N USB Wireless High series
This adapter is a good product with a few limitations.
-When plugged into the USB port, it hangs down because it is so heavy. If something is not used to prop it up so it returns to a 90 degree angle, it will slip out of the port from time to time. Also, I worry that the weight will ruin the port by bending the metal. You will have to designate something to prop it up while in use.
-I use this to boost the signal from my media player to the computer. The only way it will boost the signal is if there is a direct and clear path between the player and the modem. The modem can not be in another room, behind a closed door, or even behind a room divider screen. The signal will become choppy and that is no good for streaming media.
If you can live with these limitations, it is a fantastic tool for the price.
