Ron,
Well, first I think to comment on a machine in that much of a negative way when someone else has it, can only make them feel bad at best. I would maybe message Eric, show him the reviews and ask him his take.
Any machine that is networkable, will network on a wireless or a wired network, BUT the machine (fax) would have to have a wireless network card/print server or whatever. My suggestion on these is to research what you want and then contact the distributor or manufacturer and verify with them it will do what you want. Get it in writing and make sure you can return it if it does not do what you want it to do.
You can also mix wired and wireless.
I do know that Eric is very computer literate and network savvy, and I would trust him if he says that his fax machine is a good one.
