WIFI Extender/card for hook up to laptop

I need a heavy duty WIFI extender for my laptop, I need to be able to connect to networks that are 100 kilometres away, does anyone know where I can buy them, any help is appreciated.

Um I'm not even sure this is possible...I would get a hotspot and then connect to a VPN to access the resources on the remote LAN

Why exactly do you need such insane range?

Not going to happen with any sort of 'extender' or card. You'd need to use some kind of point to point wireless link, and you'd need line of sight which means you'd need to erect towers at both sites so you can position the antennas high enough.

If this is about getting an internet connection buy a 4G modem, it's going to be a lot cheaper. If it's about accessing something on the network, then use a VPN.
