wpa support in ubuntu with aironet 350

ok, first off, I'm very new to linux, so please be patient. From what i can gather, wireless networks are not the easiest things to get working in linux.

My wireless Cisco aironet 350 PCMCIA card was picked up and working when i installed the dapper drake version of ubuntu. And it seems to work fine with either no encryption or WEP. But i need and adapter to work with WPA as this is the encryption protocol that the rest of my house use. I've tried installing network-manager-gnome to manage all the whole process for me, but although it shows that the network is there, it doesn't come up with the option of entering a wpa psk to access the network. It just gives the options of wep 64 128, or no encryption at all.

so then i gave up on managers. I was also messing around with wpa_supplicant for a while and that complains that although it can see the network the driver doesn't support WPA encryption. So i was looking around to see if the cisco aironet 350 does support wpa. I saw somewhere on a forum (i can't remember where now) that there was a mention about updating ur firmware to enable wpa support, but it was just a mention and didn't explain or link anywhere. And by looking at a few cisco readmes, they never mention wpa.

So does anyone now whether there is a way to get wpa to work on the cisco aironet 350? And if not, I do have other wireless cards. There's a wireless network card on board, but it doesn't have great reception hence the use of a pcmcia card, and i'm not sure what it is (i can't find it on the device list) although again it is installed and working with no encryption or wep. Is there a command to show what hardware is installed?
But anyway, again that card (whatever it is) when run with wpa_supplicant, says: "driver does not support wpa". Note that i have never actually tried running these two wireless adapters in windows and don't have the means to do so, so i don't know whether they support wpa or not.

If neither of these do work with wpa, i also have a usb network adapter Belkin F5D7050 that i know works with wpa in windows that i have not attempted to install yet.

Please help me.... I don't want to have to adjust everyone elses wireless networks just to get my laptop working on the network.

ok, i now have installed fairly experimental drivers from which are supposed to add wpa support to the standard drivers. It looks slightly more promising. I can now get wpa_supplicant to recognise the network i want and attempt to connect to it, when i run the command
sudo wpa_supplicant -Dwext -iwifi0 -c/etc/wpa_supplicant_wpa -PSK.conf -d
but gives out the error
WEXT auth param 8 value 0x0 - Association request to the driver failed
and then can no longer see the network when carrying on, and when it finishes i can no longer see the network using
sudo iwlist scan
Anybody have any idea what this means. Is this a failure of the driver or is it something to do with how i've set up wpa_supplicant? Once i've run wpa_supplicant the driver then kind of shuts down. I can't then do anything with it until i've restarted the computer. I would greatly appreciate any help.

sidenote: i mentioned before that i have two wireless network cards installed. This isn't true. It was just something to do with how the airo driver sets up the wireless card. It creates two almost identical interfaces for it. so both eth1 and wifi0 refer to the same device.

I am having a similar issue "Association request to the driver failed". But I took a different route. I am using ndiswrapper with the windows driver and a custom build of wpa_supplicant and other utilities. However, this is the same error that I get :-( Any luck with WPA on the 350 in Linux? Anyone at all? If Windows can do it, ndiswrapper should be able to I would think...

I gave up on the 350. When i did use it I just ran with WEP and MAC filtering.
Rest of the house was adjusted accordingly. Was secure enough for my needs.
