[Techtalk] Basic connection questions

[Eeva Järvinen]

Don't know squat about .deb-based distros, but my experience of NM has been
that you really need to let it run the whole show, and after you've got it
running, then tweak the bits to more of your liking (say, making a
connection go up at boot instead of login). Configuring NM is best done,
IME, via the distro-given utilities.

NM is one ornery piece of kit but it's (probably) the only way these days
if you don't feel like tackling wpa-supplicant yourself. FWIW, my laptop
runs F18 with NM and starts the wlan at boot via rc.local - I couldn't make
NM do it all by itself with any reliability, probably due to systemd+nfs
conflicts (don't ask).
