The latest kernels (at least in FC) are not using the latest ipw2200 
drivers.  If you want to try the latest, see 
www.ces.clemson.edu/linux/fc2-ipw2200.shtml.  These are mostly working 
very well for me.

ifup/ifdown *should* be dead-on reliable, if the config files are correct.

One thing I've noticed about NM is that sometimes after some 
suspend/resume cycles, I can't reconnect to any wireless network without 
toggling "enable wireless", restarting NM, and/or unloading/reloading the 
ipw2200 driver.  Otherwise, it's working well.
