Ready, i try to follow the instructions but,
For example with the command for disable the autonegotiation:
sudo ethtool -A enp7s0 autoneg off
I get the following error:
Cannot get device pause settings: Operation not supported
standard information about device
Settings for enp7s0:

The usual troubleshooting steps here are:
1) Replace the Ethernet cable.
2) Install ethtool, use it to disable autonegotiation, and try setting
the speed and duplex by hand.
Failing that, replacing network card produced by Dell with something more
proper is always an option.
