Pretty common issue, I found many answers and could not figure it out (new linux user here and most things assume some background). Wifi worked while I was installing the OS. I opted for the LTS 20.04.2.0
I have Ethernet cable and connection is established.
I ran 'sudo apt-get install --reinstall bcmwl-kernel-source' and got the following:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Reinstallation of bcmwl-kernel-source is not possible, it cannot be downloaded.

I tried 'sudo apt install dkms' and got this:
Reading package lists... Done

Reading state information... Done
dkms is already the newest version (2.8.1-5ubuntu1).
dkms set to manually installed.

I also checked if the adapter is soft or hard switched off, it wasn't. this must be a driver issue.
I pretty much just want to download the needed package and install it, but I have no clue how to know which one
Final note: I did notice that the .iso file had amd64 at the end and I am using an intel processor. Though I think that this is not the problem since wifi worked perfectly while installing the OS from a USB
