Go to System Preferences as shown above.

Make sure you're on the WiFi Connection on the left side bar in this menu.

On the Wi-Fi tab, click on every network except for UWNet and EduRoam. Once they're highlighted, click the minus button to remove them from the list.
If there are networks that you would like to keep on the list, like a WiFi connection at home, you may choose to leave it. Just make sure to uncheck the "Auto-Join" box next to any networks that aren't UWNet or EduRoam while on campus.
Go to System Preferences

You will see an extra option in the dropdown menu called "Open Wireless Diagnostics". Click this option.
