HIGH GAIN antennas that point in no particular direction. Suck on that, High School electronics teacher!

The reviews aren't exactly flattering with regards to workingness. For about the same money, you could have a well regarded Linksys/Cisco AP that supports repeating. If you can drag an ether to your destination, just do that. Set gateway of your extension AP to the main AP (192.1611), give it a unique IP addy (192.161254), and a unique SSID. Turn off DHCP/DNS/WAN, plug the cable into the HUB port (forget the internet upstream port), and try it out. You'll probably lose access to this APs admin page a few times until you get the setup procedure right, take notes along the way, reset, and try again. Once it's all working, set the SSID (and password) to the same as the master, and you should have semi-graceful transition with all your gadgets.

I have used these numerous times and never had a problem with them, They work great if you set them up correctly and use WPA-PSK (TKIP) in both units (Router and extender) All other security options seem to fail and drop....

As PEN_SQ said, Just daisy chain routers and you will have no problem, But these HWREN1 bridges/Extenders are for buildings where you cant daisy chain or run cables...

pen_sq - google dipole antenna and gain. Yes there can be high gain: the 'ideal' sphere of a 0 dB antenna turns more and more into a cylinder as the gain goes up (top and bottom of the sphere are reduced, power goes into horizontal spread). You do not want a high gain dipole if you need to cover a couple of floors.

No idea how well this router works.
