Question

Problem-＆GT;我想知道如何为GB以外的国家/地区的模式a / b / g / n测试通道（WIFI）。

H / W - ＆gt; WIFI sparklan WPEA110N
芯片组：Atheros AR9280
接口：Mini PCI Express

软件 - ＆gt;
Linux fedora 11
无线接入点实用程序 - ＆gt; hostapd

到目前为止我做了什么 - ＆gt;
1）我更改了hostapd_minimal.conf的配置文件，并将国家代码从GB更改为CN（CHINA）或US（USA）等任何其他国家/地区。
2）我也试图改变CRDA EX-＆GT; iw reg set CN

这些更改的结果 - ＆gt;
我注意到它成功阻止了GB以外国家/地区不允许的频道，例如在中国，模式频道 36 是不允许的，因此hostapd的结果变为false但它甚至不允许在中国合法允许的渠道。

摘要 - ＆gt; 简而言之，如果我将国家/地区从GB更改为任何其他国家/地区，则hostapd实用程序仅允许使用公共渠道。例如1）如果我将国家改为美国它将允许36,38,40等用于模式a ，因为这些是两个国家的合法渠道，但不允许通道149 -165

有人可以点亮它。

谢谢和问候，
萨姆

 Well  after couple of days of struggle . I have found  the solution.  Well  Remember this  is only for testing wireless inside  my house. Using of channels which are not authorised in a particular country  are illegal and can be prosecuted.

 To summarize what I did..( may be it wil be helpful for someone)
 Its 2 MAIN stEP PROCEDURE . 
     - First to MAKE CHANGES IN wireless-regdb and
     - Second with crda

 1)WIRELESS-REGDB

   1.a)Download wireless-regdb-2008.11.17.tar.bz2 package
   1.b) Untar it
   1.c) cd wireless-regdb-2008.11.17
   1.d) vi db.text and made changes what you have mentioned
   1.e) make
   This will create a public and priv key in my case its something like key.priv.pem

   1.f) copy the regulatory.bin to /usr/lib/crda/
        (create crda if does not exist)

   if you guys want to make changes in regulatory.bin after the make then
   i) edit db.txt and make reguire changes
   ii) compile it . ex ./db2bin.py regulatory.bin db.txt key.priv.pem
   iii) copy into /usr/lib/crda

          ****************** Now download and commpile crda*******

  2.a) Download Crda . I n my case its crda-1.1.2.tar.bz2
  2 .b) un tar it and cd into directory
  2.c) copy the public key from wireless-regdb into pubkeys directory
  example — cp bla bla/wireless_regdb-2008.11.17 blabla/crda-1.1.2/pubkeys

 2.d)make the file .. type “make”
 note — in my case I got hell lot of errors and dependency problem but google has                      helped me to solve it
 2.e make install
 2.f reboot the system.

 Important — modify frequency in db.txt of the country which your driver is requesting    from EEPROM of H/w.
 for example -> if your driver get counrty code as GB and you made changes for US , it   will not work.

 Best bet is to check what your country code is by typing “iw reg get ” command
