This is the script I use when I need to kick the Network Manager after
it wedges up.  I probably have to use it about every day or two if I'm
wandering about travelling and hitting various access points that use
captive login portals or do something else funky.  It should work on
Debian/Ubuntu systems; you may need to change some pathnames to make
it work on other Linux distributions.

The bottom line is whether or not Network Manager works for you seems
to be mostly a function of which access points you happen to need to
connect into, and if you're travelling it's the worst case.

Occasionally something will get really screwed, and even the script
below won't work.  In practice I know that rebooting will fix the
problem, but so does killing NetworkManager entirely (use this script
with the 'stop' argument) and then manually using iwlist, iwconfig,
and running dhclient manually.  Since the latter is less disruptive
and rebooting, I'll usually fall back to the manual method.  This
usually only happens about once or twice a week while I'm travelling,
and it may be related to suspending and resuming a lot (since I tend
to do that often when I'm at a conference).

So I wouldnt call Network manager totally non-functional, I do have
relatively low expectations of it, and I do find that I need to use
the nm-reset script fairly often when I travel.  (This is using Ubuntu
Gutsy.)
