[Bug 1088809] Re: Atheros AR9271 not working on 11.10 and 12.04
Yitzchak Gale, as per
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel®+6+Series+Chipset+Boards&ProductProduct=Intel®+Desktop+Board+DH67BL
an update is available for your BIOS (0160). If you update to this, does
it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Thank you for your understanding.

Title:
Atheros AR9271 not working on 11.10 and 12.04
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
My TP-LINK TL-WN722N USB wireless adapter was working with Ubuntu
11.04. I upgraded to 11.10 and then to 12.04; the device does not work
with either of those Ubuntu releases.
As seen in the attached lsusb, this is an Atheros AR9271 device, with
vendor code 0CF3 and device code 9271.
The output of dmesg | grep ath is:
[ 15.018584] usb 3-2: ath9k_htc: Firmware htc_9271.fw requested
[ 15.018617] usbcore: registered new interface driver ath9k_htc
[ 15.809466] usb 3-2: ath9k_htc: Transferred FW: htc_9271.fw, size: 51272
[ 15.818943] usb 3-2: ath9k_htc: Unable to allocate URBs
[ 15.818999] usb 3-2: ath9k_htc: USB layer deinitialized
So as expected, no wlan device shows up in ifconfig. That also means
that this obviously is not an rfkill issue (though I did try that
anyway, just so that I can say that I did).
I verified (via sha1 and exact file size) that the firmware file
/lib/firmware/htc_9271.fw is indeed the latest available from
kernel.org. That firmware file has not changed for quite a while.
I downloaded the latest available version of compat-drivers, currently
2012-12-04, and recompiled the relevant kernel modules. Still the same
behavior, even after reboot.
I verified in the source code of the ath9k_htc driver that the vendor
and device code for this device are listed as a supported device.
