Hello community! 

I just acquired a new U2723QE which just arrived today. Now I found out, that my RJ45 port is not working (laptop without LAN connection - the network cable is functional however!). 

Tried to check for an updated firmware, however, I did not find anything on the Dell website. My firmware version is M2T101. 

Is there some recommendation on what I can do to enable my LAN port?

Thanks for your help!
