My guess is you're missing the non-free Intel Wi-Fi firmware found in
the package firmware-iwlwifi.  (Debian does not include
non-free-as-in-freedom packages by default.)

To install this package, you must first permit Debian to find and
install non-free packages.  I think you can achieve this with Synaptic
by going to Settings > Repositories, selecting the main or default
repository (it's usually something like debian.org/debian/), and adding
"non-free" (without the quotes) to the "Section(s):" line at the bottom
of the window.  That line should now read "main non-free" or something
like that.  Then click OK.  (Apologies if these instructions are
inaccurate - I don't use Synaptic.)

Once that's done, you should be able to click Reload and then install
the firmware-iwlwifi package.  If not, perhaps you added the "non-free"
text to the wrong repository.

HTH,
