Bought this to act as an extension for our wifi, having already used Homeplug for fixed connections before. Works very easily IF you have worked out what you are doing. Instructions very technical and in poor English. However, a quick trawl of the net helped . Worked first time by I) setting DCHP off ii) setting the SSID, password and channel to be the same as my router. Very straightforward, took a couple of minutes once I had read up. Would have been 5 stars with better instructions.
