我刚刚在我的 Dell Inspiron 1520 上安装了带有 Gnome3 的 archlinux。由于我的 wifi 卡的 pcid 是，所以我使用的是 b43 broadcom 驱动程序14e4:4312。
当我安装 NetworkManager（带有 gnome 密钥环）时，它会看到所有可用的 Wifi 连接，但每当我单击加密连接时，它首先会要求进行管理员身份验证（第一次尝试），然后继续断开连接并自动连接到第一个可用的非加密连接。
是否有某些东西我还没有安装或配置？
以下是日志

答案1
nm-applet 启动时，会将自己注册为 NetworkManager 的“秘密”代理。当 NetworkManager 需要输入密码时，它会要求代理与用户进行交互。
但是，它在我的 Arch 系统上不起作用：
$ pacman -Q network-manager-applet
network-manager-applet 0.9.8.0-1
我从 Git（nma-0-9-8 分支，提交 742e5daf91）编译了 nm-applet，并且成功了。
