Hi

I'm using Slackware 11 with 2.6.18 compiled kernel.

I installed a RT2500 PCMCIA Wireless card successfully. I also have an eth0 device. When I want to use ra0 device I have to define its IP, gateway...manually using route, iwconfig and ifconfig commands.
I found "Network Settings" module in the KDE Control Center, that is the tool i was looking for but when I try to modify the configuration of any device and save it the module gives me this error:

"There was an error changing the device's state. You will have to do it manually."

I run kcontrol looking for an useful error message and I found this:

QMetaObject::findSignal:KNetworkConfModule: Conflict with KCModule::changed(bool)
QMetaObject::findSignal:KNetworkConfModule: Conflict with KCModule::changed(bool)
--get XML:
<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<!DOCTYPE network []>

I try to reinstall Kdenetwork package, install KNetworkConf package but the problem still remains.
Ifconfig, route, iwconfig commands runs OK.

Any suggestions?
I hope you undestand me and my english, thanks!

Sounds like a software issue. Stick to setting your network settings automatically on startup with init scripts (ie, /etc/rc.d in Slackware). Or if you dont need it on startup, write a simple bash script (rc.wlan?) to bring up and shut down your wireless interface as needed. Chances are, the GUI you refer to is a front end for doing exactly what I described. Just do it yourself.
