Recently I installed Ubuntu next to Windows 10 and when I try to connect it to wifi it says "wifi adapter not found".
For every solution I've seen it says I need ethernet (I'm using USB ethernet through my phone, I don't know if that is a problem).
I have secure boot disabled and when I go to Additional Drivers it says that there are no additional drivers found.
If I enter the command
lspci -knn | grep Net -A3; rfkill list I get
