WPA2 Enterprise Connection with no internet access

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

Can you provide IP details from a working client and the MBP?

Craig thank you for a response but it appears that I posted the question too soon.

Deleting the "System Configuration" folder did indeed solve the problem. However, I just assumed it wasn't going to work because the person who worked on the MBP before it was brought to me had deleted some of the entries in the System Configuration folder, not the whole folder and that didn't solve the problem. I posted the question before I actually went to the location to try it, but once I did try it at the location, it worked as it was supposed to.

I was just going to delete the question, but you have already responded so I will have to mark it as I solved it myself.

Thank you for taking the time to read and respond to the question.
