View Full Version : [ubuntu] V9.04 & Atheros AR242x

April 24th, 2009, 05:43 PM
I am brand new to Ubuntu.
I have install V9.04 on Toshiba Satellite P105-S6147.
I am trying mightily to get WiFi operational.
I followed the directions in
& have gotten as far as below:

bcm@bcm-laptop:~$ sudo lshw -class network
[sudo] password for bcm:
description: Wireless interface
product: AR242x 802.11abg Wireless PCI Express Adapter
vendor: Atheros Communications Inc.
physical id: 0
bus info: pci@0000:03:00.0
logical name: wmaster0
version: 01
serial: 00:16:e3:aa:4e:d8
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress msix bus_master cap_list logical ethernet physical wireless
configuration: broadcast=yes driver=ath5k latency=0 module=ath5k multicast=yes wireless=IEEE 802.11bg

However I still see the following:

bcm@bcm-laptop:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11bg ESSID:""
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

pan0 no wireless extensions.

It appears I have made some progress but I don't know what to do next.
I am more than willing to RTFM, if somebody can point me at the correct FM which contains more clues.

Then I used http://ubuntuforums.org/showthread.php?t=202834&highlight=AR242x

sudo -s
echo 'blacklist ath_pci' >> /etc/modprobe.d/blacklist
apt-get install ndiswrapper*
wget ftp://ftp.work.acer-euro.com/notebook/aspire_4710/driver/Wireless_Atheros.zip
unzip Wireless*
cd Atheros
unzip HR*
ndiswrapper -i net5211.inf
echo 'ndiswrapper' >> /etc/modules
sudo init 6
sudo lshw -class network | less
sudo apt-get install wpasupplicant
iwlist scan
sudo gedit /etc/network/interfaces
sudo /etc/init.d/networking restart

The bottom URL provides examples for modifying the interfaces file

WiFi now works with V9.04 with Atheros AR242x WiFi interface
