Good performance, but flaw

I ordered this router, because I want to cover a larger area than with my current router.
The connection quality was better in fact. At the same distance, a higher record has been achieved. Result: about it to the floor, other side of the apartment after all, still about 45 Mbit. My current router (WD MyNet N750) creates about 20 Mbit.

What I unfortunately missing is a guest WLAN. That there are only at the more expensive variant Archer.

Among the flaws which led to the immediate return to the little Testerei:
- The power supply whimpers high frequency (coil?)
- The blue LED are much too bright (means for the router then "way to hell" ;-))

The router should be in the living room under the TV. Unfortunately, a permanent acoustic and visual disturbance will not. The LED I would have to mask off, but the buzzing noise ...

Technically a certainly good product, but not suitable for me. That is why two star deduction.
