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

772

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

所以最近我购买了带有 CD 上驱动程序的双频 USB 适配器，以安装在 Windows、Mac 和 Linux 上。

我正在使用Ubuntu 18.04.4 LTS - 64 位

1. 将适配器连接到USB端口后，我检查了输入终端的端口lsusb，我得到以下信息：

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

2. sudo dkms status然后我什么也没得到。

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

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

您的无线现在应该可以工作了。
