    Sometimes you can’t connect after entering your credentials (full UU e-mail address and password). This is common among students or staff who have studied or worked in the past at another University or school.

    You can solve this by performing the following steps:

    Step 1 – Right-click the Start button and choose “Run” / “Run”

    Step 2 – Type the following and press Enter: netsh wlan delete profile name=”eduroam”

    Step 3 – Type the following and press Enter: netsh wlan delete profile name=”UU-visitor”

    Step 4 – Type Exit

    Now try again (see instruction above).

    For advanced users: You can use the command “netsh wlan show profiles” to see which network profiles are present on your laptop. It is advised to delete obsolete profiles of other educational institutes (in the same way as described above – deleting eduroam / UU-visitor).

    More information can be found on the Microsoft website.

  • Android and iOS devices

    Below are some tips for both Android and iOS devices

  • Since iOS version 9, a feature called “Wi-Fi assistence” has been introduced. When this feature is enabled, your phone or iPad (if equipped with SIM card) may use more mobile data (3G/4G) unexpectedly.

    We advice to disable this feature. To do so, watch the video below or:

    Go to settings, and “Mobile network”. Scroll down all the way, and uncheck the box “Wi-Fi assistence”.



    Android has the option to automatically switch between WiFi and mobile data.

    To prevent unexpected costs we advice to turn this option off.

    • Open the Wi-Fi settings
    • Press “Advanced”
    • Turn off “Switch to mobile data”

    Use the following setting to connect to eduroam:

    – For EAP choose: PEAP (this is standard)
    – At verification phase 2 choose: None
    – If the CA-certificate says “(not-specified)” leave it that way, if not choose “Don’t validate”
    – At identity fill in your own UU e-mail address.
    – You can leave anonymous identity empty
    – Password: your own solis-password
    – Click on “Connect” and start using eduroam

    You can select “Connect automatically” if you want your phone to remember the connection.
