View Full Version : [ubuntu] Acer AOA150-1635, AR242x, Ubuntu 9.04: wireless not working

July 8th, 2009, 08:52 PM
I've set up the Acer Netbook to dual boot XP and Ubuntu 9.04. The wireless works fine with XP, but isn't recognized with Linux. I've tried some of the suggestions in the posts on the AR242x with no success. I'm not sure what to do next.

03:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
Subsystem: Foxconn International, Inc. Device e008
Flags: fast devsel, IRQ 18
Memory at 55200000 (64-bit, non-prefetchable) [size=64K]
Capabilities: <access denied>
Kernel modules: ath5k, ath_pci

deh@Acer150:/$ lsb_release -d
Description: Ubuntu 9.04

deh@Acer150:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

pan0 no wireless extensions.

If I go into System/Administration/Hardware Drivers I get the following, and it is shown as active and in use--

Alternate "madwifi" driver for Atheros wireless LAN cards.

Only activate this driver if you have problems with your wireless LAN connection.

The free "ath5k" driver should work with most Atheros cards nowadays, but on some computers this alternate (but proprietary) driver still works better, or at all.

The "DISABLED" suggests something needs to be enabled, but I don't what that might be.

I got it working by following the procedure in the following thread--


I found that the worked fine with Suse 11.1 with the ath5k driver, so it should work with Ubuntu and the ath5k driver.
