Help/Support OS X El capitan: WPA2 enterprise is not working

[ThePianoGuy 3k 14]

We have macbooks at our school but  WPA2 enterprise is not working with some macbooks. It says it can't connect to the internet even the Wi-Fi signal is very strong. Our admin have fully checked the network and there is nothing wrong with it.

 

WPA2 enterprise is a network that teachers and student can login with their own username and password. it's NOT like WPA2 personal that you only need a password to connect.

 

I have deleted the disk and reinstall El Capitan 10.11.4 from USB, but it does not solve the problem.

 

We can't simply use guest Wi-Fi because it keep f**king asking to login every 1 hour and after computer on standby.

 

WPA2 enterprise is working perfectly on Windows Phone, Android, iOS, Linux and Windows... except Mac OS X. Why?

 

 

 

i tried to connect to the internet in recovery mode and it succed showing login popup but still getting can't connect error

When negotiating a TLS/SSL connection with Diffie-Hellman key exchange, OS X El Capitan requires a 1024-bit group or larger.OS X El Capitan will not connect to a server that allows negotiation with a 512-bit or smaller group.These connections include:        ⁃   Secure Web (HTTPS)        ⁃   Enterprise Wi-Fi (802.1X)        ⁃   Secure e-mail (IMAP, POP, SMTP)        ⁃   Printing servers (IPPS)

this is ElCapitan's notes, ios 9 has same problem and same notes

Apple support (in germany) said they can't do anything with it and their english sucks. I already asked them in Mac forums but didn't got any replies

We just talk about that and he said, some Macbooks can connect to WPA2 Enterprise and some of Macbooks can't.  All macbooks are the same model, same OS version, and everything updated to the latest version. I know it sounds weird. now we are confused and don't know what to do.....
