Exclamation Wireless Connectivity with Atheros ar242x in Hardy

Hey, guys. n00b here.

The problem: Atheros ar242x connectivity on a Compaq Presario C700 in Hardy. The connection is not being recognized at all. Other computers running Windows do not have any problem with this. This laptop also received a strong connection before installation of Ubuntu.

Outputs for...


uname -r:

Code:
2.6.24-19-generic
uname -m:
Code:
i686
/sbin/lspci:

Code:
bash: /sbin/lspci: No such file or directory
iwconfig:
Code:
lo        no wireless extensions.

eth0      no wireless extensions.
lspci | grep "Ethernet":

Code:
01:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
02:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
I've tried several variants of Madwifi and ndiswrapper, but nothing has solved the problem. Any help would be greatly appreciated. Thanks!

To get the PCI device information in Ubuntu, you don't put the path.
Code:
lspci -nn
The -nn will give the chip ID numbers. (post the output)

Did you modprobe to load the driver after installing it? If you have tried more than one driver, they could both be loading and conflicting with each other. Post the output of this command.
Code:
lsmod

I don't see any driver modules loading. Try to load the Linux module:
Code:
sudo modprobe ath_pci
If you don't get any errors, check the output of lsmod again for the ath_pci module.

Edit: Check the output of this command, I think that you may need firmware for the card
Code:
dmesg | grep firmware
Otherwise, download the latest driver snapshot from madwifi and follow these instructions for installing the madwifi driver:

For more info, I think that this is your wireless chipset:
