Hello to Everyone!

I have a really annoyng problem: i just bought a Z390 TUF Gaming Plus and a I5 9600k.
I had mounted all the stuff and install the S.O. (windows 10 pro), and then all the driver on the ASUS installation Cd.

Sadly, the system recognize the Ethernet Card (integrated) but report that the LAN cannot work properly due to "driver or hardware issues".

I had installed the ASUS updated LAN driver, the Intel LAN driver; I had reinstalled the O.S. and, then, reset the CMOS; all whitout any change: the LAN is still not working.

In the "device manager" panel, the ethernet device is recognized, but there is a Yellow triangle whit "!" simbole on it; i cannot connect to the internet (the system report that there isn't any connection).

I cannot undestand if it's an hardware malfunction or a driver conflict.

Can someone help me?

Thank you for your help (and sorry for my bad english!)

Marco
