I've been wondering around the googles looking for a way to make WiFi work with my new laptop. I haven't ran into Wifi/drivers issues before with Ubuntu but I was never a serious user (I mostly work in OSX/Game in Windows). I'm moving to Linux for work (Don't like apple, Windows is impossible to get anything done with).
I've followed most of the advice I could find, with no real luck. Really could use some hints in how to proceed (currently tethering my phone via usb to keep connected).
I ran the WiFi command recommended when adding the Wifi tag and got this:
