我有一台 Ubuntu 20.10 系统，它支持 airmon-ng 在 6 GHz 频段使用 Wireshark 进行数据包捕获：
++ sudo airmon-ng start wlp2s0 6335
PHY Interface Driver Chipset
phy0 wlp2s0 iwlwifi Intel Corporation Device 2725 (rev 1a)
(mac80211 monitor mode vif enabled for [phy0]wlp2s0 on [phy0]wlp2s0mon)
(mac80211 station mode vif disabled for [phy0]wlp2s0)
++ iwconfig
wlp2s0mon IEEE 802.11 Mode:Monitor Frequency:6.335 GHz Tx-Power=-2147483648 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:on
我有一台相同的笔记本电脑，版本号为 21.04，它将作为客户端连接，并通过从终端运行 wpa_supplicant 在 6 GHz 信道上运行。
sudo wpa_supplicant -i wlp2s0 -c /home/me/wpa_sae_config.conf -ddsBtK -g /tmp/wpa_global -G me
但是它不会加载 airmon-ng：
$ sudo airmon-ng start wlp2s0 6335
phy0 wlp2s0 iwlwifi Intel Corporation Device 2725 (rev 1a)
Error setting channel: kernel reports: Channel is disabled
command failed: Invalid argument (-22)
Unable to set channel/frequency 6335, most likely it is outside of regulatory domain
两个系统文件都有我将 21.04 系统更改为的/etc/default/crda行，但这对 airmon-ng 使用 6 GHz 的能力没有影响。 两个系统都具有 Intel AX-210 并且具有相同的驱动程序，如报告所述：REGDOMAIN=REGDOMAIN=USsudo lshw -C network
configuration: broadcast=yes driver=iwlwifi driverversion=5.11.0-051100-generic firmware=59.601f3a66.0 ty-a0-gf-a0-59.uc
监管域是否有并行系统，airmon-ng 使用的系统与 wpa_supplicant 不同吗？报告的底层数据来自哪里iw reg get？
Ubuntu 21.04-airmon-ng 不支持 6 GHz：
