You unscrew the small screw that keeps the mPCIe wifi card in place lift it out and throw it in the fish tank where it becomes part of the amusing detritus of social commentary and landscape art you've been contributing to.

Now pop in the $18 Intel card you ordered last night and landed a hour ago.

Your done !

Oh wait ! NOOB, you forgot to replace the screw !

And then you throw the entire laptop after the card, because your new Intel WiFi card isn't on the whitelist.

Most cards have m2 interface nowadays; so you'd like to have an adapter too. Also mPCIe cards tend to use two screws, not one.
