我正在尝试通过控制台连接到已知的网络（稍后将其放入脚本中）。迄今为止最有前途的命令似乎是这个：
nmcli con up "Weelaan" ifname wlp4s0
这至少将我的 WLAN 托盘图标变成加载动画，并且看起来它正在尝试连接到正确的网络，但过了一会儿我收到错误通知和以下输出：
Error: Connection activation failed: The Wi-Fi network could not be found
Hint: use 'journalctl -xe NM_CONNECTION=eef66f76-9566-4e3c-889c-9634960dd1b7 + NM_DEVICE=wlp4s0' to get more details.
运行该提示命令会在相应时间给出以下输出：

只需单击网络托盘图标，然后单击网络上的“连接”按钮即可，但我不想接管该脚本中的鼠标。这也将使其依赖于屏幕分辨率，并会产生许多其他不良副作用。那么nmcli问题是什么？我该如何解决这个问题？它与 KDE 的网络菜单有什么不同？
答案1
显然，您需要nmcli device wifi rescan先执行，即使该网络已知并且已经出现在可见网络列表中。
