Wpa_supplicant in /etc/network/interfaces and Karmic Koala 9.10

Most of you know that Karmic Koala 9.10 released on the 29th October.  I noticed during my test run with Alpha’s and Beta’s of Karmic that my use of wpa_supplicant as described in this article didn’t work any more.

The lines in /etc/network/interfaces have changed from:

wpa-conf /etc/wpa_supplicant.conf
wpa-driver wext

to:

pre-up wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B
post-down killall -q wpa_supplicant

Also if you where using :

wpa_supplicant -Dndiswrapper -iwlan0 -c/etc/wpa_supplicant.conf -B

then this now has to be changed to:

How To Get Atheros AR242x To Work on 8.10 Intrepid Ibex

Updates

**02-24-2009** Instructions for fix after update to kernel 2.6.27-11-generic below.  This how to uses compat-wireless-2009-02-24.tar.bz2. It was tested on (K)Ubuntu 8.10 KDE 4.1.2. Kernel version 2.6.27-7-generic & 2.6.27-9-generic

For instructions on getting the AR242x to work on 8.04 click here.

Introduction

You could see this as part 3 in the series: How To Get Atheros AR242x Wireless To Work
It’s with disappointment that I have to report the following:

I started with a fresh install of Kubuntu 8.10, the reason for this is simple I wanted to make sure that nobody could say “you should have done a clean install”. On a clean install out of the box the AR242x doesn’t work.

What I Tried First

So I started to search for solutions. There a several solutions out there here is a quick list:

The last option worked the best for me so that is what I’ll go with for this how to. Let me clarify that ath_hal, ath5k and ath9k are all developed by madwifi so props to them for doing such a great job of developing the drivers that make wireless for the AR242x work under Linux.

AR242x The saga continues

Some good news for AR424x users. Intrepid Ibex the new version of (K)Ubuntu will support the AR242x natively. This means non of the work a rounds are necessary any more. At least we hope that they will not be.

This is a revision of my original post using the solution provided by Madwifi it’s been tested by me and it works.

Windows drivers are here

If you own the same laptop as I do, a Toshiba A205-S5825, then you probably have the same problem, if you are using Hardy or Gutsy with the newest Kernel(2.6.24-19-generic) or older, the wireless doesn’t work out of the box.

It cost me about an hour to solve this mainly because no one knew anything about this particular chipset.

So here is the solution for the AR242x. If you have a chipset in the A5700 series then this could work for you too.

The solution is quite simple and only takes you a couple of minutes to apply and then you can use your wireless.

For this How to you do need wired internet to the computer.
