[ath9k-devel] Ath9k: changing regulatory domain
Hello all, I am quite new to the ath9k driver and I am currently trying to use this driver for an access point on the 5GHz band. The problem is that my card has a regulation domain set to WORA_WORLD 0x6A which prevents the card to do active probing on any 5GHz channel. I tried setting different country codes but this does not improve the situation, so I suspect that the limitation comes from the regulatory domain. So I am now looking to a way to adapt the reg_domain on the EEPROM of the Wifi card. On some posts, I found references to the ath_info tool to modify the reg_domain on the EEPROM but I did not even manage to install this tool yet. So, would someone know any other method to adapt the reg_domain? Thanks in advance for any answers or advices. Best regards ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel

That's exactly what I did, also, I had to add the vendor ID in the hw_init
function for the driver to fully load. I got it to work after making these
changes in the ath9k driver.
yes i missed it, you could got in debug messages.
Now I have a different problem. In AP mode using hostapd, the driver doesn't
transmit at a higher rate than 54Mbit. The iw tool reports only non-HT data
rates. Does the vendor id need to be added somewhere else as well for the
rate control algorithm to load 802.11n HT rates? Using iperf I can only
get a transmit rate up to 29Mbps. However, when I transmit from an 802.11n
station, it works like you would expect, a throughput of 70-80 Mbps.
you need enable in .config
IEEE 802.11n (High Throughput) support
CONFIG_IEEE80211N=y
and also in hostapd.conf
Note: You will also need to enable WMM for full HT functionality.

Re: [ath9k-devel] Sparklan WPEA-121N AR9382 168c:abcd
Which .config? Are you speaking of buildin hostapd with 802.11n support?
I do have ieee80211n set to 1 in hostapd.conf. I have used the same
hostapd.conf with other 802.11n cards and it worked just fine, I will attach it
nonetheless.

Re: [ath9k-devel] Sparklan WPEA-121N AR9382 168c:abcd
Do I absolutely need Kernel 2.6.36 for AR9382? I am running 2.6.35 at the
moment.
One of the AR9382 based radio's vendors got back to me and mentioned that I
need that for the driver work right.
I did compile
http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2011-03-31.tar.bz2
on Ubuntu Natty 2.6.38 and it had the same issue.

Do I absolutely need Kernel 2.6.36 for AR9382? I am running 2.6.35 at the
moment.
you need =2.6.36 as mentioned in
http://linuxwireless.org/en/users/Drivers/ath9k
One of the AR9382 based radio's vendors got back to me and mentioned that I
need that for the driver work right.
he should have meant that =2.6.36
I did compile
http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2011-03-31.tar.bz2
on Ubuntu Natty 2.6.38 and it had the same issue.
but i have 2.6.32-25-generic ubuntu and used the same compat-wireless.
so for compat wireless, 2.6.36 is not a constraint.

That's exactly what I did, also, I had to add the vendor ID in the
hw_init function for the driver to fully load. I got it to work after
making these changes in the ath9k driver.
yes i missed it, you could got in debug messages.
Now I have a different problem. In AP mode using hostapd, the driver
doesn't transmit at a higher rate than 54Mbit. The iw tool reports
only non-HT data rates. Does the vendor id need to be added somewhere
else as well for the rate control algorithm to load 802.11n HT rates?
Using iperf I can only get a transmit rate up to 29Mbps. However, when
I transmit from an 802.11n station, it works like you would expect, a
throughput of 70-80 Mbps.
you need enable in .config
IEEE 802.11n (High Throughput) support
CONFIG_IEEE80211N=y
and also in hostapd.conf
Note: You will also need to enable WMM for full HT functionality.
#ieee80211n=1
Thank you!

Hello All,
I recently purchased a Sparklan WPEA-121N, it uses the AR9382

when I load that ath9k modules nothing comes up.
Does ath9k support this chipset? I compiled compat-wirless on Ubuntu
10.10 on an x86 Core2Duo machine.
lspci -vvvnn returns the following:
02:00.0 Ethernet controller [0200]: Atheros Communications Inc.

Yes AR9382 is supported in ath9k, your device id 'abcd' ?
Did you check with the latest compat wireless?

Cool. Serene, see if you can find the code that handles CSA. This is where the AP makes the decision to change channel and informs all associated stations about the new details. The stations then try re-associating to the new channel. That may do exactly what you're after!
