after an attempt with the Fritz! Wireless repeater, which, however, did not bring the desired performance, I ordered the Powerline 520E Set and am very satisfied. The installation was very simple (plug insert runs). The result is just great, now I can on my TV, which is one level lower than the router, look smooth videos from the library. The consultation this came by the way of AVM after I nchgefragt for the repeater.
