I'm trying to get internet access at the local high school for a students MacBook Pro with El Capitan. She can connect to all other wireless connections and get internet access. However when she connects to the school wifi which has WPA2 Enterprise, she enters her user name and password and makes the connection, or at least it says "connected" but when she tries to access a website using IE or Chrome it will not display the page. There is no distinct arror message and all other wireless connections work fine.
I have reset the networking on the MBP by removing the "System Configuration" folder under System Preferences and restarted the computer and that didn't help.
Unfortunately I can't have the school restart the router and none of her friends have a problem with getting internet access. So I'm looking for other suggestions for what I should be checking out.
Thank you,
Craig
