Please help. Wi-Fi adapter not found Ubuntu 18.04 with HP laptop Followed steps mentioned under 1) https://ibcomputing.com/install-rtl8723de-realtek-d723-ubuntu-18-04/#comment-73 2)No wifi option on Ubuntu (18.04 and 16.04)
No Luck !!
lspci -nnk | grep 0280 -A3
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:d723] Subsystem: Hewlett-Packard Company Device [103c:8319] Kernel modules: rtl8723de, wl
Try this: (It worked for me)
sudo apt remove bcmwl-kernel-source && sudo apt install git dkms
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
After running above commands Reboot your system.
If you notice a weak signal try:
sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=1
and see if it is better, if not do
sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=2
And then run following command so that you won't have to run above command everytime you boot your system
echo "options rtl8723de ant_sel=X" | sudo tee /etc/modprobe.d/rtl8723de.conf
Replace X with whatever setting worked best. For me, X was 2.
Note: My laptop model is HP 15-bs145tu
sudo modprobe rtl8723de && dmesg | grep rtl
