The older method will become less and less supported as time goes on. Not that I'm a 'fan' of NetworkManager; I'm just a pragmatist in this regard: it's the preferred, supported, way to do things in that release, so might as well learn it, at least for those cases where it works well. It's not that hard to learn how to use nmcli to do both of those operations as listed above.

I needed to reactivate my Atheros radio after hibernate on CentOS 5.x,
and NetworkManager on 5.x was not able to do that,so I had to use
Network service and in cli to be able to script it.
I used NetworkManager in RHEL 6 Beta1 (recompiled it to work) but never
needed it in cli mode.
OP stated that he is *running* headless *server*, so extrapolation gave
me: CentOS 5.x (already running) and non movable system for one wireless
connection (headless server). So knowing how lame NetworkManager in 5.x
is, I suggested viable solution for his particular problem, unmovable
headless CentOS 5.x
And thanks for NM cli commands, I might need it when my laptop goes C6.
