Print PDF


  1. The CSC has released the IITD campus Wifi -  IITD_WIFI, IITD_GUEST and eduroam in early 2015, IITD_WIFI1 and IITD_WIFI2  from April 15,  IITD_WIFI3 from May 12, 2010, and IITD_Guests from November 22, 2010. EDUROAM has been started from October 18, 2013. Campus Wifi namely IITD_WIFI1, IITD_WIFI2, IITD_WIFI3, IITD_Guests and EDUROAM are being replaced by IITD_WIFI, IITD_GUEST and eduroam as CSC is replacing Aruba Wifi Solution with Cisco Wifi Solution.
  2. The IITD campus Wifi was based on controllers and access points from Aruba Networks which are now being replaced with redundant controllers and access points from Cisco.  Currently a total of xxx Cisco Access Points (dual-band 802.11a/g/n/ac) has been installed in the buildings namely CSC (xx), administration, Multi-Storey (xx), Block 1A (xx),  Block 2A (xx), Block 2B (xx), Block 2C (xx), Block 3A (xx), Block 3B (xx), Block 4A (xx), Block 4B (xx), Block 5A (xx), Block 5B (xx), SIT (xx), Bharti (xx), Textile (xx), Library (xx) and IDDC (xx). 173 Aruba Access Points have been switched off, 51 Aruba Access Points are still "on" in Block 1C (3), Block 6 (14), Synergy (3), Vishwakarma (12) , FGH (9), RCA (1), MGH (5), Design Studio (1) and Hospital (3).
  3. We use IEEE 802.1x (WPA2 Enterprise) based encryption for security on IITD_WIFI, IITD_WIFI1, IITD_WIFI2, and IITD_WIFI3. For authentication,  IITD_WIFI, IITD_WIFI1, and IITD_WIFI2 use the  EAP method EAP-TTLS with PAP as the inner-tunnel method. This method is natively supported in Mac OS X and Linux. Many versions of Windows also support it natively. In case this method is not supported in your version of Windows, you may download and install the free SecureW2 version available at the CSC web-page. IITD_WIFI3 uses the EAP method PEAP with MSCHAPv2 as the inner tunnel method which is supported natively on Windows platforms and is commonly available on mobile phones and other hand-held devices. Use of PEAP/MSCHAPv2 will require registration of password with the Microsoft Active Directory.  IIT_GUEST and IITD_Guests are "Unsecured network" but uses HTTPS authentication based on captive portal technology. eduroam and EDUROAM havw been programmed to use either TTLS/MSCHAPv2 or PEAP/MSCHAPv2.
  4. The RADIUS server for EAP uses the IITD LDAP and Kerberos systems for user authorization and authentication at the back-end. Users can connect to the Wifi network using their LDAP ids and Kerberos passwords. Upon successful authentication, clients are configured using DHCP.
  5. For configuration details in your favourite laptop OS, please follow the links from the Resources menu on the left.
  6. The locations where the Wifi access points have already been installed can be seen here. The progress of the Wifi deployment can be monitored by following this link which will be updated on a daily basis.
  7. 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.
  8. Please report problems, if any, to
