Please note that you need an extra password to use the TU Dortmund's wireless networks. In case you do not have an extra password for the wireless networks or you forgot yours, you can create a new password on this page:

Configuration

First download the "T-Telesec Globalroot Class 2" certificate from www.pki.tu-dortmund.de

Save it in /usr/local/share/ca-certificates . If this folder does not already exist, create it and save the certificate in it.

Run sudo update-ca-certificates

Run "sudo wpa_cli scan" to trigger network scanning. Wait a few moments and then run "sudo wpa_cli scan_results" to get a list of available networks.

If you receive any errors try running "iwlist scan" to get a list of available networks.

To add or change a network entry, edit  "/etc/wpa_supplicant/wpa_supplicant.conf" (or create a file ending with .conf in /etc/wpa_supplicant/ ). 

## TU Dortmund eduroam Network
network={
  ssid="eduroam"
  key_mgmt=WPA-EAP
  pairwise=CCMP
  group=CCMP TKIP
  eap=PEAP
  ca_cert="/path/to/the/certificate/telesec.crt"
  domain_suffix_match="radius.tu-dortmund.de"
  phase2="auth=MSCHAPV2"
  identity="smxxxxxx@tu-dortmund.de"
  password="YourPassword"
  priority=1
}

Use your UniAccount username as identity and your wifi passwort as password.
Which username and password should I use?

We suggest to change wpa_supplicant.conf's permissions so that only the root user might read or change them. You can change the file's owner and group with "chown" and "chgrp".

Use "wpa_supplicant  -B -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0" to test your settings. 
(wlan0 was the default name for a wifi interface. Your wifi interface might be named different. To get a list of possible interfaces run "ip addr"). Run "sudo wpa_cli status" to see if you're connected to a wifi network.
