There is a user preference in LabQuest 2 to deter student access to naming, network, and connections settings. This is not a true lockout. It simply removes the gear icons where access is normally found. It is simple to set up as there are no passwords; however, anyone can change the settings back to default.
From Advanced Preferences (Home > Preferences > Advanced Preferences), go to the Network tab. Tap on Connections app lockdown.
Lockdown mode has three settings:
0 - Full access to all settings
1 - Access to network settings only
2 - No access to any settings
Tap the Edit Preference button, choose the level of lockdown preferred, then tap OK.
To re-enable the gear icons, see:
