I follow these steps
https://wiki.archlinux.org/index.php/Ne … anager#KDE
I've installed nothing to my network. I got connection at instalation time.... I use dhcp
Network manager works, by a half. disabling net on it, turns off the internet, also reenabling turns it on, but still appears "don't connected"
I need Network Manager cause I'm folding at home contributing and, sometimes, my internet comes slow, so slow, and restarting it solves. In the "rc.conf times" a "/etc/rc.d/network restart" was enough, but with systemd I don't know the correct command, and with network manager just disable networking and reenable it
I think that may be it's the interface name (enp7s0) I've not changed it to promiscous mode.
I am not sure if I understood everything, but did you enable the DHCP service ?
If you enabled the DCHP service, then you need to disable it with :
systemctl stop dhcpcd@enp7s0 systemctl disable dhcpcd@enp7s0
Take a look at this for full instructions:

Also, please post the EXACT error message, I am pretty sure, there is no error messge as 'dont connected' in KDE.
