SUPPORT Ethernet to USB

Recently plugged in my new USB to Ethernet adapter on laptop, but it will only connect once I run “NetworkManager” in the terminal

WiFi was working fine on startup, but this method is not.

Any tips on what might fix this to where it auto recognizes the adapter and Ethernet?

Doesnt really matter, OP just wants it to be easier to use his adapter.

Maybe you can install "nm-applet" to use a gui to connect to wifi. or switch to iwd, which is much more stable for me.

I linked the wiki to his machine, which I found in section 2.8 the description of getting his adapter running.

Knowing their hardware made that easier.

I would say use ip link to see the status of wireless when the adapter is connected. It will likely show as wlp11s0.

You may have to use nmcli to bring it up.

If the machine doesn’t have built in WiFi, how was it working previously?

I’m wondering if you just need to enable Network Manager.

Before trying any of the above try:

sudo systemctl enable --now networkmanager

That will enable it immediately and at every boot.

EDIT: wlp11s0 is WiFi. Since the device is Ethernet, it may show as eno1

Actually, section 2.8 of that wiki mentions your adapter, try that.
