No WiFi adapter found in Ubuntu 18.04, HP Laptop 15q-bu0xx

[zueore]

I've installed my Ubuntu 18.04 with minimal installation mode with keeping the option to install WiFi drivers along. But still I couldn't use the WiFi, since the setting is showing that there is no WiFi devices found.

Attaching pastebin link from terminal outputs. Tried most of the solutions mentioned in forum like , sudo apt-get install --reinstall bcmwl-kernel-source

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

Reboot
If you notice 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

Wow! That was a huge help. Thanks.

thank you jeremy 31, Now wifi adapter is on.

Is there any way to do run this modrobe command automatically while booting up? It's becoming irritating to run this everytime inorder to connect to WiFi!

[jeremy31]

Yes

echo "options rtl8723de ant_sel=X" | sudo tee /etc/modprobe.d/rtl8723de.conf

Replace X with whatever setting worked best
