networkmanager wifi 未连接，wpa_supplicant 正常

我正在尝试在一台计算机上设置接入点并从另一台计算机进行连接。以下是接入点配置 (/etc/NetworkManager/system-connections/Hotspot.nmconnection)：

[connection]
id=Hotspot
uuid=590dd05e-61eb-41e0-aa4f-b838c5675d77
type=wifi
autoconnect=false
interface-name=wlan0
timestamp=1675612177

[wifi]

channel=149
mode=ap
ssid=MyAccessPoint_5G

[wifi-security]
auth-alg=open

pairwise=ccmp;
proto=rsn;
psk=SuperSecret

[ipv4]
method=shared

[ipv6]
addr-gen-mode=stable-privacy
method=ignore

[proxy]

此配置由

nmcli wifi hotspot ifname wlan0 ssid MyAccessPoint_5G password SuperSecret

在另一台电脑（笔记本）上，我尝试使用 nm-applet 连接此热点。它尝试了几秒钟但失败了，再次要求输入密码。

这是它在 (/etc/NetworkManager/system-connections/MyAccessPoint_5G.nmconnection) 创建的条目

以下是日志：

我使用 wpa_passphrase 创建了一个简单的配置：

network={
    ssid="MyAccessPoint_5G"
    #psk="SuperSecret"
    psk=8c2193dd5c26d1ce18553fdd17e3b1a93af3650f5d1fecaabf7efe2f4c162122
}

当我手动启动 wpa_supplicant 时，它可以毫无问题地连接。

$ sudo wpa_supplicant -cmyap.conf -iwlp5s0

接入点是 Orange Pi Zero 2（Allwinner H616 64 位高性能四核 Cortex-A53 处理器，AW859A 芯片支持 IEEE 802.11 a/b/g/n/ac），运行 Ubuntu 22.04.1 LTS（aarch64）

笔记本是 Thinkpad e480，无线网卡是 Intel Dual Band Wireless-AC 3165，运行 Ubuntu 22.04.1 LTS

答案1

一旦我将 proto 更改为 ，问题就解决了wpa。默认情况下，Hotspot 在创建时将 proto 设置为rsn。

NetworkManager 配置中没有针对 proto 的设置，我从热点日志中找到了答案：

我已经添加了 proto wpa 并且一切正常：

# nmcli connection modify Hotspot 802-11-wireless-security.proto wpa
