Ubuntu wifi rtl8723de 升级到 18.04LTS 后无法工作 
nishanthr@vision:~$ lspci -v | grep -i network  
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device d723

为 Realtek Semiconductor RTL8723DE 设备安装 Wi-Fi 驱动程序 [10ec:d723] 我在 16.04LTS 时已经尝试过这个，现在我再次尝试时它说

nishanthr@vision:~$ git clone -b extended --single-branch
https://github.com/lwfinger/rtlwifi_new.git fatal: destination path
 'rtlwifi_new' already exists and is not an empty directory.

然后我做了这个

cd rtlwifi_new/ && git checkout origin/extended -b extended   
sudo make install
sudo modprobe -r rtl8723de  
sudo modprobe rtl8723de

也尝试过

sudo apt purge bcmwl-kernel-source  
sudo sed -i '/blacklist bcma/ d' /etc/modprobe.d/blacklist.conf   
sudo sed -i '/blacklist brcmsmac/ d'/etc/modprobe.d/blacklist.conf

并尝试更换天线

sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=X (X=1,2)

并重新启动了几次但仍然不起作用。
