我已经运行了以下脚本但都徒劳无功......
sudo apt install git dkms
git clone -b extended --single-branch https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add rtlwifi_new
sudo dkms install rtlwifi-new/0.6
sudo apt update
sudo apt install build-essential dkms git
git clone https://github.com/jeremyb31/rtl8723de.git
sudo dkms add ./rtl8723de
sudo dkms build rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
如果出现错误，则：
sudo apt-get install dkms git build-essential
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
sudo cp -r rtlwifi_new/firmware/rtlwifi/ /lib/firmware/rtlwifi/
echo "options rtl8723de ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723de.conf
echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be.conf
重启

按照 chili555 建议的步骤操作后，WiFi 工作正常。问题现已解决。
答案1
您的无线设备是 Intel 设备。您安装的 Realtek 驱动程序和参数对 Intel 设备无效。虽然您安装的驱动程序没有好处，但也没有坏处。您可以放心地保留 Realtek 驱动程序和参数。
但是，如果您像我一样相信良好的管理，请删除 Realtek 驱动程序：
sudo dkms remove rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414 --all
并删除无效的参数：
sudo rm /etc/modprobe.d/rtl8723be.conf
现在，让我们让英特尔工作起来。根据此错误报告引用您的确切 8086:02f0 设备，固件文件 iwlwifi-QuZ-a0-jf-b0-*.ucode 也是必需的。https://bugs.launchpad.net/hwe-next/+bug/1833065
它不存在于您的 1.173.12 版本的 linux-firmware 中。
通过以太网、网络共享或任何可能的方式建立有效的互联网连接，打开终端并执行以下操作：
sudo apt-get update
sudo apt-get install linux-oem-osp1
wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb
sudo dpkg -i linux-firmware*.deb
重新启动并显示：
