Linux Custom CRDA WiFi regulatory.bin和40MHz BW 5GHz频道
作者：互联网
我正在为Linux上的CRDA创建自己的regulatory.bin.使用我的自定义regulatory.bin,我希望能够为任何5GHz,20MHz或40MHz BW通道创建自己的hostapd热点.
我担心5GHz(不是2.4 GHz),目前所有20MHz BW信道都在工作.现在我想让40 MHz频道工作.
到目前为止,对于40 MHz BW信道,我只能使用信道38和46来创建一个热点.如果我试图高于那个(54,62,102,110,118,126,134,142,151或159),那么hostapd抱怨信道不在受支持的列表基于CRDA允许的渠道.
这是正确的,因为hostapd打印的允许通道不包括这些高40 MHz通道.
但是,我认为它应该可以工作,因为我的自定义CRDA包括我的薄k是正确的频率和BW参数,包括40 MHz频道：
country FK:
(2402 - 2472 @ 40), (30)
(2474 - 2494 @ 20), (20), NO-OFDM
(5170 - 5250 @ 80), (17)
(5170 - 5210 @ 40), (20)
(5210 - 5250 @ 40), (20)
(5250 - 5290 @ 40), (20)
(5290 - 5330 @ 40), (20)
(5250 - 5330 @ 80), (23)
(5250 - 5350 @ 80), (100 mW)
(5470 - 5725 @ 80), (1000 mW)
(5735 - 5835 @ 80), (30)
当我启动hostapd来创建我的WiFi热点时,调试打印根据我的自定义CRDA条目显示以下可选择的通道：

我需要对我的CRDA配置做什么才能使用hostapd获取剩余的40 MHz BW通道？谢谢.
解决方法:
没关系我让这个工作 – 似乎你必须在hostapd配置中指定[HT40-]以及与之相连的上20MHz信道号来创建40 MHz信道.
