Managing Wifi Connection With Intel 3945

I have no problem using wireless at home with the Intel 3945 wifi card on my Dell 1420n, with Network Manager. I have no trouble with either the ipw3945 or iwlwifi drivers or switching between them (switching requires minor change to udev rule file). But this method is annoying, especially if I want to go to a cafe with free wifi, since I have to open up yast and change DNS settings to dhcp (I use static at home), and this doesn't even always work so well. I installed wifi-radar and kwlan (through yast) and changed yast network device setting to use ifup instead of network manager. But I cannot seem to get either of these two to work with my WPA enabled router at home. With wifi-radar running in the terminal, I get the following output:

Error for wireless request "Set Frequency" (8B04) :
SET failed on device eth1 ; Invalid argument.[/b]

and kwlan gives me an error message that says:

kwlan was unable to start wpa supplicant[/b]

I do have wpa_supplicant installed. Has anyone had success with this wireless card and wifi-radar on 10.3? For the brief period I had Ubuntu installed on this thing when I first received it, I used a wonderful program called wicd, which worked perfectly for this sort of thing. It offers source, but I have read that it's coded very Ubuntu-specifically. Has anyone managed to install on 10.3?

Hi
I'm not able to help about the wifi configuration but I use SCPM (System Configuration Profile Management) to manage different network configuration

Thanks for the tip. I will try out SCPM and see how it goes. I didn't know what SCPM was for. It does seem like a needlessly complicated way to do this, however.

SCPM has a command line and a windows interface to switch from one profile to the others.
A profile is a set of configuration files of your machine from the xorg.conf to the network configuration file.
You can copy, rename etc.. the profile you defined.
I use the command line to switch from one profile to another using

scpm switch profilename

Thanks for the suggestion of SCPM. I set it up finally and had a chance to try it at a cafe. Switching works perfectly. Except for having to close and re-start Network Manager, it works perfectly and saves a lot of time. This will work until either Network Manager gets more functionality or other tools like wifi-radar work better with the Intel 3945.

Infact I don't use Network Manager I use the standard "ifup" method, in this way running the scpm command it's all I need. Happy to be helpfull.
