我无法连接到无线网络

我试图用 lubuntu 连接到 wifi，但是无法连接，我不知道具体是什么问题，我使用了 nm-applet，结果如下：

    nm-applet

** (nm-applet:13926): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

(nm-applet:13926): nm-applet-WARNING **: Failed to register as an agent: (32) An agent with this ID is already registered for this user.
nm-applet-Message: using fallback from indicator to GtkStatusIcon

更新：

于是我重新安装并再次尝试，结果如下：

family@family-HP-Compaq-6735s:~$ lspci -knn | grep Net -A2

答案1

如果你可以通过有线连接到互联网，那么只需在终端中运行

sudo apt-get install bcmwl-kernel-source
sudo modprobe -r b43 bcma

如果你无法通过其他方式连接，请使用这种方法

答案2

对我来说，安装“at-spi2-core”允许我成功运行 nm-applet，并连接到 wifi 网络。

sudo apt install at-spi2-core
