BCM43142 网卡驱动

1. 安裝閉源驅動 bcmwl-kernel-source

1-1. https://help.ubuntu.com/community/WifiD ... er/bcm43xx
Broadcom STA Wireless driver (Proprietary)
For Chip ID BCM 4311, 4312, 4313, 4321, 4322, 4331, 4352, 4360, 43142, 43224, 43225, 43227, 43228, and others as suggested by Broadcom.
The propietary Broadcom STA Wireless driver is maintained upstream by Broadcom. As this driver is closed source, fixes in the driver itself may only be provided by Broadcom. As a convenience, Ubuntu offers two versions of this driver:
The bcmwl-kernel-source package aims to offer a later version for a given release. Instructions for installation may be found later in this article.

没有有线的情况下

2. 可以從 同一版本 Ubuntu Live USB/DVD 安裝 bcmwl-kernel-source
2-1. 把 Ubuntu Live USB/DVD 加入 /etc/apt/sources.list
https://help.ubuntu.com/community/Repos ... -ROM.2FDVD
CD-ROM/DVD
2-2. https://help.ubuntu.com/community/WifiD ... net_access
STA - No Internet access
If you do not have any other means of Internet access on your computer, you can install the bcmwl-kernel-source package from the restricted folder under ../pool/restricted/b/bcmwl on the Ubuntu install media.
sudo dpkg -i bcmwl-kernel-source*

从 http://packages.ubuntu.com/ 下载包手动安装。
安装 bcmwl-kernel-source 前，先手动解决一部分依赖，如直接列在 http://packages.ubuntu.com/xenial/bcmwl-kernel-source 中的软件包：
linux-headers-`uname -r`
dkms
libc6-dev
linux-libc-dev
然后可以尝试安装 bcmwl-kernel-source，过程中提示缺啥就去 http://packages.ubuntu.com/ 'Search package directories' 搜索下载。注意 'Distribution' 要选 'xenial'(16.04)

在附加驱动里找找

可以从网上买个无线网卡呀，插到usb接口就能连上wifi，反正以后万一重装系统什么的肯定会用得着的。
