Re: [Trisquel-users] Libre/Open Source Firmware M.2 Wifi Card?

[publiclewdness]

I would go with one from Think penguin if they have one that is the right  
size for you. They cost more but are actually tested with Trisquel where many  
places don't so if you want to "avoid experimenting" they would be a great  
option.
