As far as I understand, the interfaces should be configured
automatically by networkmanager if you're using DHCP.  For wireless,
you'll probably have to enter a key if it uses encryption.

Shouldn't the file be named for the interface, like ifcfg-em1?

Networkmanager seems to have and to use its own configuration in
/etc/NetworkManager and may disagree with the ifcfg-* files, so if you
want to use networkmanager, you're better off using its configuration
tools rather than editing the files used by the network.service.

Networkmanager also messes with /etc/resolv.conf.  Just dropping an
ifcfg-* file into /etc/sysconfig/network-scripts or editing one isn't
sufficient because networkmanager doesn't understand from that what you
are trying to achieve.  And what about wpa_supplicant?
