[Trisquel-users] Re : Wifi card for laptop

[lcerf]

You can... if the manufacturer of the laptop does not impose unjust hardware  
DRMs (to force you to replace the card with one it "approves"... through a  
business deal).  Apple, Dell, HP, Lenovo, Sony and Toshiba are known to  
impose such DRMs on Wifi cards.  Not all their laptops are affected though.

http://libre.thinkpenguin.com and https://tehnoetic.com are the only two  
vendors that guarantee that 100% free Linux kernels (no proprietary firmware  
in particular) properly drive all the hardware they sell (including internal  
Wifi cards).  They both internationally ship.
