最近终于换了垂涎已久的蓝天14寸笔记本新模具，把台式机装有 ubuntu 的硬盘装上笔记本，发现无线网卡不能用, 当然要重新安装驱动, 这个不是问题.

查看网卡信息

$ sudo lspci
[sudo] password for niko:

......
04:00.0 Network controller: Intel Corporation Wireless 3165 (rev 81)

根据网卡信息找驱动

在官网 - Linux* Support for Intel® Wireless Adapters网页上，我们找到了该网卡的驱动信息:

Device	Kernels	Firmware
Intel® Dual Band Wireless-AC 3165 (starting from firmware XX.XX.13.0 and kernel 4.1)	4.2	iwlwifi-7265-ucode-25.30.14.0.tgz

可以看到, 需要是 4.2 的 Linux kernel 版本, 而我的系统通过 uname -r 发现内核版本仍然是 3.13 ，故而不能使用。

升级 kernel

因此我们先升级内核版本来支持该网卡驱动 (参考).

安装完成后, reboot , 查看内核版本:

$ uname -r
4.2.0-040200rc8-generic

更新 grub:

$ sudo update-grub

此时可以发现, 在右上角(gnome)的网络设置中可以选择 wifi 了, 通过 iwconfig 以及 ifconfig 都可以列出 intel 的无线网卡了.
