[SOLVED] Wifi not working Realtek RTL8723DE

Post by Credulous_Skeptic » Fri Nov 30, 2018 5:52 am

Hi,
I am new to linux and just installed linux mint 19 in dual boot with windows 10 pro. My wifi is not working in mint. I did the installation with a wired connection. In windows 10 device manager the wifi adapter is shown as Realtek RTL8723DE 802.11b/g/n PCIe Adapter. Somebody please help.
My laptop is HP 15-da0077tx.

Do

Code: Select all

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
Check mokutil --sb-state and if it says Secure Boot is enabled, you will need to disable in BIOS/UEFI when you reboot

Code: Select all

cd rtlwifi_new
make
sudo make install
make clean
Reboot
If you don't want to have to run those commands after every kernel update figure out how to add Secure Boot keys as they don't need to be deleted
