I just recently installed Xubuntu on my laptop alongside Windows 10. I can't find a way to search for Wi-Fi connections as it doesn't give the option. I looked around online, but I didn't find anything that worked.
I had to connect to ethernet to run update and upgrade commands, but it still won't search for Wi-Fi.

SecureBoot enabled
edit:
I turned off secure boot. While the advice here is certainly helping, the issue is not completely resolved. But I'm seeing the wi-fi pop in and out.
After turning off secure boot, I got the Wi-Fi option, but it's popping in and out. It's not staying on. When I do see the available wi-fi option, and I click on it, it starts to load showing a spinning circle, and then goes away and turns back into an up arrow and down arrow ↑↓
