      Go step by step by step and test.

     

     

    1. Power off the router. Unplug it from the wall. Wait a while.

        Plug it back to the wall. Power the router on. Wait until all lights are lit properly. It will take a while.

        Restart the computer.

     

        Start up in Safe Mode.

    2. Delete Caches.db

     

        Close all windows and quit all applications.

        Hold "option" key down and click "Go" menu in the Finder menu bar.

        Select "Library" from the dropdown.

     

        Library > Caches > com.apple.Safari > Caches.db

        Right click the Caches.db file and select "Move To Trash”.

        Close windows.

        Restart and relaunch Safari.
