UBUNTU - No WiFi Adapter Found - hp pavilion rtl8723de

HP Recommended
pavilion rtl8723de
Linux

Hi everyone!

 

I got "No WiFi Adapter Found" on my dual booted hp pavilion rtl8723de. The othe OS is windows 10, and there the wifi works properly.

I found this answer:

https://h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/Realtek-8723DE-wifi-module-amp-Blueto...

but the problem stays....

Is any other option for me to be done? Will downgrade be useful?

 

Thank you so much,

Erez

Hi

This may be covering ground you have already trod, if so Sorry.

 

Courtesy of Bapoumba, Ubuntu Forums
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.

 

This I guess you have tried already....

Thanks

I'll try with wired Internet today.

 

EDITED:

IT WORKED!

I've done the first 'box' of instructions, only the updates lines.

Then the instruction box from github.

Attention!
