[SOLVED] Network Manager / nm-applet problems on fresh installation

I have just carried out a fresh re-installation of Arch on my old netbook, following a self-inflicted crash!

Previously, networking worked perfectly, but since the new installation, nm-applet is behaving strangely.

All connections (wired and wireless) seem to work OK, but when connected wirelessly, the nm-applet constantly shows the "searching" icon, and hovering over it, the message "Requesting a Wi-Fi network address for '<wlan name>'" is displayed. The Network Connections screen says that the Wi-Fi connections has never been used, despite the fact that it works!

I have tried re-configuring the connections, disabling IPV6 (this stops everything working) and completely uninstalling/re-installing Network Manager and nm-applet, but all without success.

I would be very grateful fo any ideas of how to tackle this problem

Many thanks in advance.

Re: [SOLVED] Network Manager / nm-applet problems on fresh installation

I'm not sure if this will help, but as of recently, nm-applet and networkmanager are somewhat independant, but rely on a common library - libnm.  The new networkmanager comes with a console interface called nmtui.  Does that work?  If so, you'd know the problem is with the applet.

Have you checked your logs

Re: [SOLVED] Network Manager / nm-applet problems on fresh installation

nmtui is giving the same result, so at least nm-applet is in the clear!

The logs (journalctl -b) seem to indicate some kind of problem with wpa_supplicant, so I will concentrate on investigating that further.

Many thanks for your help

Re: [SOLVED] Network Manager / nm-applet problems on fresh installation

I have fixed the wpa_supplicant problem (changed the .conf file), but the problem still persists. I have even carried out a full re-installation in case I did something stupid.

Nnmtui shows "connecting" permanently, and nm-applet shows  "Requesting a Wi-Fi network address for '<wlan name>'" with the cycling connecting icon.

Despite this, the wireless connection seems to work!

Can anyone suggest what else to try?

Disabling dhcpcd.service has solved the problem.

Thanks to everyone for your help.
