Re: Fwd: Having a hard time with NetworkManager on ArchLinux

Ok, some good news.  I'm now typing this e-mail on my laptop through my wireless!

I rebooted my machine and then proceeded to re-connect using NetworkManager and got a connection.  I don't know exactly why, but I'm inclined to believe that it has to do with the fact that I removed some previously set state (perhaps having dhcpcd release the wlp3s0 resource after rebooting?) and had NM do the setup that it needed to do.

If you are using NetworkManager (or wicd, ConnMan, ...), you don't
manually use ip, dhclient, ... (unless you have a good reason to).

Usually, NetworkManager (the deamon) starts at boot time, as you enabled
it with systemctl. What you click on, is a GUI front-end, to tell
NetworkManger what to do. Probably it's nm-applet (Gnome3 and KDE
usually come with different ones).

You should check, that the WiFi connection you are trying to connect is
properly configured. You can right-click on the icon of nm-applet and do
"Edit connections".

If you cannot figure out whats wrong, it might be helpful to look at the
logfiles and provide more information

  journalctl -b 0 _SYSTEMD_UNIT=NetworkManager.service

Sure, that sounds doable :)
