[Diego Cananéa]

Hi,

my name is Diego and I'm a Master Student. My research is about Available
Bandwidth Tools on 802.11n networks, the influence of MAC layer.

I want to work with TP-Link TLWN822N USB Adapter, which use Atheros Chipset
and Ath9k_htc driver. But I don't know how I can enable and disable MAC
layer paramaters like:

- AMPDU
- AMSD
- BlockACK

I look at https://github.com/qca/open-ath9k-htc-firmware for this option,
but I don't see how can do this.

Thanks!

Looks like in new kernel. There are no fixed_rate_idx and mac80211 subdirectory.

Hi Bruno,

Thanks for your quick reply.

In STA we are using ath9k (mac80211) driver and in AP we are
using propriety driver from atheros Fusion (same flavor as madwifi). it has
wds option enabled already.

You are right 4 address mode should work with this implementation but as
wds is not standard so i think its implementation is different with
different drivers. Ca you please confirm if anybody has faced same issue as
ours and if yes what have they done to correct it.
can you check with this link
http://wireless.kernel.org/en/users/Documentation/iw. Here they have
written that 4 address mode is incompatible with WDS.

Thanks
Aman Sharma

Hi Sujith,

yes, we are using non-mac80211 driver in "*atheros"(AP mode)*.

In STA mode, We are enabling 4 address mode using command  *iw dev wlan0
set 4addr on.*

And in AP mode, we are not enabling or disabling WDS.

Thanks for your help.

By "atheros" do you mean a non-mac80211 driver ? WDS requires the same implementation
on both the root/client APs. See: http://wiki.openwrt.org/doc/howto/clientmode

Hey Bruno,

One more thing:

Laptop1 -------(AP)      -------     (STA)-------Laptop2
                 atheros              ath9k

If the STA interface is not in bridge then Laptop2 is able to get Ip from
AP but if the STA interface is in Bridge using 4 address mode then its not
able to take Ip from AP. I think its due to the 4 address compatibility
issue.

Please suggest Something for this.


Thanks

Hey Bruno,

What's the contents of /etc/config/network of STA?

ls /etc/network
if-down.d  if-post-down.d  if-pre-up.d  if-up.d  interfaces  run

What's the contents of /etc/config/wireless of AP?

*Below is the attach file for the content of /etc/config/wireless/*


*I am connecting STA to the wireless AP **FSL_AP1gn shown in attached file
and it is connected to the network in which dhcp-server is present.*

*And Both the laptops are in same lan and I am using Compact wireless 3.6
version.*

Thanks for your help but I am still struggling for the same.
But I think its due to 4 address compatibity mode .

What's the contents of /etc/config/network and /etc/config/wireless of both AP and STA?

Since this is a Layer 2 connection both the laptops should be in the same network, e.g. 192.168.1.1/24  for laptop1 and 192.168.1.2/24 for laptop2.

Hi All,

I am facing issue regarding 4 address mode in Board acting as Station using
ath9k, Below is setup details:


Laptop1 -------(AP)      -------     (STA)-------Laptop2
                 atheros              ath9k

I have added wireless interface of STA into Bridge, to do so i have enabled
4 address mode on Wlan interface. AP is using atheros drivers and added
WLAN interface into bridge.

Able to connect ath9k Station to AP but not able to get IP on
Laptop2/bridge of STA, this is surely related to compatibility of 4 address
mode with atheros.
I tried enabling WDS mode on AP side but it is also not working.

Please let me know how to solve this issue, i think this is very common
setup and by doing some configuration it should work.

Thanks in Advance.

[Kamran Nishat]

hello can we force ath9k to send every packet as an AMPDU. Currently if
there is only one packet in the queue then ath9k tell the hardware to just
send it as MPDU.
Is there a way to ask driver to wait for more packets and send them as
AMPDU? Simple wait is not working in ath_tx_start(),  ath_tx_send_ampdu()
or ath_tx_form_aggr().

Any help will be highly appreciated.

[Yashashree Jadhav]

Hello ,

Can any tell ...How to fix transmission rate in ath9k driver

During experiment when I put one node on monitoring node....on wireshark....
I found MPDU's within 1 A-MPDU shows different transmission rate.As per my
understanding
in 802.11n all MPDU withing A-MPDU should transmit with the same
transmission rate .
Also in case of failure if transmission rate change then there should be
block ack received intermediately after that failure...but
I found group of MPDU transmit with various transmission rate...and then
one block ack is received....I couldn't identify how exactly aggregation
work
in ath9k driver.

Also if I fixed transmission rate  echo 15 > fixed_rate_idx ....as
aggregation turn of ....and agg. default set to 1....performance degrade
badly...

So , I want some proper way to fix transmission rate...like in madwifi
driver  with command line it is possible to set TX rate.

Regards,
Yashashree

Hello oiioeu,

I just saw your question.Same performance I also experience during my

But, as per active research group of ATH9K ,many researcher says  "A-MSDU
aggregation yet not supported by ath9k".
But , I am also interested ,if some one give there opinion abt it.

STA says Max AMSDU length is 3839 bytes, what was interesting: if I remove the
MAX-AMSDU-7935 option from the wireless configuration file of the AP, the STA
will show:
Max AMSDU length: 7935 bytes

then how to obtain the real 7935 bytes of the AMSDU length? Thank you !

For my own part, my MB is an old MSI MS-6390. I notice that booting with 
acpi=off seems to alleviate the problem to *some* extent, but it still 
happens. Going without wmm and 11n also helps a bit, but not fully...

