While I have done this I'm a bit advance in that I wrote a NAT router app over a decade ago. So while we know it is possible the problem is that the setup is advanced and some folk will falter or try to do this without a router.
So when I do this I use a router without the ISP feed to create the WLAN and LAN with the printer on that W/LAN. Then I've good. The setup is going to be rough on some as there is no document that describes every step.
They may be right that some folk can't do this.
I have two laptops, both running Vista and want to get a wireless printer to use with them. I do not have a wired ISP; I get my internet through a laptop connect card. I've been told all I need is a wireless printer; I've been told I need a wireless printer and a router; and I've been told I cannot do it without an ISP (i.e., AT&T, Roadrunner, etc.). Which is correct?
