I've got my ipw2200 working in Fedora core3, not 100% sure what I did, was having problems. But i'm now posting from my Linux laptop and not from my windows desktop.

But i've had to turn off wpa-psk network authentication which is not good, I think. Where can I configuare this?

Ta.

I only know about one supplicant for WPA under Linux - wpa_supplicant (which is not to imply that there aren't others). What are you using for a supplicant? What specific errors are you getting when you try to authenticate?

I don't know, where do I configure it in Linux? I've had to turn it of in my gateway so that the laptop will connect. So I'm trying to find how to setup the laptop to use wpa-psk network authentication but I have no idea where to look.

I'm noob at this sort of stuff, windows has done it all for me in the past.

ta,

WPA involves two basic element:
encryption and access.

802.1x is the access component and that requires the use of a piece of client software known as a supplicant. The supplicant handles the authentication with the access point or RADIUS server to ensure that only someone with the correct credentials gets onto the wireless.

In WindowsXP, the supplicant is provided as part of (I think) SP1. There are also third-party supplicants by Meetinghouse and Funk for earlier Windows versions as well as XP.

Back to your situation. You need a supplicant in order to interact with the access point using the pre-shared key before you can "open the gate." http://hostap.epitest.fi/wpa_supplicant/ should do it.

Cool. Are there any detailed instructions on how to set up and use supplicant? Does it ride on top of the normal networking services ( those controlled in /etc/sysconfig/network-scripts/ifcfg-<device name> files )?

Thanks in advance.

It can be called from your ifcfg script. The wpa_supplicant README has a ton of info: http://hostap.epitest.fi/cgi-bin/vie...ype=text/plain

There are also some simple examples of the config file on the main page I lined earlier.
