Titanium Backup stuck during backup On my phone, a OnePlus 3 running Marshmallow, I have Titanium Backup configured to run automatic backups twice a week. When it runs, it gets stuck. The notification displays "Skipping   96% - Wi-Fi access points." This notification sticks around until I force quit Titanium Backup or reboot the phone, and I presume that the backup never completes.

Google searches have revealed nothing that appears relevant. Any ideas what's wrong?
You need to create a filter to exclude the 2 WiFi Access Points.
In Titanium Backup, Goto Menu > Filters (under General) > Create Label (At the bottom right) > Add/Remove elements > Select all and then Uncheck the 2 WiFi Access Points at the bottom of list and Save (check mark at top right) 
Click Load/Save filter to save it as a filter
In scheduled backups, edit and select the Filter name and save
