2) 然后使用 '''lsusb''' 命令就可以看到 rtl8821cu usb wifi 模块的设备信息，请确保 USB模块没有处于 Driver CDROM Mode<br>

orangepi@orangepi:~$ '''lsusb | grep "Realtek"'''<br>
Bus 002 Device 003: ID 0bda:c820 Realtek Semiconductor Corp. 802.11ac NIC

orangepi@orangepi:~$ '''lsusb | grep "Realtek"'''<br>
Bus 002 Device 002: ID 0bda:1a2b Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter '''<span style="color:#0066CC;">(Driver CDROM Mode)</span>'''<br><br>
'''如果 lsusb 命令看到的 USB WIFI 模块处于 Driver CDROM Mode，请重新拔插下 USB WIFI 模块。如果还不行，请手动执行下面的命令切换下模式：'''<br><br>
orangepi@orangepi:~$ '''sudo usb_modeswitch -KW -v 0bda -p 1a2b'''

3) linux 系统会自动加载 rtl8821cu 蓝牙和 wifi 相关的内核模块，通过 lsmod 命令可以看到下面内核模块已自动加载<br>

|orangepi@orangepi:~$ '''lsmod'''
{| class="wikitable" style="width:800px;"

| 8821cu || 1839104 || 0
|-
| rtk_btusb || 61440 || 0
|}
|}
4) 通过 dmesg 命令可以看到 rtl8821cu 模块的加载信息<br>

5) 然后通过 '''sudo ifconfig''' 命令可以看到 rtl8821cu wifi 的设备节点，wifi 的连接和测试方法请参看 <span style="color:#0066CC;">[[Orange Pi 5 detail#WIFI 连接测试 | WIFI 连接测试]]</span>一节，这里不再赘述<br>
