我最近在一台 2007 年的旧 MacBook 上安装了 Lubuntu。通过专有驱动程序，我设法激活了 WiFi 模块。
我可以在笔记本电脑上看到 AP，并尝试连接它们，但过了一会儿就超时了。我找到了一种或多或少可靠的解决方法。通过使用 创建新连接nmcli device wifi connect ssid password pass，我有时可以连接到网络。
问题是它会创建一个新的连接，必须清理这个连接，这样我的学生才能可靠地使用笔记本电脑，而无需知道 WiFi 密码。

我想知道这是否有帮助？我注意到您的芯片组（BCM4321）未列出。并且您的连接使用了不同芯片 ID 的驱动程序。«wlan0：Broadcom BCM4328»
