Go to Network & Sharing, Change Adapter Settings and compare the wireless nic and the wired nic
I would also go to Windows update and review the latest updates installed. Check and see if there was not a Ethernet Driver update included. If there was do a rollback and reboot and try.
I had an instance a few months ago for a business application that was browser based that did not like an update to IE11, now I have my updates set to download but let me choose so I can review them first.
