Message that states "no wifi adapter found"

[Bob161]

i installed Ubuntu 18.04 on my HP 13-c010nr computer...now I get a "no wifi adapter" message when Ubuntu opens. It worked before Ubuntu was installed. How do I get the computer to switch on the wifi?

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

Hi

Disappointing really, Lubuntu and Linux Mint detect mine automatically.

Thanks for the reply!  However, the HP 13-c010nr laptop computer has only wireless wifi.

1.  Is there another way to get it to work ?

2. Is there a plug-in wireless adapter that will work with this computer and Ubuntu 18.04?
