Even a contracted company that has experience in building WiFi networks in hotels and commercial properties, could - to have to operate without much effort - not figure out what was the cause of our wireless problems. A loan furnished, almost 200 euros more expensive Zyxcel Business Access Point was not able to improve the connection difficulties.
On the recommendation of a friend and after reading the many positive reviews, I then bought this set and expanded with an additional powerline adapters 540E. The 510E adapter is now connected in the basement with the VDSL router (Fritz box 3370) and the two 540E adapters are each connected to the centrally located electrical outlets on the ground and top floor. In addition, an older Fritz box serves as an additional access point in the office, from where the terrace is well covered with. A total of four access points are now distributed relatively evenly throughout the home including the Fritz box in the cellar. All have the same SSID and wireless identical keys.
The establishment of the powerline network was done no problem and including firmware update quickly. After adding the second 540E adapter using the powerline software all components have been detected immediately. Reported transmit and receive rates were in the range between 100 and 160 Mb / s - you can live well. In one case the occupation of a neighboring outlet has brought significantly better data rates; So it is definitely worthwhile time to experiment a bit.
Using the free Android app WiFi Analyzer can be seen that the signal strength everywhere now is at least 75%. Since commissioning of the powerline adapters our WiFi network is running at last stable without disconnections and no dead angle WLAN.
Therefore, I would recommend this set highly enough and forgiving full 5 star rating.
