The package wireless-tools is free software and is in the Trisquel
repository. "firmware-ralink" is non-free software. If you read the
copyright file it says you can only distribute it in binary form without
modification meaning it isn't libre software. We can't recommend you install
that package.
Here is some information that might help you out.
