WiFi Access

Everyone who is in posession of valid login credentials to central systems of the c.s. dept. or the b-it has the opportunity to use our wifi networks to access the local ressources and of course the internet. Please follow these instructions to gain access to the wifi network.

We secured our WiFi Network mainly via TTLS, so make sure you have the necessary root certificate installed and do not forget to check the fingerprints of the used Certificates. Here are the current fingerprints:

Hashtype Fingerprint
MD5 DC:B5:69:1A:6D:B0:E7:8E:01:84:8A:6E:51:C1:AC:E3
SHA1 55:9F:C9:EA:AF:E7:9D:0C:99:C4:C5:2B:B5:68:68:EA:3E:0B:FA:F3
SHA256 20:A4:71:92:93:F7:43:A5:AD:81:77:5C:D3:70:52:2F:8C:F2:BB:… …AA:60:D5:68:5E:0A:16:81:76:AC:8C:E1:26

Generic Parameters

Please use the following connection parameters:

Parameter Value
SSID 802.1X
WPA-Type WPA2 Enterprise
EAP-Method TTLS
Keytype AES
Phase 2 Authentification PAP
Root Certificate Telekom Root CA 2
valid CN (Common Name) Radius-Server Certificates ise0.informatik.uni-bonn.de

Identity username@(bit|informatik)2).uni-bonn.de
Authentification Server ise0.informatik.uni-bonn.de, radius.informatik.uni-bonn.de

Windows 10

Just select the SSID 802.1X from the list of available WiFi Networks, verify the certificate fingerprint and enter your username (including the correct domain3)) and password.

Android

For recent Android versions (>4.0), the configuration of wifi at the computer science dept. is rather simple. Just connect to the SSID “802.1X” and fill in the configuration dialog with the Values from the table above (→ Generic Parameters).

If your system cannot use the root certificates installed to verify the wifi certificate, you have to download the necessary root certificate via mobile network and install it as a wifi Certificate. Do not install it as a VPN certificate, it will not be available to you for wifi configuration!
