Note: This is not Ubuntu only. I've yet been able to get the wifi working on this machine. I've tried Debian, Arch, Ubuntu, Mint, POP, Arco, among others. WiFi does not work. I keep getting that the wifi adapter cannot be found.

Note: I've found this link stating this laptop is ubuntu certified.

https://ubuntu.com/certified/202103-28860

I'm currently using 23.04 Ubuntu.

==== I installed windows and my wifi does work and drivers / firmware was up to date.

I found this: Dell Latitude 5521 WiFi not working on U20 LTS which the sudo command mentioned there doesn't work i assume because the file is not named that anymore?

This is not a duel boot system.

EDIT 1: What Distro Version:

Ubuntu 23.04 desktop gnome architecture amd64

EDIT 2: I didn't use the ubiquity legacy installer. I used the big bright download button and used what the default iso was.

You mention many OSes without specific details thus the information is of no real use. What likely matters is the kernel stack being used, as that alters the kernel modules (*commonly called 'drivers'*), with Ubuntu LTS releases offering kernel stack choice. You mention OSes, where maybe you should look further than that & contrast what kernel (stacks) work & work from there. Your addition OS detail mentioned none of that. The certified link you gave had it working on an OEM kernel stack, so not GA or HWE defaults of Server & Desktop ISOs (you didn't mention Server/Desktop either)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
