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.

  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?

  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).
