4. After a while, a window appears to enter your login credentials. Enter your school mail and password (the ones you registered with to SINIS).

   CC:77:A0:85:88:CA:0C:F8:89:15:28:FB:3B:1D:70:B2:CA:10:B3:8D
   (it is sufficient just to verify first few letters)
   and click Connect or Accept.

5. Do NOT close the window, click on Change connection settings instead.
   
6. Check and correct the following settings on the Security tab:
   • Network authentication method - Microsoft: Protected EAP (PEAP) or TTLS
     
   • Settings
     • Check Verify the server's identity by validating the certificate checkbox.
     • Check Connect to these servers … checkbox and enter radius.sin.cvut.cz to the textbox below.

     • In Select Authentication Method, select Secured Password (EAP-MSCHAP v2);
