No Wifi Adapter Found: Dell Precision 5690: Ubuntu 20, 22, 24

[shaikhsaad]

I know this is a common problem for Dell and there are many related discussions. However, those seem not to work for me.

Issue: I recently bought Dell precision 5690. It came with Ubuntu 24.04 and the wifi was working. But for a specific package, I needed to install Ubuntu 20.04. Once I setup 20.04, wifi is no longer working. It says "No Wi-Fi Adapter Found". Afterwards, I tried with Ubuntu 22.04, 24.04, all have the same issue.

Typing "lspci" provides: "Network Controller: Intel Corporation Device 272b (rev 1a)" and "Subsystem: Intel Corporation Device 40f0". But no exact device name is printed.

From BIOS setup, I tried disabling WLAN and then restarting and Enabling again, and so on. It does not work.

Important: Dell precision 5690 does not have port through which Ethernet cable can be connected. Moreover, Bluetooth device is also not working. 

Question: How can I resolve this without using Ethernet (and wifi not working).

Hello shaikhsaad,

Thank you for posting in the community!

I understand that your system is unable to detect your wireless card. To assist you better, I have a few questions regarding this issue:

1. Could you please share the reason for installing Ubuntu 20.04? According to the DELL Precision 5690 manual, this operating system is not officially supported (page 17).
2. What is the model of the wireless card currently installed in your system?
3. Have you reached out to DELL for assistance with this matter?

I look forward to your response so that we can further investigate this issue.
