it was bouncing between the two APs.
So... I turned off the AP10 and I still noticed it is reporting Roamed or switched channel every few minutes. Is this normal? My AP30 is fixed channel (11) and I found a file on the mac that is reporting 11. Each time it reports the 'new' BSSID it is actually the same.
