Answer 1

以太网

编辑你的/etc/network/interfaces如下：

# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
    
auto lo
iface lo inet loopback
 
auto eth0
iface eth0 inet dhcp

要通过以下方式使互联网正常工作eth0：

ifdown eth0
ifup eth0

无线上网

更新

smlinux存储库上提供了可用的驱动程序（请参阅评论）

要安装rtl8723de驱动程序，您的内核版本应该 >=4.11。

最简单的方法是安装 Debian Stretch，然后从向后移植升级您的内核版本（内核 4.13可用）

要在 Debian Jessie 上安装，rtl8723de您应该编译内核 >4.11

安装过程：

驱动程序可以按如下方式安装：

git clone https://github.com/smlinux/rtl8723de.git
cd rtl8723de
make
make install 

适用于 Linux 内核版本 5 的 Realtek RTL8723DE 模块：

git clone https://github.com/smlinux/rtl8723de.git -b current
dkms add ./rtl8723de
dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
depmod -a
reboot

更新Debian 10

该驱动程序可在lwfinger/rtw88上使用：

注意：1）只要发行版未修改任何内核 API，此代码将构建在任何内核 4.19 及更高版本上。

2. 该存储库包含以下卡的驱动程序：

RTL8822BE、RTL8822CE、RTL8821CE 和 RTL8723DE

sudo apt-get update
sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git

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

sudo modprobe -rv rtw_8723de 
sudo modprobe -v rtw_8723de
