I worked closely with the engineers at EnGenuis and received the EAP300, EAP150, and ESR350H; well the setup was as easy as possible but the radio download from any system connected to it was about 1.5mbps upload was fine. My cheap Belkin F5D7230-4 (which I had for years in a closet) was able to out preform all the EnGenuis Test equipment I was given. I would highly recommend BROCADE or MOTOROLA AP6511 or AP7131 for any install where you must have an AP, They may not be as easy to setup as the EnGenuis but they work far better. Heck a Netgear WNR2000 with or without dd-wrt will out perform this at half the price.
EAP300 offers a "smoke detector" look, and is a high-powered (up to 29dBm) wireless-n access point / WDS Bridge / WDS AP operates seamlessly in the 2.4GHz frequency spectrum supporting 802.11 b/g/n standard high speed feature. It is the best way to add long range wireless capability to your existing wired network or to add bandwidth to your wireless installation.
EAP300 features high wireless output power and receive sensitivity along with antenna diversity. High output power and high sensitivity extend wireless coverage to reduce the roaming between access points and to provide a reliable wireless connection. It also reduces the total cost of ownership on hardware.
