EDIT: For no apparent reason, I now have ethernet connectivity. I had to restart to computer for an update (I’d restarted it before with no success). A new wired connection seems to have been created. Can anyone enlighten me as to what has happened?
Original post:
I can no longer connect to ethernet
I’ve been connected to the internet via ethernet on my 2011 MacBook Pro. However, over the last few days, I can’t get it to connect, even though my wi-fi connection is fine. I did recently install Cloudflare 1.1.1.1, but I was able to connect via ethernet even after that. My Network manager (Manjaro xfce) only shows the veth8262db8 device to connect, not the wlp3s0b1 ethernet connection. Below is the output of the ip a command. Can anyone help me diagnose what’s going on? Thanks. I’ve looked at similar issues on this forum, but they’re not exactly the problem I’m experiencing.
