WPA2 802.1X Wifi with Ubuntu 18.04.3 LTS

  • 772

I go to a public place where a wifi connection is possible. It is a WPA2, 802.1X connection. I have a username and a password, but when I simply find that network under the regular 'Select Network' (in Ubuntu) and try to connect, it fails.

I'm looking for some kind of config file, where I can manually enter my username/password, but I can't find the needed config file. I found this https://www.nowiressecurity.com/configure-8021x-authentication-linux page, but it doesn't specify the exact location of the config file.

  1. According to https://help.ubuntu.com/community/Network802.1xAuthentication the configuration is located on /etc/wpa_supplicant.conf— IIRC the newer Ubuntu distribution require to install wpasupplicant packages.

    sudo apt install wpasupplicant

    Then you can start editing the configuration files.

    sudo nano /etc/wpa_supplicant.conf

    You can also create a new connection through Ubuntu's network-manager, then changes the WiFi security to Dynamic WEP (802.1X).
