The wirless adapter has convinced me completely. Clamps onto the designated slot device on the rear side and connected via USB. Done. But what is it? He is not my wireless router T-Com Speedport W501V! Once Usb pulled out and again clean-put and all was well. To date, no failures! Absolutely reliable connection! And through the concrete floor! Xbox360 in the living room - 1st floor office router other side! Top accessories section! My absolute buy recommendation!
