使用以下仓库为驱动GitHub - wandercn/RTL8188GU: Realtek RTL8188GU Driver for TP-link TL-WN725N USB wifiRealtek RTL8188GU Driver for TP-link TL-WN725N USB wifi - GitHub - wandercn/RTL8188GU: Realtek RTL8188GU Driver for TP-link TL-WN725N USB wifihttps://github.com/wandercn/RTL8188GU

推荐使用deb安装方法，避免自己编译，速度快。

• 安装所需的软件包并重新启动

sudo apt install -y dkms raspberrypi-kernel-headers raspberrypi-kernel raspberrypi-bootloader bc build-essential git dh-make

sudo reboot

• dkms deb 安装(提前将该deb下载到树莓派中) 资源在下面https://download.csdn.net/download/goolete/87325565https://download.csdn.net/download/goolete/87325565

dpkg -i 8188gu-dkms_1.0.1_armhf.deb

• 出现以下说明安装完成

DKMS: install completed.
Module build for kernel 5.10.103-v8+ was skipped since the
kernel headers for this kernel does not seem to be installed.

• ​​​​​检查状态

sudo dkms status

8188gu, 1.0.1, 5.10.103+, arm: installed

至此，该驱动成功安装，输入

iwconfig

树莓派板载wifi为wlan0，出现wlan1代表usb无线网卡。

2.如果为 Bus 001 Device 007: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter

树莓派4B直接免驱，插上即可使用。
