With this device, the expansion of a wireless network by two floor ceiling manages fine. The facility decreased slightly from equip and is well described. The existing WPA2 encryption could be taken and a MAC filtering is also possible. The radio range is greater than that of my Speedport W500 whose scope should be enlarged yes. The repeater has a pleasant appearance, makes no noise, does not develop any appreciable heat and has a German Setup Wizard. The real power measured is an average of 5.5 W, or about 11.00 EUR annual energy consumption in all-round operation. Who is too much, it switches on from lying on the back switch and is completed with a fraction of the cost. Overall I am very satisfied with the purchase. Supplement: the concealment of the SSID has lifted in the Speedport W500 menu and the repeater mode to be activated.
