The first step is getting the USB wireless to work, which I haven't been
able to yet. My research
yesterday indicates I need the r8712u module, which isn't available in
the 3.4.4-voyage kernel.
I've really been hoping to avoid building a new kernel...

When I plug the Rosewill in, nothing appears in dmesg. This excerpt is
from when I manually
insert the rtl8192cu module, which I thought was what I needed, but I no
longer think that's true:

This is the heart of my current problem; no wireless interfaces:
