Missing the ethernet interface in KDE plasma

Support Network

Hi,

I have a KDE plasma OS.
When I check the network interface of my machine I only see the loopback interface and unable to see the ethernet interface. Kindly help me to fix this

@pobrn, kindly find the outout, do you need the entire output of lspci -k ?

The network and ethernet controllers are relevant now.

That output does not show any ethernet controllers. Is the device a PCI or USB ethernet controller?

I cannot see any ethernet interface in my output, all i could see only the wireless adapter and other controllers

What’s the output of lsusb?

@pobrn

Seems the command not available in the console.

lsusbm 130 ↵
zsh: command not found: lsusbm

I made a typo in the command, it’s fixed now, please try again.
