Issue with WIFI Driver

[adapco]

My issue is whenever i am trying to install Wifi Driver it doesnt install hence doesn't work although my LAN is woring fine.

I am facing the issue since 2016 when i first formatted my system.

Earlier with Windows 8 Wifi was working perfectly fine but when i installed Windows 7 this issue started. I tried installing all the drivers including wireless driver given on HP website for my model but it didn't work . After multiple format and driver installation the issue didn't resolve.

Recently when i tried again then i saw a message that "This driver is not supported on the machine or OS (Doesn't rememeber exactly)" as a result now i tried installing Ubuntu v.18.04 with kernel 4.15.0-43-generic

But again the same issue on Ubuntu too LAN is working and WIFI isn't.

After too many hours waisting on multiple answers from the community i came across this thread (https://h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/Realtek-8723DE-wifi-module-amp-Blueto...) . I tried all the steps but one thing which i noticed is that there is no Wireless Driver present on my system and i am still searching for answer.

Extremely disappointed using HP Laptop.
FYI this is the snapshots of my wifi adapter not found.

When troubleshooting wireless, it's important that your system is fully updated by opening a terminal, CTRL+ALT+T. Using a wired internet connection, please run:
Code:

sudo apt update
sudo apt dist-upgrade

and reboot if necessary.

If the issues persist, it is recommended that you install pastebinit, by running:
Code:

sudo apt install pastebinit

This will enable the wireless script to, upon your approval, upload the obtained data to pastebin, creating at the same time a link to it in your terminal, permitting you to paste it to a forum thread.

Once that's done, download and run the wireless info script, which will gather information to help diagnose your system. You can run it using this command:
Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

It will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz". If you prefer, you can post the file directly to pastebin yourself. Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.

If you aren't able to connect to the internet with the affected system, including via a wired connection, just navigate to this link and follow the instructions there on how to the run wireless script without an internet connection.
