3D Game Man posted a review on the Netgear RangeMax NEXT 802.11n

The 802.11n series of wireless products trumps the 802.11g standards. I was able to run a SpeedTest.net benchmark at 300 feet from the location of the router. I must add that the location was in a residential area inundated with wireless routers and a cellular tower (about six blocks away). The location of the router was located 25' within the home on the first floor. This being the case, we started with the laptop on the front steps of the home (25' from the router). Next, we went to the sidewalk (another ~25'). After the sidewalk, we crossed the street and stood in front of the first home (~150' from router). We then continued to the third house (another 150') to which continuing past this third house resulted in a lost or unreliable connection. From installation to extended range of use, the 802.11n standard has shown itself as worthy of the industry's adoption.
