Ethernet not working until reboot T570



I've got a T570 with the most recent drivers installed through the Lenovo Companion and Lenovo System Update utilities. Sometimes after a prolonged time of operation if I undock the laptop and put it back on the dock the ethernet will not be detected until I do a full reboot. The same happens with the ethernet port on the laptop itself.

Is there a software issue that is preventing Windows from detecting the cable or am I missing something?


Model is a T570 with the i7-7600U processor and no LTE modem installed.





I've looked through device manager and whenever this problem occurs I see a whole bunch of WAN miniports under network devices. After a complete reboot these are gone. What could be causing them to come up in the first place?
