Ethernet driver is not working with full speed

  • I am using OptiPlex 7040 - Mini Towe, that is supposedly using Dell Ethernet Connection (2) I219-LM

    That they say it should be a gigabit ethernet ..

    but the actual speed I am getting is 100 .. I don't know why and I don't know how to fix

  • I assume you checked all the elements of your network, right? Cables, switch, ...

    The best thanks to the help provided is to report what your solution was. The next one will thank you :thumbup:

  • No, half of my network is made with cat 5 cables, and I have a gigabit network with no problems. But the cables and connections must be in good condition. There cannot be anything on the network that is not gigabit.

  • @chente Thank you ...

    It was actually the cable .. changed it to cat 6 and now it is
