    Some virusscanners may cause connection problems. For instance, you might be succesfully connected but have no internet access, or you can’t connect at all.

    We advise to temporarily disable your virus scanner to troubleshoot the problem and try to connect to eduroam again. If you succeed in connecting to eduroam, refer to your virus scanner documentation and settings to solve the problem.

    Don’t forget to turn your virus scanner back on.

  • Microsoft Windows

    Below are tips for eduroam and Windows.

  • When having problems, first check the FAQ “Configure eduroam via the Configuration Assistant Tool”. If that did not solve the problem, continue reading. 

    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.

    • Remove the old eduroam profile from the Windows network settings.
    • Right-click the wifi icon in the Windows taskbar and select Network & Internet Settings

    You will have to ‘forget’ the network before you can connect again with your new credentials. You can do this by following the steps below:

    • Right click on the Wi-Fi icon on your taskbar
    • Go to “Network and Internet Settings”
    • Go to “Manage know networks”
    • Select eduroam and click on “Forget”
    • Now turn your Wi-fi off an on
    • When you reconnect with eduroam it will ask for your credentials: now fill in your UU email address and new solis-password.
  • Mac OS, iPhone and iPad (Apple)

    Do you have a Mac, iPhone or iPad? Look in this section for tips surrounding eduroam. These are written expecting you to have the latest version of the operating system.

  • 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

    Do you have an Android phone or tablet?

    The look of Android differs depending on the manufacturer or model. The look of a Samung phone will look different than for example Motorola or LG. The function will generally be the same, but it can happen that the tips in this section won’t apply to you.

  • 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.

    Go to the ‘Settings’ of your phone, and proceed to ‘Wi-Fi’. Tap on ‘eduroam’ (You might need to tap and hold), and select ‘Forget Network’. After this, you can connect again using this manual.

    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”

  • Ubuntu (linux)
