But what? That I don't know. I suspect it is modprobing the driver. But here is a script I wrote to get my laptop onto my network when NM is being obstreperous: -------------------------------------------------- # Log in to curleynet # Time-stamp: <2007-03-27 06:05:47 root curleynet> # clean out the driver, in case it is hung up, and reinitialize the # hardware. rmmod ipw2200 modprobe ipw2200 killall dhclient # Detect the wireless interface, ignoring output to stderr. IF=$(iwconfig 2> /dev/null | grep ESSID | cut -d ' ' -f1) echo Interface is $IF iwconfig $IF essid curleynet nick dragon channel 6 key 12345678901234567890123456 mode managed dhclient $IF ifconfig $IF iwconfig $IF -------------------------------------------------- NM cannot be running while you use this. For normal, day to day use, I don't use NM on my home network. I leave the "network" "service" running and have that set up correctly (which took some work, but that's another issue). I have found that when I leave my own network for another, before I go, I: Start up NM: service NetworkManager start ; service NetworkManagerDispatcher start Wait for NM to acquire my network. Suspend or hibernate, as needed. On return I'll leave NM running until the next time I reboot or NM looses its marbles (not hard for it to do). http://www.charlescurley.com/Lenovo.R51.html -- Charles Curley /"\ ASCII Ribbon Campaign Looking for fine software \ / Respect for open standards and/or writing?
