WIFI 6E 带 6GHz - Ubuntu 22.04 无法连接

我在连接专用 6 GHz 网络时遇到问题。过去，我升级到最新的 Ubuntu 22.04 LTS 内核版本以获取有效的固件。之后，我现在可以看到所有需要的通道，包括 2,4/5/6 GHz，就像它应该的那样：

乍一看配置似乎没问题。我在内核上运行6.2.0-36-通用#37~22.04.1-Ubuntu和核心72。如果我尝试连接到 2.4/5 GHz，一切都会按预期进行：

root@cloud:/etc# wpa_supplicant -c /etc/wpa_supplicant.conf -i wlp2s0

但如果我尝试连接到我的专用 6 GHz 网络，连接就会卡住：

Successfully initialized wpa_supplicant
wlp2s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=WORLD
wlp2s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=COUNTRY alpha2=DE
...

wlp2s0: CTRL-EVENT-DSCP-POLICY clear_all

wlp2s0: CTRL-EVENT-TERMINATING

所以需要你的帮助来弄清楚，这种“不连接”的根本原因是什么。

与此同时，我和另一位专家一起找到了解决方案。似乎“wpa_supplicant”不会自动在 6 GHz 网络上使用 WPA3，并尝试使用在该信道上不起作用的 WPA/WPA2。

因此我将配置更改为所需的最少部分：

root@cloud:/# cat /etc/wpa_supplicant/wpa_supplicant.conf
network={
        ssid="<my network>"
        key_mgmt=SAE
        sae_password="<my password>"
        ieee80211w=2
}
