TL-WN821N - Herman - 13th Jan, 2013 09:35 PM

I have a TL-WN821N dongle and I cant get it working.
Under dmesg I get:
"firmware not found"

lsmod gives

carl9170 77212 0
ath 17400 1 carl9170
mac80211 273484 1 carl9170
cfg80211 186124 3 ath,mac80211,carl9170

and ifconfig does not have wlan0 configured...
So does anybody know why xbian loads the module for the dongle?

It could be that we didn't include those firmware files. Does dmesg also state what firmware file you need?

Ok, no it does not. But that would explain alot why it don't work...

Can you check google what firmware file you need?

Hi again!
The firmware files where there, or at least I thougt. /lib/firmware/ar9170.fw so that seems to be OK.
But thats the old ones, so I downloaded the carl9170 firmware and voila! It works!

Can you tell us exactly what you did, and what files you used?

RE: TL-WN821N - Herman - 14th Jan, 2013 03:23 AM

cd /lib/firmware/


I used the wget command as stated in the page.

Then it worked.

I'm trying to add the same dongle wifi to xbian alpha 4 but it doesn't work for me.

I added the repository "deb wheezy main contrib non-free" in "/etc/apt/sources.list" and installed "firmware-linux-free".

Next I put the latest firmware carl9170-1.fw in "/lib/firmware"

The device is recognized with "lsusb"
Bus 001 Device 005: ID 0cf3:7015 Atheros Communications, Inc. TP-Link TL-WN821N v3 802.11n [Atheros AR7010+AR9287]

But I can't go further with the XBMC Network-Manager, please does anyone know what's my problem?

I also upgraded "firmware-atheros" but it's not better.

Some help would be very appreciate.

The XBMC network manager is bugged and will be replaced in alpha 5. Setup your wireless in xbian-config (will popup once you login via SSH) -> System -> Network.
