Linux Mint Cinnamon

[209Guy]

I've booted both Mint 20 and 19.3 and I don't have any ethernet connection.  Has anyone had this problem before? I've seen in other places that it's the 5.40 kernel and I need to upgrade to the 5.7.

What is the output of running

ip a

in a terminal?

I had the problem of no wifi (ethernet worked, though) on 19.3. Had to download a driver from some dude in github. 20.4 has been kinder.

 

To be clear, you have no connection or you don't see the interface as existing?

Most often in debian derivatives I find the issue is the adapter name (found in the `ip` command given earlier) doesn't match what's configured in `/etc/network/interfaces`

I just don't have connection.  I see the adapter. It says that it's trying to connect, but doesn't.

When i type this command, i get this.

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Have you attempted to turn it on manually?

sudo ip link set enp7s0 up

Yeah, that doesn't do anything for me.  The "tab" is switched to on/connect, but it just won't connect. I might give up until Mint gets a fix in. I don't care much for any other flavor of Linux.

Did you check to make sure the device is using the correct driver? You can use lshw to check.

lshw -c network
or
lshw -c network | grep driver

 

If you grab the device bus info from lshw you can search dmesg for possible errors. In my case my ethernet controller is on 00:19.0 but use yours in the command.

 

dmesg | grep 00:19.0
