Connecting to Campus Wi-Fi: General Questions & Troubleshooting


 Connecting to the campus Wi-fi requires FortiNAC (Network Access Control) device registration and scan to be ran to make sure network requirements are met before devices are granted full Internet access on both GUWireless and GUGuest.

More Information

  •  Each Network ID is allowed 10 registered devices.
    • There are non-standard network IDs (ie, HRConsult, alumni99, etc) that do have a higher device limit. If it is a non-standard account used by multiple people a request can be made to increase the limit of devices on the network at one given time and it will be reviewed.
  • If the FortiNAC scan fails, you will have Internet access to download windows updates or anti-virus updates over the wifi.  Access to other websites will not occur until you have successfully passed the FortiNAC scan.
    • The Linux operating system is supported on the Gannon network. Gannon does require that Linux OS have an approved anti-virus software and up-to-date definitions installed. 
  • Beta versions of any operating system (Apple or Windows) are not permitted on the Gannon network.
  • Nintendo Wii Game console will not connect to the Gannon wireless due to the fact that the Wii device being old wireless technology from year 2006 is not supported on the Cisco latest wireless access points. 
    • The Wii U will connect and should go thru our normal process.

FortiNAC Error: "Microsoft Windows operating system is out of date"

  1. Restart the computer first in case it is in the middle of an update.
  2. Attempt to connect thru FortiNAC by navigating to
  3. If failed, run Windows Updates manually
    • Check manually by selecting the 'Start' button, then select 'Settings' Update & Security' > 'Windows Update' > Check for updates.
      • If failing, the laptop may need to be either hard-wired to the Internet or connected to another network to get the update


  • Cumulative updates may take a long time to download and install - especially if you have not updated in a long time.
  • You might need to restart your PC, multiple times, to finish installing some updates especially if cumulative updates are needed.  Save and close all of your files and apps before you restart so you don't lose anything.
  • The best way to ensure your PC is always up to date is to set 'Automatic Updates' to 'On' in 'Settings'>'Update Settings' and to leave your laptop plugged in overnight a couple of times a week.  Before running updates, plug your laptop in , go to 'Settings'>'Power & Sleep Settings' and ensure the PC is not set to go to sleep (set to 'Never').

Unable to Connect to Wifi- iOS Device Prompts to Download FortiNAC Agent

By default, endpoints running iOS 13 or higher use the same agent as macOS due to a default setting in Safari called "Request Desktop Setting".  This behavior can prevent the user from registering the device. 

Disabling the "Request Desktop Setting" setting in the iOS device.

  1. Click Settings > Safari > Request Desktop Website
  2. Deselect All Websites
  3. Close and reopen browser.

User should now be able to complete registration.

FortiNAC Error: Authentication failed 

  1. Make sure that you have the login correct (Network ID - Example: Smith001 and Gannon password)
    • Try to sign into Gannon portal with incognito/private window
  2. Clear browser history and try again to connect
  3. Try to connect with another browser

Macs Not Running FortiNAC

If FortiNAC won't run on a Macbook do the following:

  1. From the Apple menuopen System Preferences
  2. Click Security & Privacy
  3. You may have to click on the padlock and enter your computer's password to make changes.
  4. FortiNAC should appear near the bottom of the window, click "Open Anyway' for it to run.
  5. Exit Security & Privacy.

MacOS 13 (Ventura) has replaced System preferences with System Settings:

  1. From the Apple menuopen System Settings
  2. Click on Privacy & Security
  3. Scroll down to the Security section - You may need to click to allow the FortiNAC app to run
  4. Exit Privacy & Security.

FortiNAC Scan Runs Repeatedly

If a windows 10 laptop attempts to run FortiNAC every time a browser is open, even after passing a scan, check this setting:

Wireless Icon > Network Settings > Manage WiFi Settings > Turn off “Random Hardware Addresses” and then reboot the PC.

This setting, when turned on, randomly assigns MAC addresses to the device. FortiNAC identifies MAC addresses with a device. So if this setting is turned on, every time a browser is opened on that device, FortiNAC will need to scan.

FortiNAC Error - Anti Virus Software Not Recognized​​​

If a FortiNAC scan fails and the anti-virus software is current and up-to-date follow these instructions.  Sometimes when anti-virus software vendors update their product there is a delay before our FortiNAC (Network Access Control) recognizes that version. 

If you are failing the FortiNAC scan and your Ant-Virus is up to date, it is recommended to remove the software and use a different free one while waiting for it to be recognized by FortiNAC.

Trouble with Online Games: Low Bandwidth

Games receive the lowest priority of bandwidth allocation. Academic use takes priority.

Requests to Open Ports or Enable Port Forwarding for Online Gaming

  1. If the communication is initiated from within the Gannon network (Outgoing) then all ports are open and not blocked or restricted
    • For example they are connecting to an Online game that is hosted on the Internet.
  2. If the communication is initiated from outside the Gannon network to an internal device on the Gannon network then all ports are blocked.
    • The request to open ports or enable port forwarding will not be allowed as this is a security risk to the Gannon network and to other student devices.
    • For example they want outside devices to connect to their hosted gaming site which in essence allows any device on the Internet to connect to any device on the Gannon network without any security protection or scanning by the firewall.

Explanation of port forwarding:

A port forward is a way of making a computer on your home or business network accessible to computers on the internet, even though they are behind a router or firewall. It is commonly used in gaming and after you have forwarded a port you are said to have an open port.
