I have a total of 3 airports attached to a cart with approx. 30 Mac ibooks (white 12") running 10.3.9. I have a OSX server running 10.4.11. When the users attempt to log into the network from the ibooks, it is extremely slow and then not all of the ibooks will connect or they freeze up. The airports are the somewhat older extreme versions. I have upgraded the firmware on the airports to the most current version available. I set them up to share an ip to the ibooks using NAT at first, but am now considering maybe just soley using DHCP if anyone thinks that will help. Anyone else have this problem?? Is there a limit on how many ibooks can connect to the airports? I think that 30 ibooks and 2 airports should be plenty. The problem is also very sporatic and not limited to just certain ibooks. Sometimes they work, sometimes they don't. Any help would be EXTREMELY Apreciated. Thanks.
