University prefers an Intel-based wireless adapter if possible

Sure, it's a Wi-Fi card that you can remove to insert another one.

If you haven't purchased the laptop buy one that comes with an Intel Wi-Fi adapter. 

You would have to take the notebook apart, remove the Realtek Wi-Fi adapter and install the Intel one.

It isn't the easiest thing to do either.

Here is the link to the service teardown video for the model series which has the Wi-Fi adapter removal and replacement procedure.

I have not purchased anything yet. I'm looking for something that already has built in what the university is suggesting.

That model is not sold with an Intel Wi-Fi card; you'll need to look for another model.

[Momof598]

Might you be able to suggest some models?

It depends on your budget; in general, models that use Intel Wi-Fi cards are more expensive. The following model is marketed with Intel Wi-Fi, but you should always ask the salesperson, because it may also be equipped with Realtek.
