Step by step guide for the 802.1X WiFi on iOS

To ensure a clean installation, make sure to remove any existing old copies of our profile.
This step is only needed if you already have an old version of our 802.1X configuration profile and wish to reinstall a new one.

Tap VPN & Device Management, you will be presented with all installed and pending configuration profiles currently on your system.
Tap the one called 802.1X (GSG) and press Remove Profile. You will be asked for your device Pin. Enter it and confirm the removal of the profile.
If there is no profile called 802.1X (GSG) on your device, you can skip to step 2.

In order to use the WiFi at our building, you will need to download the profile first. Please select the matching type of profile (pick the first one if unsure):

If you have multiple devices connected to your Apple ID, you might be asked on which device to install the profile, in that case, choose the appropriate device (most likely „iPhone“).
The profile will then be downloaded but still needs to be verified and installed in the settings app.
