Commissioning: connecting to a router Telekom Speedport LTE2 WPS took less than 5 minutes. On the first attempt everything perfect. Repeater then unplugged and elsewhere installed in the house, again no problem.
Reception: Could not be better. Single-family house, in the office router (rear) repeater in the living room (front). Devices are separated by about 5m and 2 walls. Now I have even strong wireless on my terrace and in the garden at least 50m. Before the reception was shaky already in the living room, there was nothing (probably because of a tiled stove is probably well insulated masonry).
Power: Can I not measure it, but it is enough in any case for easy browsing, online video and television and is at least as good as in the past without a repeater. I notice no difference to the PC with LAN connection.
Optics: The repeater is so small and discreet that it does not really stand. The LEDs on the front panel are small and white and not so bright that creates an unwanted disco lighting.
