Troubleshooting GTwifi on Mac OS X 10.6

This document will provide some basic GTwifi troubleshooting information for Mac OS X 10.6 (Snow Leopard). This example is assuming you are running Mac OS X 10.6 with a working AirPort card that is turned on.

These are listed in order of difficulty as well as recommended starting places to diagnose where in your configuration there may be issues. You may only need to perform one or two of these in order to resolve your OSX issues.

NOTE: Certain software packages such as Peer Guardian or other network security related software may interfere with basic network connectivity. Temporarily remove these packages, reboot, and attempt to connect again. If you find that your product is interfering with your network connecivity, you may need to find an alternate method to your protect your system. OIT Technology Support may be able to assist you in configuring your product or system.

  1. Turn AirPort off and back on.

  2. Is "GTwifi" at the top of your "Preferred Networks"?
    1. Click the AirPort icon in the upper right hand corner of your menu bar.
    2. Select from the pull down menu "Open Network Preferences..."
    3. Drag "GTwifi" to the very top of the "Preferred Networks" listing on the "AirPort" tab.

  3. Is IPv4 configured for "Using DHCP" and IPv6 "Off" under your "Network Settings" on the "TCP/IP" tab?
    1. Click the AirPort icon in the upper right hand corner of your menu bar.
    2. Select from the pull down menu "Open Network Preferences..."
    3. Click the "TCP/IP" tab.
    4. Make sure "Configure IPv4" has "Using DHCP" selected.
    5. Make sure "Configure IPv6" has "Off" selected.

  4. Reboot your Mac.

  5. Is AirPort showing other available networks (GTvisitor, GTwifi)? If not, it could be a hardware issue with your AirPort card.

  6. Are you in an area where "GTwifi" is available? "GTwifi" is available at the same locations as "GTother" and "GTvisitor".
  7. If the AirPort icon in your menu bar looks like this:

    Your Mac may be given a "self assigned" address that usually starts with 169 (like shown in screenshot below). In most cases this can be fixed by refreshing your connection by switching AirPort off and back on again. Your connections settings may be improved by making additional configuration changes to your "GTwifi" settings as detailed below.

    1. Visit your 802.1X settings by opening "System Preferences".
    2. Click on "Network".
    3. Click the "Advanced..." button.
    4. Click on the 802.1X tab. Verify that PEAP is the only protocol enabled.
    5. Once configured this way, disable and then enable your AirPort. If this does not improve your situation, continue to the next troubleshooting suggestion.

  8. Clean up cluttered network settings:
    1. Open "System Preferences"
    2. Click on "Network"
    3. Click on the padlock if it is locked and authenticate if required to do so.
    4. Click on the "Advanced" button.
    5. Click on "GTwifi" in the preferred Networks list and click the [-] button to remove it.
    6. Click on the "802.1X" tab
    7. Remove each "GTwifi" profile under "User Profiles"
    8. Click "Apply"
    9. Turn off AirPort
    10. Open "Keychain Access". You can find where this is by using Spotlight.

    11. In the upper right hand corner of "Keychain Access" application, search for "gtwifi".
    12. Delete any related entries.
    13. Reboot your Mac.
    14. When it boots up again, follow the GTwifi configuration instructions to create your connection.
