The first and the most important thing we have to check is to make sure all the wires or connections are set properly. We have to check the power cable of Netgear wireless range extender whether its properly connected or not. IF not, we have to make it right. IF its connected properly then, we have to check the status of power LED that is what is the color of power LED. Is it red, green or amber? If the power LED would be solid green on the Netgear wireless range extender, it would mean the hardware IS working fine. http://www.mywifiext-net.com/
