Having it saved with a bad password may result in the user consistently getting on screen prompts that it cannot be joined. I just have a script that deletes the guest network if they are not currently on it that runs once a day. It has not solved the guest network woes, but it significantly reduces them.

@gquattro Not by using a network profile, but the approach I'd take if I really wanted to make sure someone didn't connect to a guest SSID would be to have a script that would check to see if the guest SSID was the active SSID, and delete it if so. I'd use a LaunchDaemon triggered by a network state change to run that script.

@sdagley @strayer

These are great ideas, do you guys know of a script that removes the guest network from the network drop down and the preferred wireless networks list all in one swing?

You can try something similar to what I do. See this post/thread for details https://www.jamf.com/jamf-nation/discussions/19092/remove-wireless-network-ssid#responseChild157523

@gquattro I made some minor changes to it, but I'm like 90% sure I started off with the script that @AVmcclint posted above.
