We currently deploy a WPA2 PSK via a configuration profile, we are finding a lot of client Macs are ending up with our client machine wifi at a lower priority than the guest wifi so suddenly nothing works and they get captive portal pop ups.



Can anyone help with a way to:




  1. Script the change of priority/index of a remembered wireless network?

  2. Reinstall a computer level config profile

  3. Script the addition of a wifi network without storing the PSK in plain text as part of a one line networksetup command?



Help would be greatly appreciated!



Thanks,
Christian

Hey @cdwyersg



You can use the following commmands to modify priorities of wifi. 



#!/bin/sh



currentUser=$(stat -f%Su /dev/console)

currentUserUID=$(dscl . read /Users/$currentUser UniqueID | awk {'print $2'})

wifi=$(/usr/sbin/networksetup -listallhardwareports | grep -A 1 Wi-Fi | grep Device | awk '{print $2}')

SSIDcheck=$(/usr/sbin/networksetup -listpreferredwirelessnetworks $wifi | grep $4 | awk {'print $1'})



echo "Wi-Fi on device port $wifi"

echo "Preferred wireless Network $SSIDcheck"

echo "Policy running for $currentUser"





#############################################################

######## Removes SSID from Preferred Wireless List #########

#############################################################



if [ "$SSIDcheck" = "$4" ];then

    echo "Removing $4 from Preferred Networks List"

    /usr/sbin/networksetup -removepreferredwirelessnetwork $wifi $4

    echo "Adding $4 to number 1 spot for Preferred Networks List"

    /usr/sbin/networksetup -addpreferredwirelessnetworkatindex $wifi $4 0 WPA2 $5

else

    echo "$4 not in Preferred Networks List, adding to number 1 spot"

    /usr/sbin/networksetup -addpreferredwirelessnetworkatindex $wifi $4 0 WPA2 $5   

fi

Pardon my ignorance on this, where do I replace the Wifi SSID we're trying to remove and/or the one we're trying to make top priority?

@jjones Had a good post here: https://jamfnation.jamfsoftware.com/discussion.html?id=17858

How about this exact same issue but on iOS???

@cruess If you need to stop a device from connecting to a network you could push out a profile to the device with the wireless login and password and then remove the profile and that should stop the device from connecting.

Can´t get any of the scripts to change the order of SSIDs I've found to work on Sierra.
Anybody have a script or trick that works?

I had good luck with this one at https://gist.github.com/pudquick/fcbdd3924ee230592ab4#file-reorder_wifi_alt-py-L5 after reading about it here
