Hey,
in addition to the problem I posted some hours ago (see below):
If I configure the regdomain to 0x30 (ETSI) (ath_info -w 0xe0080000
regdomain 0x30) and load ath_pci with
modprobe ath_pci countrycode=276
I am loosing my wifi0 and wifi1 devices. My iwconfig output only shows eth0
and lo.
If I configure the regdomain to 0x00 and load ath_pci with
modprobe ath_pci countrycode=276
iwconfig shows wifi0 and wifi1 like expected but I am (I guess because of
regdomain 0x00) only able to set the txpower to 0dBm (=1mW).
So again my question: How can I configure my modules/driver in a way that
they are configurable for the following frequency ranges:
2402-2482 20dBm
5170-5250 20dBm no-outdoor
5250-5330 20dBm no-outdoor, dfs
5490-5710 27dBm dfs
Most important for me is the frequency band 5490-5710 at a txpower of 27dBm!
Thx a lot.

Hi everyone,
I'm new to this list so hopefully this is the right place for my questions
:)
For my project I have to use 802.11a/h outdoor with high transmission power.
As I am from Europe I am allowed to use the frequency range 5490-5720 with a
maximum EIRP of 27dBm if DFS is supported. I'm developing on an ALIX board
(Voyage OS, kernel 2.6.30) equipped with two Atheros AR5213A based WiFi
modules. The output of lspci -v:
00:0e.0 Ethernet controller: Atheros Communications Inc. AR5212/AR5213
Multiprotocol MAC/baseband processor (rev 01)
Subsystem: Wistron NeWeb Corp. CM9 Wireless a/b/g MiniPCI Adapter
Flags: bus master, medium devsel, latency 96, IRQ 11
Memory at e0080000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [44] Power Management version 2
Kernel driver in use: ath_pci
Kernel modules: ath5k, ath_pci
Initially I started using the ath5k driver. But if I am not wrong it doesn't
support Radar Detection/DFS until now!? As a consequence I switched back to
madwifi.
I checked out the madwifi-dfs branch (r4149, 12.10.2011), compiled and
installed it. With
ath_info -w 0xe0080000 regdomain 0x30
I wrote the ETSI regdomain (0x30) and I set the countrycode to germany (276)
when executing modprobe. You can find the output of ath_info at the end of
this mail.
Nevertheless, if I list the available frequencies with iwlist ath1 freq I
dont get the desired frequency band of 5490-5710:
ath1 35 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Channel 36 : 5.18 GHz
Channel 40 : 5.2 GHz
Channel 44 : 5.22 GHz
Channel 48 : 5.24 GHz
Channel 52 : 5.26 GHz
Channel 56 : 5.28 GHz
Channel 60 : 5.3 GHz
Channel 64 : 5.32 GHz
Current Frequency:5.32 GHz (Channel 64)
I am trying this now for a long time and I really have no idea how to
activate the missing frequencies to be allowed to use up to 27dBm.
