Plugged near modem, WPS button on the repeater, WPS button on the modem and it sparks!
After plugged in the living room - and he radioed!
Tentatively separated by switchable power strip from power, turned back on - he quickly finds again the power.
LAN connection tested properly.
After half an hour I was happy and content.
Out of curiosity I wanted to even look at the user interface via web browser, just did not go, no connection - error message.
Online Support interviewed, found solution - and now goes also.
Tip: Web Broser the wireless modem access, IP address of the repeater Remember, this type in the command line - good day!
Oh, I bought it to me, since my new AV Receiver only LAN port has (to Denon: 700 EUR no great shakes of you !!! Real) and must be incorporated into the network.
My BluRay players benefited from it, he had previously found arge problem in the network, thanks to bad wireless module, is now top! On notebook there are no advantages or disadvantages, transmission speed about 120 Mbit / sec whether switched on or off.
So what more could you want - full marks
