I just went through this nightmare yesterday. There are a couple of critical things that people need to know. These are things that I encountered that took a while to figure out because they aren't obvious. Note that I use a customized combination of scripts to configure my wireless for different locations. I don't use any of the whizz-bang gui methods... 1) you cannot iwlist <interface> scan unless you bring the interface up first. You can bring the interface up without any parameters, do a scan, search the results and then process accordingly. 2) some of the iwconfig settings (particularly "mode" and maybe others) require the interface to be *down* before you can set them. So in my case where I scan for available access points and then set mode and ssid etc accordingly I have to up the interface, scan, down the interface, set some stuff, up the interface again to set more stuff and then pass it back to ifup to let it finish configuring the interface. It's kind of a pain, but it seems to work. 3) you need to delete previous references to your card from /etc/udev/rules.d/z25_persistent-net.rules file and let it be recreated. 4) it appears that WEP doesn't work for ad-hoc networks :( my .02 A
