The problem is the firmware, which is nonfree. You can replace the
wireless card or use a freedom-respecting USB adapter instead. You can
buy this kind of adapters from Tehnoetic or ThinkPenguin which are
certified by FSF to work with free software, or try to find the same
chipset in other adapters available on the market.

You should also add your Intel wifi card to the h-node database and mark
it that it doesn't work with free software, like for this other model:

To elaborate on what Dave_Hunt said, Intel's tendency to cooperate the most with libre software doesn't go beyond its integrated graphics controllers. It's only in that specific category where they are better than other hardware suppliers. Network cards from Intel are hit-and-miss.
