Of course, if the development board is connected to an Ethernet or HDMI display, you can also use the commands demonstrated in this section to connect to the WIFInetwork.''' 网络使用会有问题。

'''1、服务器版镜像通过命令连接WIFI'''{| class="wikitable" style="width:800px;background-color:#ffffdc;"|-|当开发板没有连接以太网，没有连接 '''HDMI''' 显示器，只连接了串口时，推荐使用此小节演示的命令来连接 '''WIFI''' 网络。因为 '''nmtui''' 在某些串口软件（如 '''minicom'''） 中只能显示字符，无法正常显示图形界面。当然，如果开发板连接了以太网或者'''HDMI''' 显示屏，也可以使用此小节演示的命令来连接 '''WIFI''' 网络的。|}1) 先登录 First log in to the linux 系统，有下面三种方式system, there are the following three ways<br>a. 如果开发板连接了网线，可以通过 If the development board is connected with a network cable, you can remotely log in to the Linux system through ssh 远程登录 linux 系统<br>b. 如果开发板连接好了调试串口，可以使用串口终端登录 linux 系统If the development board is connected to the debugging serial port, you can use the serial port terminal to log in to the Linux system<br>c. 如果连接了开发板到HDMI 显示器，可以通过HDMI 显示的终端登录到linux 系统If the development board is connected to the HDMI display, you can log in to the linux system through the terminal displayed on the HDMI<br><br>2) 首先使用 First use the '''nmcli dev wifi''' 命令扫描周围的 command to scan the surrounding WIFI 热点hotspots<br>

3) 然后使用 '''Then use the nmcli''' 命令连接扫描到的 command to connect to the scanned WIFI 热点，其中：hotspot, where：<br>a. '''wifi_name''' 需要换成想连接的 needs to be replaced with the name of the WIFI 热点的名字hotspot you want to connect to<br>b. '''wifi_passwd''' 需要换成想连接的 needs to be replaced with the password of the WIFI 热点的密码hotspot you want to connect to<br>

3) 输入 Enter the nmtui 命令打开的界面如下所示command to open the interface as shown below<br><br>

4) 选择 Select '''Activate a connect''' 后回车and press Enter<br><br>

5) 然后就能看到所有搜索到的 Then you can see all the searched WIFI 热点hotspots<br><br>

6) 选择想要连接的 Select the WIFI 热点后再使用 hotspot you want to connect to, then use the Tab 键将光标定位到 key to position the cursor on '''Activate''' 后回车and press Enter<br><br>

7) 然后会弹出输入密码的对话框，在 Then a dialog box for entering a password will pop up, enter the corresponding password in '''PsswordPassword''' 内输入对应的密码然后回车就会开始连接 and press Enter to start connecting to WIFI<br><br>

8) After the WIFI 连接成功后会在已连接的 connection is successful, a "*" will be displayed in front of the connected WIFI 名称前显示一个“*”name<br><br>

9) 通过 You can view the IP address of wifi through the '''ip addr show wlan0''' 命令可以查看 wifi 的 IP 地址command<br>
