I have the router for two weeks now, very good device , everything works as i want and the speed is very good.
BUT

the Transmit Power is set on high and to be honest its not what i expected, poor to say.
i have a dir-655 as repeater and they both send out same wifi signal , sometimes the dir-655 sends further away.
i also have a netgear wndr4500 , also top model, and that one sends out WAY much further out then the 857
really the netgear sends out to the back of my garden around 50 meters and more ,
dlink 857 drops when i set my foot outside

dlink 655 sends also out till end of garden

Transmit Power is on high , i tested all 3 routers on the exect same spot and dir-857 has fastest speed but lowest range.
i would like to know how that comes

because thats the only thing that annoys me about the router
