I have a RaspBerry PI 2B running Windows IoT Core connected via an ethernet cable to the internet. Sometimes, and mostly after a reboot/power outage, it isn't able to connect with the internet. Without an internet connection the PI becomes useless to me because I'm not able to ping it, remote-control it (with PowerShell), ...
Now when I extract the SD card, burn a fresh image back on it and insert it into the PI the ethernet connection works again.
Anyone has an idea on what is causing this?
