sudo apt-get install git
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install

这里会提示很多依赖找不到文件，重启一般就可以看到wifi了，如果还看不到，继续

Reboot and if the wireless doesn't work, in terminal

dmesg | grep iwl | nc termbin.com 9999
cd backport-iwlwifi
make clean
make defconfig-iwlwifi-public
make -j4
sudo make install
