This is great on Slaine...tried it with my wife's Netgear Wireless-N USB adapter (WN111v2) and worked very well with desktop and mini live-CD. Will there be updates to Taranis in the future that include functionality for the N cards?

Keep up the great work!

Coincidentally, I recently bought an Atheros wireless USB device for my new laptop, since the built-in wireless (a Realtek 8191SE device, if I recall correctly) either doesn't work with Free drivers or isn't recognised by Trisquel.

I thought that I was buying this: http://www.h-node.com/wifi/view/en/253/Atheros-Communications-Inc-TP-Link-TL-WN821N-v2--Atheros-AR9001U--2-NG-/1/1/undef/undef/yes/USB/undef

However, H-Node lists the device ID as 0cf3:1002 - the device I have is 0cf3:7015 and doesn't seem to work. This value is not listed in the usb.ids file, so perhaps it's too new to be recognised yet.

Both the Atheros USB device and the built-in Realtek card work with the Ubuntu 11.04 LiveCD, though neither of them work with the Debian 6.0 Stable LiveCD. I'm currently seeing what luck I have with Debian testing, since the problem might simply be that a newer version of Linux-Libre is required.

tl;dr version: There appear to be multiple devices with the name "Atheros Communications Inc TP-Link TL-WN821N" - some of them work with the current version of Trisquel and some don't.

After some investigation, it looks like the 0cf3:7015 device uses the Atheros AR7010 chipset.

http://wireless.kernel.org/en/users/Drivers/ath9k_htc#Firmware

Older firmware map:

AR9271 - ar9271.fw
AR7010 - ar7010.fw or ar7010_1_1.fw

Newer firmware map:

AR9271 - htc_9271.fw
AR7010 - htc_7010.fw

It looks like the the atheros-firmware package in Trisquel only includes the ar927*.fw file.

http://packages.trisquel.info/slaine-updates/all/atheros-firmware/filelist:

/lib/firmware/ar9170.fw
/usr/share/doc/atheros-firmware/changelog.Debian.gz
/usr/share/doc/atheros-firmware/copyright

Installing the Trisquel atheros-firmware package on Debian Wheezy causes a message to be shown during system boot, warning that ar7010_1_1.fw cannot be found.

Why is this? Is the ar7010.fw file not Free Software?

NOTE: The file is ar9170.fw on Trisquel, not ar9271.fw as stated on the kernel.org page.

He, what a coincidence.
Gobustu, you are telling my story.

I recently bought the same device:
the same investigations and the same question.

I'm really sorry it does not work.. anyway, can you please insert your device inside h-node marking it as not working and specifying also the chipset name inside the description entry? Is the model name given by the lsusb command the same as the one inserted inside h-node?

It seems that recognizing the device from the model name could be an issue sometimes

I haven't added the device to H-Node yet, since all I know is that it doesn't work without the 7010 firmware - the device works if the ar7010_1_1.fw file is put in /lib/firmware/ along with the ar9271.fw file.

Therefore, if the 7010 firmware file is Free Software, the device can be said to work with Trisquel (just not out-of-the-box, since you need to hunt down the missing firmware file yourself).

If the 7010 firmware file is not Free then the device does not work with Free Software.

Does anyone know what the status of the 7010 firmware file is, so that we can add the device to H-Node correctly?
