16.04无线驱动问题

[husy]

我按网上在系统设置的附加驱动安装了网卡的专有驱动重启后没有任何变化，依旧是没有wifi的选项，只能有线连接。
但是网上也找不到支持我现在网卡的驱动了，如何能支持wifi呢？
这是我的一些信息：

16.04无线驱动问题

sudo lshw -C net

configuration: driver=bcma-pci-bridge latency=0

1. 無線網卡 BCM43142
已載入驅動 bcma-pci-bridge
但缺少
logical name:
serial:
等項
表示 沒有成功驅動

2. 建議
測試 無線網卡時
把有線網卡 從 Bios 關閉
以免打擾
然後重新開機 看看 有沒有改變
2-1. 等測試 無線網卡 成功
再視需要 從 Bios 打開有線網卡

3. 參考這個方法 重新安裝 BCM43142 驅動
http://askubuntu.com/a/52181
然後重新開機看看 有沒有改變
3-1. BCM43142 在 wl 支援名單內
3-1-1. https://help.ubuntu.com/community/WifiD ... rietary.29
Broadcom STA Wireless driver (Proprietary)
較新的無線網卡 BCM43142 需要安裝 bcmwl-kernel-source 套件 提供 wl 驅動模組
3-1-2. https://wiki.debian.org/wl
wl

但是网上也找不到支持我现在网卡的驱动了

BCM43142 是惟一一款 LCN40 PHY 无线网卡，开源驱动 b43/brcm80211 不支持，仅有私有驱动 wl 可供使用

附加驱动安装了网卡的专有驱动重启后没有任何变化

可能原因 wl 构建失败，但由于是的在“附加驱动”中安装的，导致用户无法看到或容易忽略错误信息
尝试：

代码： 全选

1. apt purge bcmwl-kernel-source broadcom-sta-dkms
2. 重新启动计算机
3. apt install linux-headers-`uname -r` build-essential dkms
4. apt install bcmwl-kernel-source

注意观察 4. 输出的信息。可将 4. 输出的信息完全复制贴上来

这里执行到第二步的时候，

代码： 全选

root@husy-X202E:/home/husy# apt install linux-headers-'uname -r' build-essential dkms
正在读取软件包列表... 完成
正在分析软件包的依赖关系树       
正在读取状态信息... 完成       
E: 无法定位软件包 linux-headers-uname -r

我刚开始学习，对这些指令都不太理解，但是执行起来得到上面的结果，这是为什么呢？

[vickycq]

root@husy-X202E:/home/husy# apt install linux-headers-'uname -r' build-essential dkms
E: 无法定位软件包 linux-headers-uname -r

不是 linux-headers-'uname -r' 而是 linux-headers-`uname -r`
不是单引号，而是反引号(ESC下方，TAB上方)
反引号的作用 参考
https://www.gnu.org/software/bash/manua ... ution.html
http://unix.stackexchange.com/questions ... g-backtick
http://unix.stackexchange.com/questions ... n-commands

即 若执行 uname -r 输出 4.5.0-2-amd64
则 linux-headers-`uname -r` 等同于 linux-headers-4.5.0-2-amd64
