Dell PRECISION 3640 Tower - cannot connect through ethernet

Hi all,

I am using a new PC Dell Precision 3640 Tower. I am able to connect to wireless networks, but when plugging in an ethernet cable it is not recognized. I checked different cables to exclude the possibility of being faulty but the problem persists. I also downloaded and installed an ethernet driver (Intel-PCIe-Ethernet-Controller-Driver_XX4J1_WIN_25.5.0.0_A20) but I still cannot connect to the internet.

Could anyone assist me?

Thank you in advance
