I don't believe JalenTheEpic is correct. If you're still interested in Xlink, you should know that it's possible to play MHFU with Xlink and an unmodded psp if you have a network adapter that is compatible with Xlink. JalenTheEpic is probably referring to AdhocToUsb, which is a plugin that bypasses the need for a compatible network adapter and lets you use a USB cable instead.
There are many compatible USB adapters, but the only one I have bookmarked is this, so you could start there. If you've got any other questions, feel free to drop me a message.
It's unlikely (but possible) that you have two wireless cards.
If you either don't have two or they aren't compatible (if they're internal cards which came with your computer, there's only a slim chance of them being compatible), then you'll need to get one. There is a short list of compatible adapters on the Xlink Kai website, but I personally suggest just getting a Planex one (they are all compatible, as Planex officially sponsors Xlink Kai). This is the one I use: Planex GW-USNano
