I have a MacBook Air (13-inch, Early 2014). It is on OS X el Capitan version 10.11.2. Whenever I try to join the school wifi, it will say "The wifi network could not be joined. Try moving closer to your wireless router." However, my phone can join it and I can connect to my own wifi at home or my hotspot.
