Hi,

I have a wifi extender, which I've configured, and I'm connecting to it by an ethernet cable.

Network manager wouldn't connect to it at all, it wasn't even trying to connect. I've managed to get the network working, by doing "sudo dhclient eno1" in a terminal - and it works. But network manager thinks I'm connected to a wifi network, with an essid when I hover over it for a tooltip - or not connected to any network at all, if I try to bring up the "connection information".

It would be nice to have network manger reflect the correct network information, although I'm a bit reluctant to change anything, because the network is actually working ok.

(It definitely isn't connecting by wifi - I've unplugged the wireless adaptor! ifconfig and iwconfig seem to show the correct information)

Has anyone seen this before?

Connections should have a priority (In KDE Settings -> Connections, this is under General Configuration). For me, I have Wi-fi preferred with priority 0 and wired connection at -100 because it is local to my desk. If you want to prefer ethernet I think you can set priorities accordingly.

What distribution? Are you still running Ubuntu. I have used wireless extenders in the same manner and I haven't had any problems. Is Network Manager configured to manage your ethernet port? Is it configured for DHCP that allows any user to connect?

Sorry, should have said - Ubuntu Jammy, XFCE with nm-applet on the panel.

Network manager seems to be configured correctly. But the panel applet thinks I'm on a wireless connection. Nmcli thinks I'm offline. Meanwhile, I'm actually online on a wired connection which is working fine!

Puzzling!

Ok I think it's just the panel applet that is showing the wrong info - for some reason it's showing the last network connection managed by network manager, instead of the current network manager information. Network manager has no record of the connection, I guess because dhclient is a lower-level tool and has created a connection that network manager can't see?

What about the output of
nmcli device

That could be. What happens if you reboot?

If you have something else besides NM managing your network connections there will be conflict, make sure your network devices are all down for NM to function.

Yes, nmcli device confirms it - NM isn't managing the interface. This box doesn't get rebooted often, but when it does I'll see what happens.
