Good reception with D-Link router

I have the repeater now about 2 weeks, and it works very gut.Mit my router goes down to the 1st floor and with the Reapeter in the 2.Etage.Da I had hardly nichts.Nun full reception.
The device according to the manual is a bit fehlerhaft.Mit Win 7.Es missing 2 steps to get to the place where you can change a few data muss.Aber if you look a little familiar go.
