Wired Connection Failed

I’m trying to connect with an ethernet connection, and I’m using an ethernet to usbc connector. I get the error below

I’m currently on nixos 22.05.4328.68ba2f40991 (Quokka). I’ve tried systemctl restart NetworkManager, I’ve also rebooted my machine but I still get the same error. Any assistance is greatly appreciated. Thanks :pray:

There’s not much info here to go off of. What is the model of the device and how are you managing it (via your Nix configuration or do you use Gnome, etc.)? Any other relevant logs in journalctl?

Thanks for the response! It turns out my modem was misconfigured and the ISP had to replace it. I was doubting that it was just my nixos machine so I started trying it out with my other devices and my windows machine said “Ethernet doesn’t have a valid IP configuration”.
