Troubleshooting GTwifi on Windows 7

This document will provide some basic GTwifi troubleshooting information for Windows 7. This example is assuming you are running Windows 7 with a working wireless adapter 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 issues.

If you are uncomfortable making these changes or this document does not solve your problems, please visit the OIT Technology Support Center on the first floor of the GT Library.

NOTE: Certain software packages such as "McAfee Security Center - Consumer Version", "Norton Internet Defender", or other firewall/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 connectivity, 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. We always recommend having at least the OIT supported McAfeee Antivirus available for free for all GT faculty, staff, and students.
