Intel Corporation Centrino Wireless-N 2200

Hey,
I found that my wireless network contorller does not work on linux-libre kernel. this is the relevant lspci line:
03:00.0 Network controller: Intel Corporation Centrino Wireless-N 2200 (rev c4)
Now I wonder:
1. How is this possible since this an Intel wireless chipset? I heared that Intel does publish free drivers for it's hardware.
and
2. How can I fix that? so I can run linux-libre kernel on my Lenevo ThinkPad T430.

1) The Intel integrated graphics is supported by libre software.
2) you can get a wifi radio such as the USB offerings from

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.

I don't believe any of them are free software friendly actually. I might be mistaken about older cards though.
Hm, I felt sure my old laptop had an Intel wireless card. Not sure where I got that idea from, though, it clearly has a Realtek card, looking back at the h-node entry I made for it.[1]

Yea- all the 802.11n cards except some broadcom and atheros are dependent on non-free firmware. The newer 802.11ac atheros are also dependent on non-free firmware unfortunately. Hopefully we'll get them to release the code like they've done for the 802.11n twice now, but it's a lot of work.
Thus far they've been uncooperative with 802.11ac.
On a side note, you might be interested in the recent discussion on a
similar subject at the FSF-Debian collaboration list:
