一、先用lsusb查看usb设备：

#lsusbBus 003 Device 003: ID 0bda:b82c Realtek Semiconductor Corp. 802.11ac NIC

二、根据usb id “0bda:b82c”搜索

https://linux-hardware.org/?id=usb:0bda-b82c

三、搜索Ubuntu(Debian) 8822BU 驱动安装

四、下载驱动源码

sudo apt update && sudo apt upgradesudo apt install -y linux-headers-$(uname -r) build-essential bc dkms git libelf-dev rfkill iwgit clone https://github.com/morrownr/88x2bu-20210702cd 88x2bu-20210702sudo ./install-driver.shSign command: /lib/modules/6.6.38-trim/build/scripts/sign-fileBinary /lib/modules/6.6.38-trim/build/scripts/sign-file not found, modules won't be signedError! Your kernel headers for kernel 6.6.38-trim cannot be found at /lib/modules/6.6.38-trim/build or /lib/modules/6.6.38-trim/source.Please install the linux-headers-6.6.38-trim package or use the --kernelsourcedir option to tell DKMS where it's located.An error occurred. dkms build error:  1Please report this error.Please copy all screen output and paste it into the problem report.Run the following before reattempting installation.$ sudo ./remove-driver.sh

五、解决/lib/modules/6.6.38-trim/build软链接错误

提到重新安装系统可以解决。但重装系统有成本，这里列出另外一种方案。

  • 下载kernel 6.6.38 source

    wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.6.38.tar.xztar -xf linux-6.6.38.tar.xzcd linux-6.6.38

  • 拷贝系统kernel config

cp /boot/config-$(uname -r) .configsudo apt install libncurses-devmake olddefconfig 

  • 编译kernel module

    make modules_preparemake modules -j4 （可能不是必须的，编译所有module,比较耗时，可以跳过，如果后面编译网卡驱动报错再来执行)

  • 建立软连接

    rm /lib/modules/6.6.38-trim/buildsudo ln -s  ~/linux-6.6.38 /lib/modules/6.6.38-trim/build

编译驱动
