#bcm4313

Who would have known that all I had to do was open Terminal and type something. But before this, I did this: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#STA_-_Internet_access

Then I went into Terminal and typed something I thought I already did before but apparently didn't..

sudo modprobe acer_wmi sudo modprobe -r acer_wmi

I'm not sure if the second part will work without doing the instructions in the link. But after I typed that stuff in the Terminal, my wifi was enabled right away on Ubuntu and Linux Mint, when before, I couldn't even enable the damn thing. It just never let me click "ON".
