How to prioritize Pomona wireless in Ventura (MacOS 13)

In previous macOS versions from Monterey and prior, there used to be a preferred network list that you could edit in the Network -> Wi-Fi -> Advanced screen. Since Ventura has done away with System Preferences in favor of System Settings, that screen is no longer available. If both networks are in range at the same time, the list of preferred networks would determine which one would be chosen over the other.

NOTE:

Never use Claremont-Guest. This network is a very slow and limited network, meant only for guests of the college. Please use only Pomona wireless, and eduroam as a backup or if you travel to the other Claremont Colleges.

To removed (forget) Claremont-Guest from your computer, please use the instructions at https://support.apple.com/en-us/HT208941 . ITS also urges you to remove all unneeded wireless networks from the list to improve wireless performance.

How to prioritize Pomona wireless

Using the following command below in Terminal will list the preferred wireless networks. The topmost entry has precedence over the lower entries.

networksetup -listpreferredwirelessnetworks en0

An example of results will look something like:

Preferred networks on en0:
Pomona
eduroam
MySpectrumWiFiCA-5G
Starbucks

Ideally, Pomona wireless should be on top and eduroam second (if needed).

If that is not what you see, please use the following Terminal command sequence to set Pomona as the priority wireless network:

NOTE: If using a Mac desktop, you may need to use "en1" instead of "en0" in the following commands.

networksetup -removepreferredwirelessnetwork en0 Pomona
networksetup -removepreferredwirelessnetwork en0 eduroam

NOTE: Ignore this command if you do not use eduroam wireless.
networksetup -addpreferredwirelessnetworkatindex en0 eduroam 0 None

NOTE: Ignore this command if you do not use eduroam wireless.
networksetup -addpreferredwirelessnetworkatindex en0 Pomona 0 None

You can confirm the change using the networksetup -listpreferredwirelessnetworks command. The results should look like that in the example above.

Then, reboot your laptop to make sure the change held. Assuming you are on campus, your Mac should reconnect to Pomona wireless.
