This guide will explain some basic troubleshooting techniques to resolve connectivity issues on the eduroam network. This guide is presented as a list of possible solutions, appearing in order of easiest to hardest. It is recommended you try each possible solution in the order presented here.

Toggle Wi-Fi On/Off
Forget and Re-Connect to eduroam
Verify IP Configuration Settings
Reset TCP/IP Network Stack

Important Note: If you have previously conencted your device to the GTwifi, GTother, or GTvisitor networks, you should delete/forget these wireless configurations prior to joining the eduroam network. Only one GT network should be configured on any device at a given time. Follow the the Forget and Re-Connect instructions, to forget networks on your device.

Toggle Wi-Fi On/Off

Some devices have a hardware switch or keyboard function to enable or disable the wireless radio. If your device has such a switch, try turning it off and then make sure it is turned on before continuing. You can also enable/disable the wireless adapter in Windows through the control panel. To do this:

  1. Right-click the wireless icon in the system tray, and click "Open Network and Sharing Center".
  2. In the left sidebar, click "Change adapter settings".
  3. Find your wireless adapter in the list of adapters. Names will vary depedning on your hardware, but the name will usually have the word "Wireless" or "Wi-Fi" in them. The icon will also show wireless signal bars. Once you have located your wireless adpater:
    1. Right-click the adapter and select "Disable".
    2. Wait a few moments for the wireless radio to be disabled. Once the icon has been greyed out, the radio has been disabled.
    3. Right-click the adapter again, and select "Enable".

Forget and Re-Connect to eduroam

If your device is having problems associating with the eduroam network you can forget the wireless connection and try re-connecting from scratch.

  1. Click the wireless icon in the system tray.
  2. In the sidebar, right-click eduroam in the list of available networks, and click "Forget this network".
  3. Likewise, any other GT networks that you have connected to before, right-click those and select "Forget this network".
  4. Now, left-click eduroam from the list of available networks and continue connecting as if it was your first time.

Verify IP Configuration Settings

If you are able to associate your device with the eduroam network, but are unable to get to the internet, you may need to adjust your device's IP settings. This problem is usually indicated by the "Limited Connectivity" message displaying after connecting the network. Verify your settings are configured as below:

  1. You will need to open the properties of your wireless adapter. You may do this by right-clicking your wireless adapter in the "Network Connections" panel of Control Panel, and selecting "Properties". You can follow the steps in the Toggle Wi-Fi On/Off section to get to the "Network Connections" panel, or use the following shortcut: launch the run dialog box by pressing the Windows key + r on your keyboard, type "control netconnections" (without quotes), and press "OK".
  2. From the properties window, highlight "Internet Protocol Version 6 (TCP/IPv6)" in the menu
    1. Make sure the checkbox next to "Internet Protocol Version 6 (TCP/IPv6)" is checked.
    2. Click the "Properties button".
    3. Make sure the "Obtain an IPv6 address automatically" and "Obtain DNS server address automatically" radio buttons are selected, and press "OK".
  3. From the properties window, highlight "Internet Protocol Version 4 (TCP/IPv4)" in the menu
    1. Make sure the checkbox next to "Internet Protocol Version 4 (TCP/IPv6)" is checked.
    2. Click the "Properties button".
    3. Make sure the "Obtain an IP address automatically" and "Obtain DNS server address automatically" radio buttons are selected, and press "OK".
  4. Press the "Close" button to apply these settings.
  5. If you made changes to these settings and do not see any improvements after closing the properties window, you may need to enable/disable your wireless card or reboot your device.

Reset TCP/IP Network Stack

If you are still having issues after verifying your IP settings, you can try to reset the entire TCP/IP network stack in Windows.

  1. Open the start screen, and type "cmd".
  2. Right-click "Command Prompt", and click "Run as Administrator".
  3. When prompted "Do you want to allow the program to make changes to this computer", click "Yes".
  4. Make sure you see "Administrator: C:\Windows\System32\cmd.exe" in the title of the resulting window.
  5. At the "C:\Windows\System32\>" prompt, type the following commands:
    netsh int ip reset C:\netsh.log.txt
    netsh winsock reset
  6. After both commands successfully execute, reboot your device, and try re-connecting again.
