Browsers freeze after wake-up or restart

[Helixal]

After I Start Windows 10 or wake up from sleep, browsers(edge, internet explorer, Firefox) hang. When I open the browser and click on a link nothing happens. To close the browser I have to use alt F4 or task manager. While this is happening, "service host local service(no network)(5)" is the most active application with 17-24% CPU usage. After about 20 minutes, the problem clears and the browser functions and the service host goes to 0% usage.  

Other apps which access the internet, such as outlook, quicken, malware bytes work, albeit more slowly. This behavior started in the last few weeks and before the latest win10 update.  

Any ideas about what's happening or how to fix the problem would be appreciated.
