Ok, i'll do my best to describe this. I'm brand new to linux, but a M$ windows expert...

I'm using Fedora Core 6 (KDE desktop), and have installed wifi radar and kwifimanager. I can't get my wireless card to work at all -- and i don't think its even enabling -- it shows as inactive in network device control, and when i try to activate, I get this:

Error for wireless request "Set Mode" (8B06) :
SET failed on device eth1 ; Operation not supported.
Error for wireless request "Set Frequency" (8B04) :
SET failed on device eth1 ; Device or resource busy.

Determining IP information for eth1... failed; no link present. Check cable?

The computer sees the wireless card as a Intersil Corporation Prism 2.5 Wavlan Chipset. I'm using a Compaq Presario 2525US.

I've tried to install the ndiswrapper, but that fails:

Error Summary

I've tried searching everywhere, can't find much... I know this is probably something simple, but i would greatly appreciate some help!

Please be very specific if you try to tell me how to do something. Like -- start with "open terminal" . I'm that new.

Thanks!

Hi,
I also had alot of problems gettings ndiswrapper to work.
It is best to build it from source.

First look if your wlan card is supported by ndiswrapper.
BTW: Wifi radar and kwifimanager are just program to have a graphical UI. I never use those GUI's anymore.

thanks. major update. I am now using a D-link DWL-G650 PC card adaptor, i gave up on the built-in. after tons of research and trying, I have successfully connected to my WPA wireless network. yes!

NOW, my issue is: After rebooting, I have to run this command -- and then go to the network device control and click ACTIVATE on the wireless card
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd

any way to get it to this automatically on startup?

you can create an rc script (put in /etc/init.d).
Put the command in a file and make it executable (chmod 700 thefile).

You can also run this file as startup.
I think you can put it in /etc/profile.

But I am not shure at all about the /etc/profile.
So maybe someone check this.
