How To get Wifi Adapter Working

Asked by vishal khialani

Hi,
I am trying to install a wireless usb adapter. I consider my self to be a basic linux user hence I apologize in advance if I make some mistakes.

Output of lsusb:

Bus 001 Device 009: ID 0cf3:9271 Atheros Communications, Inc.

I did a search on the net I found many articles on how to install it and finally I think the only one that works is installing a linux driver. I think I found the linux driver too at article at http://www.linuxwireless.org/en/users/Drivers/ath9k_htc

I need to advice on below:

1) Is my above understanding correct ?
2) How to install this driver and get it working ? / If there is a post which already has done this then it will be great.

Cheers,
Vishal

Please try this installation procedure instead:

Run the following 3 commands in a Terminal:

sudo aptitude update

sudo aptitude install linux-backports-modules-wireless-lucid-generic

sudo aptitude install linux-firmware linux-firmware-nonfree

Then reboot and follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep irmware ; dmesg | grep eth; dmesg | grep ath; dmesg | grep b43; dmesg | grep wl; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.
