Network Manager shows "never used"

English Network/Internet
1

My network manager shows under “Wired Ethernet” > “Wired Connection 1” and “never used”. This is clearly NOT my actual connection as I can connect to the Internet.

So my questions are (a) what is this connection, and (b) where is my actual connection (so I can configure it)

thanks

It’s not your network manager, but some funky applet. Run as root:

erlangen:~ # nmcli connection show
NAME                UUID                                  TYPE      DEVICE 
Wired connection 1  50aec290-a772-3efd-ba38-4074b80e9e93  ethernet  enp8s0 
lo                  fda9b66c-94fa-472f-8785-b19606e081e4  loopback  lo     
erlangen:~ #

Sometimes it’s handy to do this (as root)

nmcli -f NAME,TYPE,TIMESTAMP,TIMESTAMP-REAL connection show

or all this to see all fields

nmcli -f all connection show

Thank you all for these suggestions, but is there a guide as to how to USE this applet?

e.g. to quickly change IP Address, change between static or dynamic etc?

It seems like profiles can be created in the app using a particular interface - so is it a case of just creating a new profile and switching between them?

You never told us which applet.

It looks like a monitor in the system tray, when you open it it’s called “networks”. When you right click, “configure network connections”.

I presumed that is the only applet for network config!

Major desktop environments have their own applets (or whatever they are called in the respective DE), there is also GTK-based GUI that is often used by “lesser” DE. For GNOME the normal openSUSE documentation provides some starting points:

Using NetworkManager | Reference | openSUSE Leap 15.5

You may consider searching for something like “NetworkManager tutorial”, but those I have seen do not describe specific client-side GUI, rather provide examples using nmcli.

Mostly yes. Connection profiles are not inherently bound to any interface and NetworkManager tries to select the “best” connection profile on system startup. So, it is quite possible that NM does not select profile that you expect. Unless you constantly switch between different settings, it is easier to just have one connection profile and change it as needed.

I do, for configuring various equipment. But I think I get it now. Thanks for your help :slight_smile:
