Apple has released an update to Configurator 1.2.1 to 1.3. The update removes very important functionality. In version 1.2.1 you could install mobile Profiles to as many devices as you could plug in. Now after the update you can only install profiles, one at a time.
I had home wifi routers in just about every classroom, plenty of connectivity to go around but there's a problem. When your device is connected to one signal it doesn't really like to jump to another even if the signal is stronger. So, if your connected to room 200 & you move to room 203 down the hall, if the iPad can still see it, it's not going to let go and connect to 203, unless you force it.
Next problem is in naming. Each router needs its own name. If you have 2 routers with the same name and the same password, it won't work. The pass might be the same but keys will be different which you have no control over. So if your schools routers are all named, myschoolwifi, and you walk down the hall, your iPad will try to connect but will just error out in some fashion. Might even say connected but will have no ideas how to actually communicate.
So, when selling us on the iPad program, Apple suggested, AeroHive.
Using our existing network, their team came in and mapped out our building and ended up installing 13 Access Points, through the halls.
