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!

Check if your device is supported by the ath5k kernel module. Support for madwifi has been abandoned in favor or the ath5k driver, because the ath5k doesn't need firmware tainting the kernel. Unfortunately, some newer devices which were introduced after madwifi development stopped are not yet supported by the ath5k kernel module. Check madwifi and ath5k READMEs and FAQs to see if your model is supported. Look at "lspci -v" and "lspci -n" both. The manufacturer's code may be needed.

Search this site for "ath5k" and "madwifi"/. I seem to remember that there was an update about a new patch for either madwifi or ath5k.

Is this true? I have a strange ath5k problem in Slackware with the connection timing out - I would like to find out if that is a common issue.

If the device shows up, then you may have a supported device. You can check if madwifi or ath5k supports your device. Use "/sbin/lscpi -v" and "/sbin/lspci -n" to get information on your device. the "lspci -n" will provide the manufactures code.

Another thing that can be a problem is if internally your device is connected to usb instead of a mini pcmcia. Usb devices aren't supported.

I had connection problems on my new laptop (with an atheros wireless device) in Vista. My router is a linksys wireless n router. I found that disabling IPv6 fixed the connection problem.

If you run "wpa-cli" you can monitor the authentication process.
sudo /usr/sbin/wpa_cli -p /var/run/wpa_supplicant -i ath0
