Atheros 9170 won't work after Kernel update

Postby foxhunter on Tue Jan 10, 2012 4:30 pm

Hi all,

i'm using the Debian version of Linux Mint 12. Installation went fine,

I am having two wireless cards in my HP laptop. The internal one is a BCM43sx device, which is usually not in use.
The other one is an Atheros 9170 USB Stick. I've switched to this, because the BCM doesn't support 802.11n which is necessary for my broadband connection.
With the default installation the stick is working fine. But after an update and reboot to Kernel 3.0.x, the Adapter stopped working.
There is no trace about it's existence in iwconfig or network-manager. The only information is coming from lsusb:

Code: Select all
Bus 001 Device 004: ID 0cf3:1002 Atheros Communications, Inc. TP-Link TL-WN821N v2 802.11n [Atheros AR9170]


I'm currently running Kernel 2.6.39 to get the Atheros stick working.

Any ideas?

Greetings

Linux Mint is funded by ads and donations.

ar9170usb is no longer used as of Kernel 3.0. You need to replace it with carl9170.

Grab the firmware from here:http://wireless.kernel.org/en/users/Drivers/carl9170/fw1.9.2?action=AttachFile&do=get&target=carl9170-1.fw

Place it in /usr/lib/firmware

Blacklist ar9170usb
Code: Select all
echo "ar9170usb" > /etc/modprobe.d/blacklist.conf


remove ar9170usb module
Code: Select all
modprobe -rv ar9170usb
depmod -a
modprobe -v carl9170

Thanks for that useless posting. I've used the board search.

Thanks, but how has it to be done? I've used Linux a couple of years before but i did not have to change drivers so far.
