IITD Campus Wi-Fi

  1. IITD campus is equipped with state-of-the-art Wi-Fi based on Wireless Controllers for the entire academic areas/ Guest houses and Hospital. These services are accessible with SSIDs namely IITD_WIFI, IITD_Secure_GUEST and eduroam. A total of ~2000 Access Points (dual-band 802.11a/g/n/ac/ax) are available in Academic Area, Hostels, Hospital and Guest Houses.
  2. We use IEEE 802.1x (WPA2 Enterprise ) based encryption for security on IITD_WIFI, IITD_Secure_GUEST and eduroam. For authentication, we use the EAP method EAP-TTLS with PAP as the inner-tunnel method as well as the EAP method PEAP with MSCHAPv2 as the inner tunnel method. i. IITD_Guests are "Unsecured network" but uses HTTPS authentication based on captive portal technology developed in-house.
  3. The RADIUS servers for EAP-TTLS  and EAP-PEAP uses the IITD LDAP, Kerberos systems and/or Windows Active Directory for user authorization and authentication at the back-end. Users can connect to the Wi-Fi network using their LDAP ids and Kerberos passwords. Upon successful authentication, clients are configured using DHCP .

  5. Man-in-the-middle attacks and eavesdropping are easiest with wireless networks, so please make sure that you have read the Certificates section and have installed the IITD CA certificate in your Wifi client software.
  6. Please report problems, if any, to sysadm@cc.iitd.ac.in
  7. Please note that each user is permitted at most 8 distinct devices he can use on the IITD Wi-Fi system in any 90 day period.
