双频 USB 适配器 2.4/5GHz 1200(866+300)Mbps 无线速度，支持 802.11ac
所以最近我购买了双频 USB 适配器，其驱动程序位于 CD 上，可安装在 Windows、Mac 和 Linux 上。
我在用着Ubuntu 18.04.4 LTS64位
1.
将适配器连接到 USB 端口后，我在终端中检查了端口输入lsusb，得到了以下信息：
Bus 001 Device 007: ID 0bda:b812 Realtek Semiconductor Corp.
2.
sudo dkms status从此以后我就什么也没有了。
3.
然后我去安装 Wi-Fi 2.4GHz，位于名为 (RTL81888192EUS_linux_v4.3.0.4_11485.20140519) 在 CD 中，在终端中输入chmod +x install.sh，然后sudo ./install.sh我得到了以下结果：

- 那么有人可以修复文件吗rtw_cmd.o可以在 Wi-Fi 2.4GHz 和 5GHz 两个文件夹中吗？
文件夹位于以下链接中：适用于 Linux 的双频 USB 适配器 Wifi
答案1
首先，确保安装了必要的先决条件：
sudo apt update
sudo apt install --reinstall build-essential dkms git
git clone https://github.com/cilynx/rtl88x2bu.git
cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu
你的无线网络现在应该可以正常工作了。
