I have had issues with Mac's and certain brands of AP - Linksys being the main one that breaks with Macs pushing through too much data.
Neochick: Well, asked the classes about the swapped macs today.
The good macs are working fine in the bad room.
Of the bad macs, one is still not keeping the password, and the other one occasionally disconnects, but for the most part is playing good.
Trying to get a portable HDD for the school so i can try some new clones. Should hopefully have it within the week.
Also, router does not assign IP's, our server does that instead.
