This is becoming annoying. Not sure whether my recent experience is related to Win10 but I didn't have this problem while on Win8. SP3 connects to a Uverse modem via MS Dock. Several times a day I lose my network connection and the SP3 automatically switches to wireless which allows me to maintain access to the internet. Using the MS troubleshooting tool the SP3 elects to reset the Ethernet Adapter and I am back in business until it poops out again. Is this problem unique to me? Any advice to restore reliability?
