Hi, i've never used a wired connection before, but I'm in a situation that requires a wired connection to a lab in class. The class is 5 days so I need to try and sort this as fast as possible so I can participate with the labs.
I have no problems connecting over wifi.
The arch wiki for my laptop (thinkpad x1 carbon) states that wireless and wired should work out the box.
Here is some output.

I have updated my kernel in a desperate hope that it would magically fix my issue, but no prevail.
uname -r

cat /etc/hosts

# See hosts(5) for details.
One thing to note is that I have no ethernet port, so I am using a eth-USB adapter.

I'm not sure what other information could be helpful. Thank you for ANY help, cheers.

How do you connect to networks?
Offline
I'm trying to connect by using an eth adapter to USB, and then selecting wired in the connection settings. The connection just tries to connect for ever
Offline
Why 2 NICs?
What hostnamectl says ?
What are you using to deal for the connection, wicd, NetworkManager, netctl, else ?
do it good first, it will be faster than do it twice the saint

Hi, I have no idea why I have two NCIS. This is the first time i have ever tried using the ethernet, I am using netctl

Ohh yeahj and the hostnamectl is
hostnamectl

If you're using netctl to manage your networking why are you trying to use the conflicting dhcpcd service as well?
Stick to one daemon only to manage your networking as stated in the wiki.
