[solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

Hi all,

I have a TP-LINK TL-WN821N usb Wireless adapter which I am trying to get working via my recently done Arch system. Read the Wireless Setup @Wiki I have followed instructions to install wireless-compat (without problems) Having done the above I thought I could get this going! but not! smile I am hoping someone might be able to shed some light on this...? Thanks!!

So after the Wireless-compat install I rebooted but wlan0 and dmesg did not show anything useful with ath9k.

So I did :

modprobe ath9k

which showed me some good signs such as:

dmesg:

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

Is wlan0 in your INTERFACES=() in /etc/rc.conf or did you set up a profile for wlan0 using netcfg?

If not: you have to bring it up manually with
# ifconfig wlan0 up

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

Hi zenlord,

Yes, I did setup a single file under /etc/rc.network and configured /etc/rc.conf with:

NETWORK=(xfilename) 
DAEMONS=(syslog-ng hal netfs crond net-profiles network)

rc.network has:

CONNECTION="wireless"
DESCRIPTION="a simple open wireless connection"
INTERFACE="wlan0"
ESSID="XXXXX"
IP="dhcp"

if i do ifconfig wlan0 up output is:
wlan0: unknown interface: No such device

Hope having netcfg at startup is not causing a problem? Thanks

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

I don't know if it is related to your problem, but you should chose either 'net-profiles' or 'network'. Loading both could have unwanted collisions, but I doubt it is causing your problem.

Are you sure your device is named 'wlan0'? Atheros chipsets are sometimes named 'ath?', where ? is the number, probably '0'. Do your logs mention eth, ath, wlan?

Zl.

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

The driver for your Atheros USB stick is called ar9170usb not ath9k. However, the WN821N is not supported yet (using compat-wireless-2.6.30). You can try and apply this patch

Hi Zenlord, I haven't found any reference to ath0 using "dmesg | grep ath0" and doing "ifconfig ath0 up" gives "ath0: unkown interface: No such device" what are the other logs that I could check?

Tried disabling network and leaving net-profiles on but that did not do anything as you suspected.

Thanks thn81, however how do I run your code? (bit of a newbie i am afraid)
I have already make, install the package so its in my system. What steps should I follow?

By the way reading the code: what is meant by having path compat-wireless-2.6.30.orig/drivers.....  ? Am I supposed to change this in someway?

Thanks a lot!

1. Copy the contents of the "Code" box (starting with the "diff..." line) in my last post to a file and name it "wn821n.patch"
2. Get the compat-wireless-2.6.30.tar.bz2 package from wireless.kernel.org (you should already have it)
3. Open a terminal, unpack as described on http://wireless.kernel.org/en/users/Download, section "Building and installing"
4. Copy the wn821n.patch file into the compat-wireless-2.6.30 directory and change into that directory.
5. Use the following command: "patch -p1 < ./wn821n.patch" (without quotes)
6. Now continue with compiling and installing the driver just as you did before in your first try (make, sudo make install...)
Good luck.

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

Unfortunately that didn't work.
When I ran the code (as instructed) gave output :

bash-4.0# patch -p1 < ./wn821n.patch 
patching file drivers/net/wireless/ar9170/usb.c
patch unexpectedly ends in middle of line
Hunk #1 FAILED at 59.
1 out of 1 hunk FAILED -- saving rejects to file drivers/net/wireless/ar9170/usb.c.rej

then I still ran the make, make install, make unload and modprobe ath9k (also tried modprobe ar9170usb) but neither helped. I guess it just does not work with TL-WN821N.

I will try a few other distros to see if they might be able to pick it up(?)

Thanks!

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

Yes, you're right, sorry. Looks like the forum software here changed the format of the patch, so it doesn't match the original file anymore. (I think it replaced tabs with spaces...)
I uploaded the correct file to http://filebin.ca/kkwywc/wn821n.patch.
Sorry again for confusing you.

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

Apologies for the delay!
I tried the file that you had posted, thn81. It went through without error - and i continued to install compat-wireless. Rebooted the machine and did :

modeprobe ar9170usb

Dmesg gave me the following:

According to dmesg it seems the driver failed to register properly. Thats too bad I guess as it almost seemed to have worked.

Re: [solved - thn81] ath9k via wireless-compat but wlan0 is not coming up

Okay, we're getting closer...

usb 1-7: firmware: requesting ar9170-1.fw
usb 1-7: file with init values not found.

Looks like the driver needs a firmware file to work. It should be in /lib/firmware. Please read this http://linuxwireless.org/en/users/Drivers/ar9170 on how to get and to install it.
