Oh, so you're saying the smaller deb without wesside-ng works, but the bigger one doesn't? I'll try to confirm that.
-edit-
i just used dpkg to install the bigger deb, it gave a warning that it's downgrading (my bad) but it seems to work fine still. Now I see the file names are a bit different, you were using the one without wesside anyways. My iw version is 0.9.19 btw.
