Not sure why, but I'm still having problem with my AEBS and AE (2units). the sound tends to cut out every 5/10mins. Each time I enter the AEBS settings this window pops up. The AEBS & AE7s is the latest version, purchased just a few weeks ago from the apple store. My Macbook pro is the current version 2.53 (13inch) with every update under the sun using snow leopard I keep getting this error when I enter the settings, I've installed the airport from CD, but it tells me it cannot as the version i have installed is newer or the same. Anyone having the same problem?
