I have a wireless network of 12 Cisco 1121 WAPs. They are all configured identically. I can get an IP phone working on all APs. My Windows Laptop works on all APs. The issue is that recently, the Apple ibooks work on certain AP's. I can be near an AP and the ibook connects fine. I walk towards another AP and I loose the connection. It seems that certain APs none of the ibooks can connect. However, like I said above, my winxp laptop and my cordless IP phone work all over the building. Six months ago, all the ibooks connected, now it's hit and miss. neither cisco nor apple have any information that is pertinent. I have made sure the ports on the cisco 3550 that the WAPs connect to is programmed correctly, so I don't believe it is the switch. Any Ideas?
