AirPort Graphite direct to LW 320

Hi all. I know this is dope-level, but it hasn't been working for me.

For some time, I used my graphite AirPort Base Station to share the
dialup modem connection and an Ethernet network on a little hub. I have
an LW 320 with an iPrint adapter. No problems.

Now I'm sans hub, and the rest of what was on that network. I need to
connect my LW 320 (with iPrint) right to the Base Station (and still
use the dialup modem). AFAIK, this should only require a crossover
cable from the iprint to the Base Station.

However, it just ain't workin for me. I've done all the Apply Now and
Setup stuff I can think of. The modem's fine, and the printer's fine if
I connect it directly to the computer. Is there something I'm
missing...?
