Re: [Trisquel-users] Cannot configure connection settings.

It is unfortunately possible that your wireless card may require non-free  
firmware to work.  Should that be the case, it wouldn't work with Trisquel  
which is based on the Linux-libre kernel.

Can you run lspci in a terminal and post the result here so that we can  
understand which wireless card you're using?

Thanks!
