我正在使用 ubuntu-server 20.04 映像作为桌面（通过 taskel 安装的 UI）。
我已经一个多星期没法建立 wifi 连接了，所以我们来这里吧。
使用 Network-Manager 时，我可以从 UI 和iwlist wlp3s7 scan|grep ESSIDnmtui 查看我的网络 SSID。但每当我尝试连接时（通过 UI 和 nmtui），系统都不会提示我输入密码。
networkd 是默认配置的（由 subiquity 提供）。networkd 和 Network-Manager 都与以太网无缝连接。
我已经完成并撤消/etc/netplan/00-installer-config.yaml了/etc/wpa_suplicant.conf。当触发后者时，sudo wpa_supplicant -c /etc/wpa_supplicant.conf -i wlp3s7我收到该错误消息wlp3s7: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="Wine Hat" auth_failures=1 duration=10 reason=CONN_FAILED
顺便说一下，这些文件包含我的密码（或它的哈希值），但我将它们全部恢复，但仍然没有从 UI 或 nmtui 收到提示。
我试过“编辑连接界面”，但大多数时候所有字段都呈灰色。但有时我设法输入密码，但仍然没有效果。我还想说，我很熟悉这个密码，而且我考虑到自己容易出错，所以我复制/粘贴/重读了密码。我没有拼错。

当我在 /etc/ 上搜索我的密码时，我得到了这些文件。这些.backup是我试图保留我的更改但被禁用的。wpasupplicant 提供了密码的哈希值。networkmanager 肯定是导致没有密码提示的原因。但我的连接仍然在建立之前超时

其他“单元”也检测到了，但我想连接到“Wine Hat”，我认为我没有访问限制，因为最近我已将一部新手机连接到该网关，而没有更改配置。我一直在研究网关的接口（http://192.168.1.1/），这是我连接失败时的日志行：
Oct 20 00:22:56 daemon.err odhcp6c[5883] Failed to send DHCPV6 message to ff02::1:2 (Permission denied)
diag@diag-srv:~$ ping6 localhost
ping6: connect: Cannot assign requested address
我仍然可以在我的路由器上看到 IPv6 错误消息（它们似乎出现了 2 个或 3 个），最上面的一个是最新的：
Oct 20 22:08:27 daemon.err odhcp6c[31292] Failed to send DHCPV6 message to ff02::1:2 (Permission denied)
Oct 20 22:07:42 daemon.notice odhcpd[2900] Got DHCPv6 request
Oct 20 22:06:42 daemon.info odhcpd[2900] Using a RA lifetime of 0 seconds on br-lan
这是新扫描返回的结果。我没有删除前一个，因为 Wine Hat 使用的频道不再相同（即使我重新启用 IPv6）。因为下面的代码片段已经非常长了，所以我包含了有关无线板功能和配置的更多信息。

鉴于我的无线网卡显示的比特率和频率，并根据那篇文章，前者似乎在 802.11g 协议下运行。我实际上很困惑，因为 lspci 显示的是较早的 802.11n，这可能是由过时的 WEXT API 引起的，因为同一篇文章这么说？同时我的路由器配置为 802.11b/g/n，所以两者都应该很好。
至此，我已经没有主意了 :/ 感谢阅读 :)
特别感谢 Heynnema 的调查。
