Wi fi not working

I have just installed Ubuntu Mate on a Dell Computer which was running Windows XP. My WI FI does not work. I can't find the wireless adaptor. The Wi-Fi was working when running Windows XP.

Welcome
I connect to Internet with WiFi hotspot so I may be totally wrong in the following image. If so no problem. In image after 6 a new screen will pop up where you can enter it.

Hi jsknight100,
As I understand, you don't know the name of your wireless adapter.
For the beginning, read and try this , step by step.

I have done that but nothing happens!

inxi -N should list the network drivers.

lsusb is another way.

Thanks for your comment. I run lsusb & no network drivers were shown!

I assume that Dell laptop has internal wireless card.
In this case, lsusb is wrong command. It is correct for usb adapters.
For the internal card, correct command:
lspci

There are two Ethernet controllers & a Communication Controller Data/Fax modem

John ...
post the output of inxi -N or the output of inxi -F (use </> to format it)
What's the DELL laptop model ?

When I typed inxi -N I received command inxi not found but can be installed with : sudo apt install inxi
then received message password for john

Is it possible to copy text from the terminal?

I managed to copy & paste.

[email protected]:~$ inxi -n

Command 'inxi' not found, but can be installed with:

sudo apt install inxi

[email protected]:~$ sudo apt install inxi
[sudo] password for john:
Sorry, try again.
[sudo] password for john:
Sorry, try again.
[sudo] password for john:

sudo: 3 incorrect password attempts

Hi is it possible on your initial input of inxi -N you left out the space between the i and the -?

According to my notes UM 22.04 has inxi installed by default. So which UM did you install?

also I keep asking about the laptop model.

My computer is a desktop Dimension 5150
I installed Mate 1.24.0

No I just checked too make sure!

This was the result of running lsusb Thanks for your help.

As @mendy wrote, try lspci | grep Wireless and paste output.

Wasn't me. :grinning:

This was the result of lspci

Nothing seemed to happen!
lspci | grep Wireless
This is what I typed.
