ubuntu 16.04 裝機無wifi (手動匯入wifi驅動)

電腦新裝的ubuntu16.04 開機沒有wifi顯示,設定中的網路裡也看不到wifi選項,可能是驅動沒有

1.通過設定-軟體和更新-附加驅動 檢視不到可更新的wifi驅動。

2.手動安裝無線網絡卡驅動

現在檢視網絡卡名稱:

~$ lspci -knn | grep Net -A2
3d:00.0 Network controller [0280]: Intel Corporation Device [8086:2526] (rev 29)
Subsystem: Bigfoot Networks, Inc. Device [1a56:1550]
3e:00.0 Non-Volatile memory controller [0108]:

ubuntu下檢視到裝置名。

如果是雙系統的話,在Windows下控制面板-裝置管理器中可以查到無線網絡卡具體型號,我的電腦無線網絡卡型號是 :

Killer(R) Wireless-AC 1550 Wireless Network Adapter (9260NGW)

如果此時網絡卡型號不同,可以搜尋型號+ubuntu,下載deb檔案手動安裝,重啟即可。詳情參考:

手動安裝 

此時不要去搜索Killer(R) Wireless-AC 1550 Wireless Network Adapter (9260NGW)該驅動,因為現在能下載到的都是windows10版本驅動。ubuntu下安裝該驅動如下操作:

Intel recently added the VID and PID to their backports, to install

~$ 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

這裡會提示很多依賴找不到檔案,重啟一般就可以看到wifi了,如果還看不到,繼續

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

dmesg | grep iwl | nc termbin.com 9999

and post the URL from terminal in a comment as we made need to get firmware from upstream

After a kernel update you will need to

cd backport-iwlwifi
make clean
make defconfig-iwlwifi-public
make -j4
sudo make install
