Ingenious part! With Restrictions

Packet unpack, download app, LED lamp screw, turning, assign the router password, ready!
Takes exactly 10 minutes and you have another Wi-Fi access has to be opened only on the password of the master access to its netlist.
Of course, the repeater will only have Internet access, if it is built in a place where it receives the signal from the router!
I'm setting up taken immediately adjacent to the Rooter and the lamp then placed at a location in the apartment where they had two more strokes reception.
If you switch off the lamp and sometime again the router assignment is resumed.
Several of these devices are operated in parallel on the same Rooter!
The brightness control over the app manages properly and once selected brightness resumes upon reconnection.
The brightness of the LED lamp is not suitable for an uplight - corresponds to about a 50-watt bulb and has a pleasant light color.

A better solution is inconceivable.

ADDENDUM 1:
I have the equipment now in use for some time and there arises but the occasional lack out.

Still, I stand by it, that I think the solution for awesome.

1. The repeater must be in a place where constantly are at least 2 strips on the signal strength indicator, otherwise you get the message "No internet connection"

2. The Internet is significantly slower than the primary router. A standard page requires almost twice as long to load.

3. The receiving and transmission power of the repeater are relatively low. Therefore, the repeater must be relatively close positioned to the router, which in turn limits the range magnification.

Addendum 2:

I have now set up Amazon Prime video streaming HD movies work properly on a smart TV.
