This tutorial is a rewritten of the previous ‘Fix \u2018No WiFi Adapter Found\u2019 for HP Laptops with Ubuntu 18.04<\/a>‘, since wireless will stop working after installed or upgraded to a new Linux Kernel.<\/p>\n

Following steps will install the newest Realtek rtlwifi codes including rtl8192ce<\/b>, rtl8192cu<\/b>, rtl8192se<\/b>, rtl8192de<\/b>, rtl8188ee<\/b>, rtl8192ee<\/b>, rtl8723ae<\/b>, rtl8723be<\/b>, rtl8821ae<\/b>, rtl8822be<\/b> and rtl8723de<\/b> in Ubuntu with DKMS<\/b> (Dynamic Kernel Module Support) support. So it will work in each kernel on your system.<\/p>\n

UPDATE: Ubuntu now supports RTL8723DE out-of-the-box! For other RealTek wifi drivers, try this tutorial<\/a> instead.<\/b><\/p>\n

1.<\/b> Connect your laptop to a wired network, and then open terminal from application menu.<\/p>\n

\"\"<\/p>\n

2.<\/b> Run command to install some required tools:<\/p>\n

sudo apt install git build-essential dkms<\/pre>\n
Type user password (no asterisk feedback due to security reason) when it prompts and hit Enter.<\/i><\/p>\n
\"\"<\/p>\n
3.<\/b> Now grab the rtlwifi_new codes via command:<\/p>\n
git clone -b extended https:\/\/github.com\/lwfinger\/rtlwifi_new.git<\/pre>\n
\"\"<\/p>\n
4.<\/b> Add the source to the tree for builds with DKMS support.<\/p>\n
sudo dkms add .\/rtlwifi_new<\/pre>\n
\"\"<\/p>\n
5.<\/b> Finally install the drivers via command:<\/p>\n
sudo dkms install rtlwifi-new\/0.6<\/pre>\n
\"\"<\/p>\n
6.<\/b> If everything works OK, Wifi should work immediately (it works in my case in Ubuntu 19.04).<\/p>\n
If not, try commands to load the new installed module (rtl8723de in the case):<\/p>\n
sudo modprobe -r rtl8723de && sudo modprobe rtl8723de<\/pre>\n
7.<\/b> And Wifi works after reboot without doing any configuration, at least in my case in Ubuntu 19.04.<\/p>\n
If not, try command to write it into configuration file (replace 3<\/b> to 1<\/b>, 2<\/b> or 4<\/b> if signal is weak).<\/p>\n
echo \"options rtl8723de ant_sel=3<\/b>\" | sudo tee \/etc\/modprobe.d\/rtl8723de.conf<\/pre>\n
In addition<\/b>, if you happened to update your system with newest Kernel packages without reboot. You need to reinstall the kernel packages to get the module work after reboot.<\/p>","protected":false},"excerpt":{"rendered":"
