+====== Set up Wi-Fi on Linux – Ubuntu, NetworkManager, wpa_supplicant ======
+===== Ubuntu, NetworkManager =====
+When using a GUI, it is likely that you use NetworkManager for network configuration.
+<note important>
+**It is important to set up RADIUS server identity verification, as it will give you protection against rogue Wi-Fi access points and protect your password as well.** That is why you should take the time to set your Wi-Fi connection properly. You will find verified walkthrough below.
+</note>
+  - Run command ''nm-connection-editor'' (Advanced Network Configuration).
+  - Expand the **Wi-Fi** category and look if you already have an existing Sincoolka profile - it might be a good idea to remove it with a **-** button (minus sign) if it does not work. \\ {{:en:verejne:sit:wi-fi:ubuntu-nm-step1.png?nolink|}}
+  - Then, click the **+** button (plus sign) in the bottom toolbar.
+  - In the **Choose a Connection Type** window, pick **Wi-Fi** from the list. Then click the **Create...** button \\ {{:en:verejne:sit:wi-fi:ubuntu-nm-step2.png?nolink|}}
+  - A window for describing network configuration will open.
+     * Fill out the name of the profile (can be anything, e.g. Sincoolka).
+     * Switch to the **Wi-Fi** tab and fill out these - **SSID**: ''Sincoolka'' or ''Sincoolka 5G''. From the **Devices** list, choose your Wi-Fi adapter. \\ {{:en:verejne:sit:wi-fi:ubuntu-nm-profile-wifi.png?nolink|}}
+     * Switch to the **Wi-Fi Security** tab and set up the following:
+       * **Security**: WPA2-Enterprise
+       * **Authentication**: Tunneled TLS
+       * **Anonymous identity**: ''anonymous@sin.cvut.cz''
+       * **Domain**: ''radius.sin.cvut.cz''
+       * **CA certificate**: either browse to ''/etc/ssl/certs/Comodo_AAA_Services_root.pem'', or [[en:verejne:sit:cert|download and save it]] (download format PEM)
+       * **Inner authentication**: PAP
+       * **Username**: use your SIN username or SIN email (find it after logging in to [[https://sinis.sin.cvut.cz|SINIS]])
+       * **Password**: the same as for your SINIS login. \\ {{:en:verejne:sit:wi-fi:ubuntu-nm-profile-sec.png?nolink|}}
+     * Confirm your settings by pushing the **Save** button.
+<note important>The picture has the certificate wrong! It's for illustration purposes only.</note>
+Now, your connection should be all set for secure Wi-Fi browsing.
+===== wpa_supplicant =====
+WPA Supplicant is an utility which enables WPA security support for Wi-Fi in Linux. NetworkManager uses wpa_supplicant internally.
+In case you want to set up a wpa_supplicant profile manually, we have prepared a Sincoolka network definition below.
+Please [[en:verejne:sit:cert|download the proper **CA certificate** first]] and save it. You will enter the path to this file in the wpa_supplicant configuration profile.
+<file wpa_supplicant wpa_supplicant.conf>
+network={
+    ssid="Sincoolka"  # or Sincoolka 5G
+    scan_ssid=1
+    key_mgmt=WPA-EAP
+    eap=TTLS
+    # path to the downloaded CA certificate
+    ca_cert="/etc/cert/sin-wifi-ca.pem"
+    domain_match="radius.sin.cvut.cz"
+    phase2="auth=PAP"
+    pairwise=CCMP
+    group=CCMP
+    # Your credentials
+    identity="jiri.novak@sin.cvut.cz"
+    anonymous_identity="anonymous@sin.cvut.cz"
+    password="YourStr0ngPa$$word"
+}

+===== iwd =====
+//Contributed by our member Artem Poliakov (poliaart <at> fit.cvut.cz)! Thanks!//
+[[https://iwd.wiki.kernel.org/|iwd]] is a wireless daemon for Linux which aims to utilize features provided by the Linux Kernel to the maximum extent
+possible. It can work in standalone mode or in combination with comprehensive network managers.
+If you want to connect to Wi-Fi using iwd, you need to place file called ''Sincoolka.8021x'' or ''Sincoolka 5G.8021x''
+(depending on which network you'd like to connect) under ''/var/lib/iwd'' directory. The suggested contents can be found below.
+Please [[en:verejne:sit:cert|download the proper CA certificate first]] and save it. You will enter the path to this file in the iwd configuration profile.
+<file iwd Sincoolka 5G.8021x>
