Unable to connect to the TTUguest Wi-Fi network in macOS Monterey or Big Sur


Symptoms

You have configured your Mac to connect to the TTUguest wireless network according to the published instructions, but you are still unable to connect.

Cause

There are multiple possible causes for failed connections to the TTUguest Wi-Fi, even if the connection was configured correctly.

Resolution

1) In your Mac's menu bar, click the Wi-Fi icon. Then, slide the switch next to "Wi-Fi" to the off position (to the left).

2) Slide the switch to the on position (back to the right) to enable Wi-Fi. Check to see if the problem has been resolved. If not, proceed to the next step for additional troubleshooting.

TIP: If you connect to TTUguest Wi-Fi in one location and then move locations, your Mac may attempt to maintain its connection with the wireless access point at the previous location. This can result in a slow connection or the appearance that there is no connection at all. To resolve the problem, simply disable Wi-Fi on your Mac and enable it again by repeating the two steps above. This will cause macOS to re-establish a connection using the closest wireless access point.

3) Open the Keychain Access app. One way to do this is by going to Launchpad, going to the Other folder, and clicking Keychain Access.

4) Delete any certificates or passwords related to TTUguest from all applicable keychains, including Login, iCloud, System, and System Roots. Click once on the desired item to select it. Then, press the delete key on your keyboard.

TIP: To delete multiple certificates and passwords, click on each one while holding the command key on your keyboard. When you are done selecting, press the delete key on your keyboard.

11) Click the DNS tab and locate the "DNS Servers" field. Use the minus sign () button to remove any entries that were manually added.

NOTE: Manually-added entries are easily identifiable because they are the ones that the system will allow you to remove. Default DNS servers assigned by DHCP will be grayed out and cannot be removed; this is expected.
