I have checked in my windows boot if the wifi is working there and it works fine but when checking in my ubuntu there is no wifi I can only connect using ethernet cable or hotspot.

I tried sudo apt update then sudo apt upgrade but no changes occurred.

I even tried updating the software in the ubuntu system but still no changes occured.

And when I type lshw -C network in terminal it shows the below text

When I type in lsmod | grep iwl it shows the below text

Try lspci. That should return the wireless chipset.

Also, check out this article: https://itsfoss.com/install-additional-drivers-ubuntu/

@frankbell when I try lspci I get the following but no wireless chipset

And when I click on Additional Drivers I can only see NVIDIA Corporation drivers nothing else in terms of wireless wise.

That's odd. I don't see any reference to a wireless adapter, unless I'm missing something (which is quite possible).

Have you tried checking out the link to the article. It tells how to use Ubuntu's "Additional Drivers" function, which has worked quite nicely for me in the past.

As an aside, when you post terminal output, please surround it by "code" tags, which become available when you click the "Go Advanced" button beneath the compose/edit post window. It makes terminal output easier to read.

I just tried lsusb and I got the following

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 06cb:00f9 Synaptics, Inc.

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I believe the wireless adapter is the Intel 2725 which is the ax210. The kernel version that supports the adapter is 5.10+ which is Ubuntu version 21.

Yes thats true I thought so too but the kernel version is correct too set to 5.11 when I checked using sudo dpkg --list | grep linux-image I got the following:

ii linux-image-5.11.0-27-generic 5.11.0-27.29~20.04.1 amd64 Signed kernel image generic
ii linux-image-5.11.0-41-generic 5.11.0-41.45~20.04.1 amd64 Signed kernel image generic
ii linux-image-generic-hwe-20.04 5.11.0.41.45~20.04.19 amd64 Generic Linux kernel image

So not sure why the wifi is not working though?

Assuming michaelk is right, you have two easy ways to get your kernel to new enough version.

Hardware Enablement (HWE) Currently at 5.11 or 5.13...
-OR-

OEM currently at 5.14
Then reboot.

edit:didnt see the message that you're already at 5.11 before posting this, so maybe not solution, but still wouldn't hurt to try, intel drivers are almost always included in kernel in my experience...

Maybe you need to install the firmware
https://www.intel.com/content/www/us.../wireless.html

Hi @enigma9o7 when I tried the one for hardware enablement (HWE) I got this

linux-generic-hwe-20.04 is already the newest version (5.11.0.41.45~20.04.19).

Check this thread

https://askubuntu.com/questions/1326...e-ax210-160mhz

Anytime I try to do git clone so that I can install from the available installers in github its not working either.

Most likely since you're running a 5.11+ kernel, your issue is firmware. Can you post the output of a

In https://www.intel.com/content/www/us.../wireless.html

When I downloaded the kernel I needed and extract the files I cant copy them to the firmware either
