atheros 802.11 wireless LAN card problems

I had exactly the same problem. Here's what to do:

1)Make sure you are connected to the internet
2)Open Synaptic Package Manager in System>Administration. Enter your password.
3)Search for the package linux-backports-modules-interpid.
4)Once you find it, double click it.
5)If Ubuntu asks you to install some more packages, accept it.
6)Click Apply Changes. Ubuntu will ask you to confirm.
7)After installing, go to System>Administration>Hardware Drivers. Wait a little. You should see two atheros-related items in the list, one enabled and one disabled. Enable the disabled one and diasble the enabled one.

At this point do a restart. If your laptop has a wireless switch, make sure that it is on before Ubuntu starts. Before connecting, you have to go to System>Administration>Hardware Drivers and make sure that the newly installed dirver is enabled. If not, enable it by hand.

i have done it.
but the wireless switch cannot be on.
need help..

Click on the Network Manager icon (the one on the top-left with the two side-by-side computers). Do you see something like Wireless Networks and a list of networks? Also, could you tell me wihch drivers are listed in Harware Drivers and if they are enabled or disabled? Maybe you could disable and re-enable the newly installed driver and then try to connect.

Hi,

Please follow this procedure:

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

Step 2: Run the following commands (type each then hit <enter>)

sudo iwlist scanning
nm-tool
iwconfig
ifconfig
sudo lshw -C network
lspci
lsusb
uname -a
dmesg|grep ound
dmesg|grep etect

Step 3: Post results (cut/paste terminal output from each command) here

Regards,

Mark

Mark Rijckenberg,
i`ve done like you said.
and this is the result.

Hi,

First add the following lines to /etc/modprobe.d/blacklist

blacklist ath5k_pci
blacklist ath5k

Then follow the instructions from forumuser "reasoner" at this
