在 Ubuntu 18.04.4 上安装双频 USB 适配器 2.4/5GHz Wi-Fi 时出现问题

Question

\n
• \n

\n

双频 USB 适配器 2.4/5GHz 1200(866+300)Mbps 无线速度，支持 802.11ac

\n

所以最近我购买了双频 USB 适配器，并附有 CD 上的驱动程序，以便在 Windows、Mac 和 Linux 上安装。

\n

我正在使用Ubuntu 18.04.4 LTS - 64 位

\n

1. \n将适配器连接到 USB 端口后，我检查了在终端中输入的端口lsusb，得到以下信息：

\n

Bus 001 Device 007: ID 0bda:b812 Realtek Semiconductor Corp.\n

\n

2. \nsudo dkms status然后我什么也没得到。

\n

3. \n然后我在 CD 中名为 ( RTL81888192EUS_linux_v4.3.0.4_11485.20140519 )的文件夹中安装 Wi-Fi 2.4GHz ，在终端中输入chmod +x install.sh，然后sudo ./install.sh得到以下结果：

看来该文件夹中不存在文件rtw_cmd.o，因此失败。

该文件夹中似乎也不存在文件rtw_cmd.o，因此它也失败了。

\n

- \n那么有人可以修复Wi-Fi 2.4GHz 和 5GHz 两个文件夹中的文件rtw_cmd.o吗？

\n

这些文件夹位于以下链接中：适用于 Linux 的双频 USB 适配器 Wifi

Answer 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

您的无线网络现在应该可以工作了。
