Summary: This completely did not work for me. I have lots of networking experience and spent hours trying to figure out a reason why it wouldn't work. I then spent hours more going through the (poor) troubleshooting and customer service solutions to no avail.
Summary: I ordered this item partly because the Tech Specs stated: "Ports 5 x 10/100 Fast Ethernet Switch" However, upon opening the package, and voiding the possibility of return, I discovered only one LAN connection! The product description needs to be changed.
Summary: After a lot of internet search, I'm finally able to make it to work. The documentation that comes with it is very poor. Essentially you connect the port 5 of Edimax to one of the free ports of your existing wireless router.
Summary: Works great as a range extender for your existing wireless router. I thought it cut out every once in a while, but it turns out it was the fault of my main router. Now that I have a new router installed, the range extender works perfectly.
