I'm glad that it worked, but were not finished now. Both of the kernels I
proposed you to install comes from the official Trisquel repositories. Now
that you have got a working wireless connection, open up a new Terminal
window, then type:
sudo apt-get install linux-image-generic-lts-belenos
sudo apt-get remove linux-image-generic linux-image-3.2*
The first command installs a meta-package for the 3.5 kernel series, that
will ensure the installation of future kernel updates. The second one removes
this functionality for the older 3.2 kernel series, and also the kernel
itself, since you doesn't require it anymore, and because of the
non-functional network connection it is useless anyway.
