Hello,

i want more 11a channels. so i tried to modify the countrycode to germany.

# ifconfig ath0 list freq
Channel   1 : 2412* Mhz 11g          Channel  10 : 2457* Mhz 11g
Channel   2 : 2417* Mhz 11g          Channel  11 : 2462* Mhz 11g
Channel   3 : 2422* Mhz 11g          Channel  12 : 2467* Mhz 11g
Channel   4 : 2427* Mhz 11g          Channel  13 : 2472* Mhz 11g
Channel   5 : 2432* Mhz 11g          Channel  14 : 2484* Mhz 11b
Channel   6 : 2437* Mhz 11g          Channel  34 : 5170* Mhz 11a
Channel   7 : 2442* Mhz 11g          Channel  38 : 5190* Mhz 11a
Channel   8 : 2447* Mhz 11g          Channel  42 : 5210* Mhz 11a
Channel   9 : 2452* Mhz 11g          Channel  46 : 5230* Mhz 11a


# sysctl -a dev.ath.0
dev.ath.0.%desc: Atheros 5212
dev.ath.0.countrycode: 392
dev.ath.0.regdomain: 64



# cat /boot/loader.conf
...
dev.ath.0.countrycode=276
hw.ath.countrycode=276


i tried to set the countrycode to germany in the loader.conf.
as you can see the sysctl still displays dev.ath.0.countrycode as japan.
anyone an idea how to set the countrycode or what mistake i do?
has anyone more information about regdomain?

thx.

Hello,

after playing around with a software named "Channel set utility" i get for my wlan card the following error message during boot (dmesg)

ath1: unable to collect channel list from hal; regdomain likely 96 country code 276
device_attach: ath1 attach returned 22


so switching to other channels will be disabled from the HAL driver. is there anyone outside who can give me more backround information or an hint where to continue my investigation?

For all others who buy an atheros card: take care which country code this card has. if you get one with japan country code in europe that the card can not be adjuted to all 11a channels.

Hi everybody again,

so i solved the problem. here my short summary. please write an PN if you have further questions.

if you buy an atheros miniPCI wlan card, run it with pfsense and get only 4 11a channels then have a look at "sysctl -a dev.ath.0.countrycode" in an terminal window. if its something like 392 then you get an japan restricted version (with oly 4 11a channel in 5GHz band).
my solution for this: if you have an miniPCI to PCI adapter download the "Channel set utility", put the card into an windows xp pc and unlock all channels.
after this you but your card back into your pfsense system (in my case an WRAP board). don't put any countrycode etc in loader.conf. then you get such a nice channel list

Nice but where are the turbo channels or is that card not turbo capable?

[MdeWendt]

Hi hoba,

you are right. i have an atheros AR5004X (http://www.atheros.com/pt/AR5004XBulletin.htm) which normaly supports this 108Mbps turbo mode. i have never seen this mode in my list. i think there is an eeprom where countrycode etc is stored and all futures are enabled.
has anyone a datasheet about the AR5213 Multiprotocol MAC/baseband processor and can figure out that? or send it to me i will have a look at it.

This is what my card shows withou patching anything, however I'm missing turbo g channels:

$ ifconfig ath0 list channel

Hello hoba,

it seems to be a problem of this hal driver:

Hello hoba,

it seems to be a problem of this hal driver:

That's so strange because the linux and BSD drivers use the same HAL,when I list the channels in linux there's a couple 11g turbo channels.
So what's up with the BSD drivers?

[lsf]

AFAIK, the linux driver has the same HAL if it's the normal madwifi driver. The madwifi-ng driver is different iirc.