Please post the output of 'lspci' on your system,
and if you can reproduce the problem, the output of 'dmesg'
with the error visible.

Motherboard, OS, and any other info should be helpful as well.

My hope is that if we can get enough detailed reports we
might can see a pattern.

Thanks,
Ben

I was getting the same error message, when using my card (TP-LINK-WN851ND) with hosted (in master mode) as an access point. After few minutes of steady transfer at about 7-8 Mbytes network was going down with repeating "Failed to stop TX DMA" messages..  

tried out compat-wireless 3.0, 3.1, and 3.2_rc

We do it in our propiertary driver, obviously not in FreeBSD or Linux. Longest link we

Just as a side-point; hasn't someone come up with a way of just doing

The chainmasks are limit set of antennas used for RX and TX, both settings can be
changed in debugfs 'ieee80211/phyX/ath9k'. The distance limit is all Aheros cards
property due to maximum setting for the ACK timeout. It can be set with
'iw phy <phyname> distance <distance>' command. Of course, you need a high gain antenna
to achieve long range communication.

I think no any modifcations of the driver code are required. If your card has MIMO
capability (based on AR9160, AR9220, AR9280, AR9380 or AR9390 chips) you need to set
RX/TX chain masks to 1 and connect your antenna to the fisrst chain connector. For the
long links you need to adjust coverage class value. Maximum distance limited by hardware
is about 50km for 20MHz and 25km for 40MHz bandwidth.

The driver doesn't care much about the antenna. You just need to
connect your directional antenna to the u.FL connector on the wifi
card, inside your laptop. There's not likely any external antenna
connector, so you'll probably have to modify the laptop case to make
dealing with the external antenna convenient.

[subham das]

I would like to connect a Directional Antenna to my laptop Atheros wireless
card by some way/means and still use the ath9k driver to transmit/carry the
network connection to a far of (long) distance as much as possible on the
Line Of Sight. My basic idea is transmitting/carrying ( not routing) the
network connection to a long distance, wirelessly because doing the same
using wired would be expensive compared to the former. So my question is, if
this is feasible and if yes then which Atheros wireless card would be best
in this case and if necessary which files/codes to be changed so that
efficiency would increase interms of range/distance in carrying the internet
connection in a direction ( not routing in omni-direction).

Thanking you in advance

I too have been seeing the problem where beacons stop with ath9k on an
ar71xx-based router.

I've been running with this patch for about 48 hours, and the beacons
are still going. Previously, they would stop after 6-12 hours. Looks
good!

Hello,

I have a TrendNet 652-BRP running OpenWRT + ath9k very well.  The only 
problem is that the beacon gets stuck maybe once a day.  After 
Vasanthakumar Thiagarajan's "ath9k: cleanup beacon parameters 
configuration" patch, ath9k would nearly re-configure the beacons after it 
detected the stuck beacon, and did a reset.  But it would fail the 
SC_OP_TSF_RESET check in ath_beacon_config_ap.  This patch gets the beacon 
fully reconfigured after the reset.

I tried Intrepid but for some reason the wireless was too slow... just logging to yahoo mail took like a minute or so... I don't know i am using the same .config file from my 2.6.25 kernel when i compile 2.6.27-rcx kernels (from kernel.com) and enable the (new) ath9k driver before compiling. 

Last night i was amazed by the speed when i used the non-kernel driver. I mean i actually went to hulu.com and watch a high-res vid with tcpdump -v running in the background. 

Maybe the debian kernel is patched with something i dont know about than the kernel from kernel.com

Something about tcpdump was it kept saying "unknown 802.11 header (3)" something like that at times.

We now have ath9k in compat-wireless-old (for kernels <= 2.6.26).
But please note more effort is being put into updating ath9k
upstream. compat-wireless-old essentially is a fork of mac80211
and its drivers for support on older kernels. Developers wishing
to contribute to it can further bring patches from wireless-testing
to it (please send patches to compat-masters list).

There have been some new patches which fix some drop connection issues
(group key patch) which has been pushed out to 2.6.27 and on
wireless-testing.

I'd recommend to try 2.6.27-rc7 with the group key patch and MIB
interrupt disable patch. I guess we should put these pending patches
somewhere, then we just have to apply them to compat-wireless-old too.

Help with this is greatly welcomed as compat-wireless-old is lead
by the help of the community.

The wireless works fine, just at times drops connections the things that fixes it is removing the module and loading it again:
rmmod ath9k
modprobe ath9k
iwconfig wlan0 essid ...
dhclient wlan0

don't know if this helps the dev's to debug (regarding the dropped connection issues) or someone trying to get AR9281 wireless cards to work on any debian flavor. Any feed back would be appreciated.

Thanks,
Vib

"iwlist wlan0 scan" does show my router. 
I have another box with broadcom wireless card and it works fine running gentoo linux.

I recently installed Elive (debian flavor) of linux and compiled kernel 2.6.27-rc6 inorder to get ath9k. My card is a atheros AR9281. I use 802.11g at home. ? What i can't seem to understand is that i can't get a dhcp offer. I am sitting right next to my router and get no ip on: dhclient wlan0. ? i have checked everything here is the command i use to set my wireless when i have a my key enabled: iwconfig wlan0 essid "rcvc" key s:xxxx open channel 8 mode Managed ? Any thing i missed? Thanks for the help. 
does "iwlist wlan0 scanning" show your AP ?

can you use an other box or wifi card supporting monitor mode at the same time to try to see if something happend (go out of your card) ?
