LabQuest 2 has a rudimentary security feature meant to deter unwanted access to the connections settings. To regain full access to the connections settings do the following:
Tap Home / Preferences / Advanced Preferences / Network Tab
Tap "Connections app lockdown"
Tap Edit Preference
Change the Key Value to 0 to restore full access.
Tap on OK.
Other settings include:
0 = Full Access (default setting)
1 = Access to Network Settings Only
2 = No access to any settings
