Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01) 确实给我带来了麻烦。
我在使用新的 HP ENVY 15t 时遇到了很多麻烦。我安装了 ubuntu 14.04，可以看到 wifi 网络，但无法连接。我尝试按照 ubuntu 的在线说明安装 broadcom 驱动程序，但没有任何成功。

我很乐意发布您可能需要的任何信息来帮助我解决这个问题。我试过运行
sudo apt-get --reinstall install bcmwl-kernel-source
因为我知道这是一张 Broadcom 无线网卡。我尝试查看 rfkill 列表，但一切都畅通无阻。请帮帮我，我变得非常沮丧
