BCM4311-没有启用Wi-Fi的选项

我有 Ubuntu 16.04。我看不到任何启用 wifi 的选项。我在软件和更新中选择了 Broadcom 驱动程序，并且 BIOS 中启用了 Wi-Fi 开关。

我浏览了帮助页面并运行了以下命令：

$ sudo lshw -C network
  *-network               
       description: Network controller
       product: BCM4311 802.11b/g WLAN

我应该怎么办？

$ lspci -knn | grep Net -A3; rfkill list

    Kernel driver in use: b43-pci-bridge
    Kernel modules: ssb, wl

通过有线方式连接到互联网并运行

sudo apt purge bcmwl-kernel-source
sudo apt install firmware-b43-installer

然后重新启动。
