Problem in Ethernet card after installing Zorin 16

Hardware Support
1

Hello,

I install Zorin OS 16 as my only OS in my computer and during the instillation it sees the Ethernet card and connecting to the internet

but after the installation is finished it couldn't connect to the network and it keep giving me an error message
"Connection failed
Activation of network connection failed"

I try to disable it and enable it but still didn't connect

so any clue to solve this problem

I'm facing with a fresh install of Zorin Pro, the same issue. I fixed this, with the following commands:

1 - service network-manager restart
2 - systemctl restart NetworkManager.service
3 - Restart the pc...

What is the device name of the ethernet card? For me, I generally try to find that out by checking the output of

sudo dmesg | grep eth0

Thank you for your replay

Unfortunately, I did what you wrote but the problem still exist

I did the command and this is the output

[    0.640933] r8169 0000:03:00.0 eth0: RTL8168g/8111g, a0:d3:c1:48:ed:67, XID 4c0, IRQ 31

[    0.641733] r8169 0000:03:00.0 eno1: renamed from eth0

I am seeing a common trend, here...

See if there is a link detected, and what the situation is with the auto negotiation maybe.

ethtool eno1

Well that seems okay on the basic link level.

I was having issues with my Realtek card which were solved by dowloading the driver from the Realtek website and running the install script.

That is probably worth a go too, and see if the driver supports your network card.
