Q: Internet Access VERY SLOW at Startup

After starting computer, access to internet is nonexistent or extremely slow.  Some of my apps will connect immediately, but using either browsers I have, be it Safari or Firefox, I cannot access the internet for up to 10 minutes.  Something on my Mac is blocking access to the internet until it decides to allow it!   Any ideas??

Mac Pro (Late 2013), OS X El Capitan (10.11.6)

      Go 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.

     

    3. Empty Caches

        Safari > Preference > Advanced

        Checkmark the box beside "Show Develop menu in menu bar".

        Develop menu will appear in the Safari menu bar.

        Click Develop and select "Empty Caches" from the dropdown.

        If this doesn’t help, please run EtreCheck and post the report here.
