I use my routers time blocking function to disable internet access on my kids PC at night time (PC connected via ethernet cable). 

The win10 network tray icon changes to show no internet access after the router blocks the internet,. 

But when the internet is reconnected,  the tray icon still shows that the internet as unavailable . A bunch of apps (eg, outlook) don't work because they say there is no internet, even though the internet is working just fine. 

I made a batch command to disable / enable the network interface, but this is manual. Does anyone have a more elegant solution or fix? Driver updates don't work, this seems to be a bug in win10 where the OS doesn't refresh the internet status on wired connections.
