I have a Brother printer (HL-2240) that doesn't have built-in wifi. I would like to re-locate this unit into another room--away from the computer it is currently connected to. The only connection port on it is USB. What gadget(s) do I need to connect this printer wirelessly to my main computer, some sort of access point or something? I have a wifi router that I use on occasion to link to either of two other computers, each with their own wifi adapter. Networking is my weak area, so I would appreciate anyone's input here. I know I could simply get a wifi-enabled printer, but want to know of an alternative (a device I could hook up to the printer).
