/lib/firmware/iwlwifi-4965-2.ucode  /lib/firmware/iwlwifi-7265-9.ucode
/lib/firmware/iwlwifi-5000-5.ucode

• 重启后，再检查驱动是否生效：

dmesg | grep iwlwifi

• 效果：

• 如果顺利，将有新网络设备：

$ nmcli dev                                                                                                      
DEVICE     TYPE              STATE        
eth0       802-3-ethernet    connected  
wlan0      802-11-wireless   disconnected   

• 扫描wifi网络1：

sudo iw dev wlan0 scan | less

• 效果：

    HT capabilities:

• 扫描wifi网络2：

iwlist wlan0 scan

• 手动连接：

nmcli dev wifi connect <YOUR_SSID_HERE> password <YOUR_KEY_HERE>

• <YOUR_SSID_HERE>为wifi名称，<YOUR_KEY_HERE> 为wifi密码

• 如果连接成功，wlan0显示为connected

• 查看详细的连接信息：

$ iwconfig wlan0

• 效果：

wlan0     IEEE 802.11abgn  ESSID:"Euclid"

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

• 查看WIFI信号强弱：

$ iwconfig wlan0 | grep -i --color quality   //查询网络连接质量着红色
          Link Quality=47/70  Signal level=-63 dBm 

$ iwconfig wlan0 | grep -i --color signal    //查询信号强度着红色
         Link Quality=44/70  Signal level=-66 dBm 

异常问题：

• 问题：提示缺少iwlwifi-7260-7.ucode
• 修复：

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7260-ucode-22.1.7.0.tgz
sudo cp iwlwifi-7260-ucode-22.1.7.0/iwlwifi-7260-7.ucode /lib/firmware/
