I have a Lenovo Thinkpad T440 which I was looking to install FreeBSD on. The laptop has an Intel Dual Band Wireless-AC 7260 chip which doesn’t seem to be supported (yet).

On my travels, researching whether I might need to install an available driver or some such thing, I've come across some terms which I presume are acronyms:

  • iwa
  • iwl
  • iwm
  • iwn

My presumption is that iw stands for something like Intel Wireless? Is that correct and what is the letter at the end?

I thought perhaps it had something to do with wireless standards, like 802.11a/b/c/n/ac/etc. but that doesn’t seem to be the case.

Neither does it seem to be the case that iwa is older than iwn as I’ve found someone working on the 7260 under a git repo titled iwa and have found a man page for iwn which doesn’t mention the 7260, but does mention older models (I think).

  • Could you use the word in a sentence? :) Some example would be nice were these terms are used. But I think they are all driver names and that iwa is a new driver that is currently developed. – Raphael Ahrens Sep 27 '15 at 5:40

These are different driver names for different devices. The iwn man page and the iwi man page document these drivers. The iwa driver you found just might work, but be aware that getting it built isn't trivial and will take some work.

  • Oh, I think the i is for intel and w is for wireless, after that I think it's somewhat arbitrary. – Steve Wills Sep 27 '15 at 23:37
