LinuxQuestions.org - Wireless with WPA

It seems WPA is giving many people alot of troubl to install, I'm one of them. I'm all new to linux but I want to get the wirless security running and it's honestly killing my experience of linux. :(

I'm running Ubuntu and if I have the router set to open it works fine. The card is recognized at once and I can connect through it. However, if I set the router to WPA (have widows comps using it so I know it's working) and then try to use wpa_supplicant nothing works as it should.

I have tried several guides as well ass chats where I have gotten lots of help but everything has failed so far.

I might be way off, correct me if I am and let me know where to begin, but these are the things I suspect;

1. The card uses orinoco_cs, however this is not supported by wpa_supplicant?
2. The orinoco_cs driver, though operational, is wrong for my type of card. I've fund that my chipset it most likely Prism3.

Quote:

FCCID PKW-WPC11-V31 (approved 7/23/2002) uses ISL3871xxx or Prism3

Another page stated Prism2. cardctl gives procduct info: "The Linksys group, Icn.", "Instant wireless network PC CArd", "ISL37300P", "RevA"
3. I need to use ndiswrapper to get it working, however I can't findt he correct drivers. The windows XP drivers from linksys keeps showing up as Invalid driver.
4. my configuration is completly wrong.
5. Something else

As an addition i want to mention that the card (linksys WPC11 ver3) didn't have WPA support when it came out, linksys has released a driver for it since then.

(eth1 is the wirless card)
Here are my current files

Quote:

/etc/network/interfaces

auto eth0

pre-up iconfig eth1 up

Please help me, I'm about to give up on all this soon and i really want to use linux, not trash it!
