![如何在 Ubuntu 20.10 中使用 WPA3 和受保护的管理框架?](https://linux22.com/image/1022138/%E5%A6%82%E4%BD%95%E5%9C%A8%20Ubuntu%2020.10%20%E4%B8%AD%E4%BD%BF%E7%94%A8%20WPA3%20%E5%92%8C%E5%8F%97%E4%BF%9D%E6%8A%A4%E7%9A%84%E7%AE%A1%E7%90%86%E6%A1%86%E6%9E%B6%EF%BC%9F.png)
我在运行 Ubuntu 20.10 的 Dell Latitude-7480 笔记本中安装了 Intel AX-210。我想使用 Wi-Fi 6E、WPA3 和受保护的管理框架(6 GHz 下都需要)进行连接。
驱动程序是 iwlfifi /lib/firmware/iwlwifi-ty-a0-gf-a0-59.ucode
Ubuntu 看到了 SSID,但无法连接。它多次显示“激活网络连接失败”的弹出消息。
我正在看关于20.04 版的 WPA3。
接受的答案提供了以下步骤:
nmcli conn show
NAME UUID TYPE DEVICE
mywifi xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxxx wifi wlp1s0
...other connections here...
然后,我们使用 nmcli 交互式编辑器修复正在使用的 key-mgmt,如下所示:
nmcli conn edit mywifi
我的系统显示如下:
$ nmcli conn show
NAME UUID TYPE DEVICE
WiFi-6E-Test 2 b84117dd-fa12-4dba-b273-61f5fe3c9af1 wifi wlp2s0
Wired connection 1 0f8fd576-7856-3fc4-b8fe-7e524e3fe47d ethernet enp0s31f6
WiFi-6E-Test 4019de60-86ee-48e1-bb3c-43dfef87f79e wifi --
WiFi-6E-Test 1 bd490295-3372-4c4b-b906-7aa9c14e2490 wifi --
系统尝试连接时,第一行“WiFi-6E-Test 2”为红色。有线连接为绿色,其他 Wi-Fi 连接为白色。实际 SSID 为 Wi-Fi-6E-Test。我不确定为什么要添加 1 和 2,但可能是尝试过不同的安全类型(无、OWE 和 WPA3)。
我尝试了这个过程,但似乎密钥管理已经是 sae 了:
$ nmcli conn edit "WiFi-6E-Test 2"
===| nmcli interactive connection editor |===
Editing existing '802-11-wireless' connection: 'WiFi-6E-Test 2'
Type 'help' or '?' for available commands.
Type 'print' to show all the connection properties.
Type 'describe [<setting>.<prop>]' for detailed property description.
You may edit the following settings: connection, 802-11-wireless (wifi), 802-11-wireless-security (wifi-sec), 802-1x, ethtool, match, ipv4, ipv6, tc, proxy
nmcli> print wifi-sec.key-mgmt
802-11-wireless-security.key-mgmt: sae
nmcli> describe wifi-sec.key-mgmt
=== [key-mgmt] ===
[NM property description]
Key management used for the connection. One of "none" (WEP), "ieee8021x" (Dynamic WEP), "wpa-psk" (infrastructure WPA-PSK), "sae" (SAE), "owe" (Opportunistic Wireless Encryption) or "wpa-eap" (WPA-Enterprise). This property must be set for any Wi-Fi connection that uses security.
nmcli> set wifi-sec.key-mgmt sae
nmcli> verify
Verify connection: OK
nmcli> save persistent
Connection 'WiFi-6E-Test 2' (b84117dd-fa12-4dba-b273-61f5fe3c9af1) successfully updated.
nmcli>
到目前为止,这还没有奏效。是否需要其他设置来启用对受保护管理框架的支持?
我还尝试将 AP 更改为机会无线加密而不是 WPA3。我重复了 nmcli 步骤,但使用了 owe 而不是 sae。这也不起作用。使用 OWE 不会出现重复的消息“激活网络连接失败”。它只是默默地失败了。
在这两种情况下,SSID 在“选择网络”对话框中可见,但它永远不会关联。
以下是使用 WPA3 连接 AP 失败时执行 sudo tail -f /var/log/syslog 的结果:
