ok, so ive decided to go with the linksys router. going with b, because everyone's laptops in the house already has b cards. now, as for the desktop, should i go with the pci or the usb? any difference at all? as for sharing printers, they can still be shared on the network through one computer right? (for example i dont have to purchase a printer server to access it from other computer?) and by using a router, am i sharing one IP? because we're running two ips with the current wired network.
