In my opinion, the only PEBKAC problem there is between the keyboard 
and chair of the person/people responsible for Network Manager. It is 
practically malware.

My experience with NM is that it is simply unreliable. It fights with 
the rest of the system (e.g. ifdown and ifup commands). I used to have 
NM running on my Debian laptop, and I frequently lost my network 
connection two or three times a week. Invariably, NM claimed the 
connection was up and everything was fine, and reconnection did nothing. 
Stopping and starting did nothing. Only a reboot fixed it, which is 
unforgiveable in my opinion.

Eventually, the sys admins at work badgered me into uninstalling NM. 
Since then, I've only lost the network connection a handful of times, 
and when it drops out,

sudo /etc/init.d/networking restart

fixes it immediately.

Somehow, NM has re-installed itself on my wife's PC, and since then she 
can't print to a network printer from some applications (while others 
work fine). Coincidence? I think not.
