0bda:d 723 Realtek半导体公司802.11n无线局域网适配器不工作于Ubuntu 20.04

Question

我已经在umax笔记本上安装了一个Ubuntu20.04，我找不到任何0bda:d723 Realtek Semiconductor Corp. 802.11n WLAN Adapter的工作驱动程序。

lsusb向我展示了设备，但我找不到wifi网络适配器。

我试过了，但它对我没有用：Ubuntu20.04:我无法编译最新的ndiswrapper

我尝试过其他解决方案(使用类似的wifi卡)：为Realtek半导体723 8723 d设备安装Wi驱动程序[10 Fi:d 723]

在ubuntu 20.04有工作的司机吗？

Answer 1

由于您以前尝试过其他几个驱动程序，因此假设您已经安装了所有的先决条件。

通过以太网、捆绑或任何可能的方式工作的互联网连接，打开一个终端并做：

git clone https://github.com/lwfinger/rtw88.git
cd rtw88
make
sudo make install
sudo modprobe rtw_8723de

你需要禁用安全启动。

每次更新管理器提供更新的内核版本时，都必须重新安装此驱动程序。在请求重新启动后，通过以太网、绑定或任何可能的方式进行临时internet连接，请执行以下操作：

cd rtw88
make clean
git pull
make
sudo make install
sudo modprobe rtw_8723de

你的无线电应该又能用了。请保留rtw88文件和这些说明。
