Did a fresh install + updates of Kubuntu 8.10 on a customer’s laptop and had no wireless even though it’s an Atheros chipset.

Hardware:

• Laptop: Acer Aspire 4520
• Wireless Card: Atheros AR242x Communications Inc. 802.11abg

lspci | grep "Atheros"
07:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

Resolution:

sudo apt-get install linux-backports-modules-intrepid-generic

After above install completes, reboot, then open up the Hardware Drivers manager (jockey-gtk or jockey-kde) and disable “Support for Atheros 802.11 wireless LAN cards” and make sure that “Support for 5xxx series of Atheros 802.11 wireless LAN cards” is enabled then reboot. You may need to reboot to see both drivers in the Hardware Drivers manager.

This is at least a temporary fix, you’ll end up with the ath5k drivers- hopefully a stable universal method for Atheros card support will become available soon.

I’ve often resorted to loading up a Linux livecd and running “lspci” just to get an idea of what hardware is in a box. Let’s face it, even if box manufacturers do provide the drivers you need, that model may have shipped with one of 4 different NICs, video cards, etc. So it used to be I had to run a linux cd and the lspci command to get the PCI devices table but not anymore…

So when I first got my Black Asus Eee PC 4G xmas ‘07 I pretty much freaked out about all the possibilities but ended up installing my distro of choice, Arch Linux and all the Eee specific hardware support, then it kinda sat… and sat, until. I recently decided to review the current OS choices available for the Eee and settled on eeeXubuntu as the best candidate - clean little Ubuntu based with Eee hardware support out of the box. Besides, I just wanted to use my Eee not fiddle with the thing (I had my fill a few months ago, it was fun though).
