Since you need to connect wifi in NTU ,RPI use Linux system but our school wifi(NTUSECURE) is WPA2 Enterprise which inner authentication is MSCHAPv2 powered by microsoft. So we can not connect to our school wifi with just simple click so what we should to is to go to the config folfer ** cd /etc/NetworkManager/system-connections** and modify the config file ** sudo vim NTUSCURE ** add this line to it and save.Connect to wifi again.
