Pc freezes when i try to activate my Lan-Port

Hey guys,
Yesterday I wanted to setup my wireless router and for that i deactivated my Lan-Port and activated my Wlan-Port. So far so good everything went fine, but when i wanted to switch back to Lan, i can't because as soon as i try to activae it, my Pc instantly freezes and won't stop until i force him to restart. The day before it all worked as it should.
I hope for quick responses (and sorry about my english)

System:
Main board: Gigabyte B150-HD3P
Cpu: Intel® Core™ i5-6600K
Windows 10 64-Bit

Has one tried rebooting the machine? Or completely turning it off for a few seconds?

Yap allready tried that noumerous times. I also kept the pc running for like 30min while he was frozen, but nothing changed.

Have you checked in Device Manager to check if anything is disabled or has problematic icons?

Thanks man! Tere was this little download-icon next to my ethernet connection. After the driver update it now works fine!

Glad it is sorted... that icon was probably showing as disabled.
