Help me to test the power save mode in p2p using wpa_supplicant and ath9k driver

hi,
  I am using ubuntu machines and ath9k driver for testing the of P2P
using wpa_supplicant. I can see all the features in p2p except power
saving technique. please help me to how to  test the power save
technique in p2p using ath9k driver.

Strong signal CCK detect on Hornet / AR9331

hi!

Seems I have a bit of a hairy one.

I've noticed that at least on FreeBSD, Hornet/AR9331 has a problem
receiving strong CCK signals.

note:

19:02:17.492416 202921222us tsft short preamble 6.0 Mb/s -20dB signal
-96dB noise antenna 2 2437 MHz 11g 60us BSSID:40:0e:85:1a:f1:69
DA:60:fe:c5:7d:80:48 SA:40:0e:85:1a:f1:69 Probe Response
(CACHEBOY_PALM) [1.0* 2.0* 5.5* 11.0* 18.0 24.0 36.0 54.0 Mbit] CH: 6,
PRIVACY

.. the BSSID is the (very close, a foot or so) AP transmitting CCK beacons.

Now, I can see RTS/CTS, data frames and probe response frames - all
OFDM and HT frames. However, the CCK beacons aren't being received.

The signal level isn't a mis-parse - the hardware thinks its a very
very strong signal. Scarily strong, in fact.

Has anyone seen this with AR9331?

Difference 40MHz and 20MHz

Hi,
FIRST, Will there be any difference in duration of PHY header for 20MHz and 40Mhz. 
Do u think 40Mhz header will take lesser time?

Second, if my AP is connected to a client on 40MHz (Channel Bonding). During Carrier Sense (CS) it sense ext channel of 20MHz is busy will it automatically switch to 20MHz and start sending on primary channel. If yes will it take some time to shift from 40MHz to 20MHz?

Kamran

why can not i turn off the RTS/CTS on openwrt

Hello,all:

       i use "iw phy0 set rts 2437" or use "iw phy0 set rts off ", or use the ``luci'' web interface, in order to turn off

the RTS/CTS mechanism. Unfortunately, either of the tries do not work. I can see the RTS/CTS packet when

capturing the packet using monitor mode.


       Any advice will hignly be apprecaited!!

Support for Ubnt UniFi Outdoor Plus

Hi List,
I want to use OpenWRT on my Ubnt UniFi Outdoor Plus. So far all works
but the Wifi. The symptoms are poor reception and normal transmission
levels. The problems do not appear using the stock firmware. They only
appear after a power cycle when using OpenWRT. OpenWRT works as expected
if no power cycle was performed after installation. It was suggested
that this is due to the RF filter built into the unit
(https://lists.openwrt.org/pipermail/openwrt-devel/2014-September/028103.html).
Does anyone have some pointers so I can fix this? Perhaps somehow
outputting the content of the registers before doing the power cycle?

Cheers,
Birger

AR9382 spams syslog with loads of "Chip reset failed" messages

Hi!

I bought AR5BHB116 wifi which is half size mini pcie card with 2 antenas for use as an AP with hostapd. Till this moment I can not get that card working as it should work.
I tried multiple machines, kernels and distros and it's all the same, it spams logs with this no matter in what mode - AP or managed:
    [  140.993008] ath: phy0: Chip reset failed
    [  140.993083] ath: phy0: Unable to reset channel, reset status -22
    [  141.427312] ath: phy0: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef DMADBG_7=0xdeadbeef
    [  141.427607] ath: phy0: Could not stop RX, we could be confusing the DMA engine when we start RX up

CPU is busy 100% as it's logging this really fast, although it's just an Atom 330 (dual core + ht).
Even this triggers spamming: ifconfig wlan0 up

What I've tried:
    distros: debian wheezy, archlinux, ubuntu 14.04
    kernels: 3.2, 3.12, 3.13, 3.15, 3.16
    machines: Acer 3610, D2500CCE
    tried nohwcrypt=1, tried power saving off (apparantly it's already off with AP mode)

Guys, what can I do to fix this? Is there anything I can help with debugging?

regards
Eduards

Information Elements

Hello,

I have been working on an iMX6 Sabrelite for some time now, and am using a AR9271 USB dongle to create two virtual interfaces. One as an AP and the other as a station. Everything seems to be working great.

Recently I have been trying to filter out my AP from a list of AP's from the "iw dev wlanX scan", figured out I need to add Vendor Specific information element so that they would be added to the beacon and probe response.

I read that it can be done both from kernel space and user space, added the vendor_elements=dd.. (default something copied from a post) to the hostapd config, and restarted it a few times but it did not have any effect on the scan output.

Any pointers as to where I can add it in Kernel space, or maybe the driver itself? Or any other directions I should look into?

Regards
Rahul Panda

Modifying the data rate of the ath9k driver

Hi,

Forgive me, I am new to driver development. I am working on a project
which requires me to modify the data rate of the ath9k driver. It can be
found at kernel-top-directory/drivers/net/wireless/ath/ath9k. For testing
purposes, it's necessary to set the data rate really low (e.g. 6.5 Mb/s).

I've searched the source code of the driver extensively, but have come up
empty. I know where the RTS/CTS rate is set, but I'm having trouble finding
where the general data rate is set.

Any suggestions as to how and where I might modify the data rate? 

Thanks,

Char

Channel width on packet level

Hi,
Is it possible to change channel width at the packet level in ath9k. For example if AP connected with a client on 40Mhz channel wants to send next packet on 20Mhz primary channel.

ath9K is not recognising AR9220 card (wlm200nx) on 3.15

Hi, I'm struggling to figure out how to debug this, grateful for advice

I have a PCEngines Alix with a wlm200nx wifi card. This should have an 
AR9220 chip in it and be detected by the ath9k driver.  I have built my 
own kernel using linux-3.15.10, however, the ath9k driver isn't 
"recognising" or otherwise appearing to bind to the hardware, even when 
ath9k is modprobe'd

lspci shows:

     00:0c.0 "Class 0280" "168c" "0029" "168c" "2096"

dmesg, shows very little in addition, just a boot time:
     pci 0000:00:0c.0: [168c:0029] type 00 class 0x028000

lsmod
ath9k                  46564  0
mac80211              198136  1 ath9k
ath9k_common            5364  1 ath9k
ath9k_hw              327804  2 ath9k,ath9k_common
ath                    11888  3 ath9k,ath9k_common,ath9k_hw
cfg80211              126984  4 ath9k,mac80211,ath9k_common,ath

Relevant bits of .config are:

CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K_BTCOEX_SUPPORT=y
CONFIG_ATH9K=m
CONFIG_ATH9K_PCI=y
CONFIG_ATH9K_AHB=y
CONFIG_ATH9K_DEBUGFS=y
# CONFIG_ATH9K_STATION_STATISTICS is not set
# CONFIG_ATH9K_WOW is not set
# CONFIG_ATH9K_HTC is not set

I see nothing in syslog when loading the module (well, just one line 
"Calling CRDA to ...").  I have tried adding debug=0xfffffff module 
parameter and that doesn't show anything additional.

I would be extremely grateful for help debugging this further. I'm not 
sure how to debug the module loading to see why it's not recognising the 
hardware.

Note, the same kernel is successfully loading and using a ralink USB 
wifi device, so I don't believe I have completely borked wifi. rfkill is 
disabled (but I don't believe that affects module loading and 
binding?).  Have I missed some firmware?  Do I need some additional 
module included?

Very grateful for any help

Thanks
