“iw reg get”与 Wi-Fi 芯片 No-IR 频率之间的差异

我有一个 Intel AX200 Wi-Fi 芯片，想用它在法国托管 5Ghz Wi-Fi AP。

当我跑步时iw reg get，我有这个：

如果我理解正确，我无法使用 更改我的 Wi-Fi 板的国家/地区iw reg set，但是，尽管 DFS 未设置，但国家/地区是正确的，如果我正确理解，则启用 5GHz 频率，而不是“无红外”。

然而，跑步iw phy0 info向我展示了这一点：

                Frequencies:
                        * 5180 MHz [36] (22.0 dBm) (no IR)

                        * 5785 MHz [157] (22.0 dBm)
                        * 5805 MHz [161] (22.0 dBm)

                        * 5905 MHz [181] (disabled)

所有 5GHz 频率要么被禁用，要么无 IR，除了末尾的几个在欧洲不允许的频率。hostapd 拒绝在任何 5GHz 频道（包括 149 至 165）上运行。出了什么问题？

  • 我是否误解了iw reg get输出？
  • 输出有错吗iw reg get？

我可以做点什么吗？

我运行 Ubuntu 20.04、Linux 5.4.0-125-generic 和 crda 3.18。

答案1

我只是觉得PASSIVE-SCAN旗帜暗示了NO-IR。
