It does have a bit of time before I'm gone behind the operation because it was always spoken in the description of a flashing lamp and has a lamp but still flashed. But as I have done really what is in the description and have pushed the button only once has flashed another light and everything happened as described. So be careful! Plug the device into the power outlet near the router wait briefly, then probably the device is powered up and a lamp has continuous light and a flash. Attention, this is not the flashing lights for the initial configuration. Then press the WPS button on Routder and then press the button on the TP-Link briefly. Only then will flash a further lamp which will flash more quickly and the lights also come on for the signal strength (at all to me, because I was very close to the router) Then it happened very quickly, the route Hatt be connected to the TP-Link and I could infect him further away. He has used a moment, but then he found the wireless and done now for a week its service reliably. Now I'm wondering about whether to order another to extend my wireless into the garden. One device now ranges from the kitchen to the yard into the garage about 20 m 2 building walls there between. It has thus exceeded my expectation for the increase in reach. I hereby like to recommend the device so on.
