A real WiFi Monster

I decided after much back and forth for this AP.
So far I had in addition to my Speedport Router (sent on 2.4 and 5 GHz) even a "small" AP from TP-Link.
I have but it never managed that both devices generate a unified wireless and thus could go a natloser transition from equip.
Short of my spatial conditions: Detached house with a total of 4 floors (house is on a slope and 2 floors are to be regarded in principle as a cellar). Our life takes place mainly in the OG and EC from but a halfway reasonable coverage with Wi-Fi does not hurt: D. We also have a large garden with terrace which is accessible from the first floor of the basement. On the terrace a good cover should be placed in the garden and does a reasonably supply also not hurt.
With my router I have ground and first floor and furnished with the old AP to the first basement and the terrace. This solution was for me but not really satisfactory.

I then ordered this AP and mounted on 2m height in the living room (the living room you look directly into the garden, and in comparison to the router eliminates schonmal a wall facing the garden, which could degrade the signal). Then I use the app Wifi Analyzer (gibts unfortunately only for Android) scanned the wireless channels for 2.4GHz in my area and set the least genutzen channel.
Regarding channels and W-Lan in general there are very nice items at Tomshardware.de knowledge. This helped me imens and I can present this to anyone interested only to my heart.
And now for the result ... why, everything in the world I have not done this much earlier? I have practically not only in all 4! Floors WiFi, but also in the whole garden, the garage until almost up to the road.
I am very excited about the device, because I would have never dared to dream me a result. I came to this manufacturer, because it is promised here that you could connect several AP's problems but that is now no longer necessary for me.
Ah yes, the configuration is done on the PC and is very easy, took so 5 minutes;)
