A notable improvement, however, is the extra noise-filtering outlet included on the front of the adapter included in response to criticism that previous Netgear adapters obstructed any other outlets near the one they were plugged into because of their size. Other than that, the idea is the same: plug one adapter into the wall and into a router and put the other anywhere in the house, where it offers a single Ethernet port for any Ethernet-enabled devices to be connected. Once connected, these devices (such as HDTVs, Blu-Ray, gaming consoles, computers or laptops) can share documents, storage, games, or HD videos across a high speed connection of 200 mbps, with 128-bit AES security encryption that can be set up with the press of a button. Note that one adapter is needed per device because they only have a single Ethernet port. The XAV2501 includes an Ethernet cable, Setup CD and 1 year warranty and is compatible with Mac OS X and Windows 2000/XP/Vista.
