Dec 20, 2013 9:39 PM in response to Jeffrey.scott.hillby LowLuster,Yes a lot of people have had problems with Mac notebooks dropping a WiFi connection to many different Wifi networks. If this is a Retina screen MBP it is more common then on the Non retina screen model but it can still happen on the standard model. It is an Apple problem that they just refuse to acknowledge claiming it is a Router problem and suggest to buy a Apple Airport extreme, which in your case isn't possible.
Your only option is to take your Mac into an Apple store and hopefully it will happen when connecting to the Apple stores WiFi system so you can show them what is happening. Otherwise they will only state it is the schools problem.
There are numerous threads about WiFi connectivity problems with all types of Mac computers on this and other Apple forums.

If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon.

From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
