Maybe this was it? https://www.jamf.com/jamf-nation/discussions/20271/wifi-ssid-prioritization

@chris.hansen That isn't it unfortunately. I had a copy on my machine somewhere but it's nowhere to be found. I went through a ton of posts on here relating to wifi and couldn't find anything.

This is relevant to my interests. I keep looking around for something like this but do not have the chops to create it myself. I have found a script that blocks access to a set of networks. https://www.jamf.com/jamf-nation/discussions/5327/need-help-with-wifi-script This might help you get to where you want as you can put the teacher networks in a deny. But I need one that will force a connect to my main network over the others.

I do have that script but it's a little invasive. The kids here will go day without coming to us to get back on the network (need admin to turn airport back on). That's why I was looking for that particular script. It just switched them back to their particular network.

Bit of an old thread but does this script still work?
