Wow, you have just discovered a wireless router. Congratulations, that is kinda like that guy who discovered America after Columbus...you know.....ok so I don't remember his name either. There are tons of access points better suited for travel use. They are usually even given the oh so clever name of travel routers. I like the DWL-G730AP which is smaller than a pack of cards and can be powered via usb or wallwart, comes with a little carrying case and can operate as a bridging AP, router or ethernet client bridge.
