:::How to Install RTL8723DE Wifi Driver in Ubuntu 19.04 Hello lutz, i am using 18.04 and hp 15 pavilion cw0096nb, this wifi adapter rtl8821ce was also not working !, intill i went to the updatemanager in ubuntu, the A in the black round background app,i have download about 500 mb, it went to a higher kernel and other updates ,REBOOT your computer, then i have used all the commands in a terminal as here discribed above. You need to reinstall the kernel packages to get the module work after reboot. In addition, if you happened to update your system with newest Kernel packages without reboot. echo 'options rtl8723de ant_sel= 3' | sudo tee /etc/modprobe.d/nf If not, try command to write it into configuration file (replace 3 to 1, 2 or 4 if signal is weak). And Wifi works after reboot without doing any configuration, at least in my case in Ubuntu 19.04. If not, try commands to load the new installed module (rtl8723de in the case): sudo modprobe -r rtl8723de & sudo modprobe rtl8723deħ. If everything works OK, Wifi should work immediately (it works in my case in Ubuntu 19.04). Finally install the drivers via command: sudo dkms install rtlwifi-new/0.6Ħ. Add the source to the tree for builds with DKMS support. Now grab the rtlwifi_new codes via command: git clone -b extended Ĥ. Type user password (no asterisk feedback due to security reason) when it prompts and hit Enter.ģ. Run command to install some required tools: sudo apt install git build-essential dkms Connect your laptop to a wired network, and then open terminal from application menu.Ģ. The post is out-dated! You can now install one of these RealTek Wifi drivers via an Ubuntu PPA.ġ.
