Purpose of the device: HD streaming in the home network (watching movies from the HDD VU + Duo2 downstairs with VU + Ultimo in the basement). WLAN with the Fritz box was too weak (gross 80 MBit / s). 1st attempt CSL PowerLine 500: extreme jerkiness ! 2nd attempt Fritz Powerline 500 / 520E: slight judder; Gross rates: Duo2 = 130-140 / 60-97 Mbit / s (send / receive) Ultimo in the basement = 70-98 / 150-161 Mbit / s 3. attempt Devolo 650+: contrary to expectations properly! Gross rates between 200 and 300 Mbit / s, no shocks
No idea why Fritz was not sufficient. The data rate (net: about 1/3 of gross rates) was supposed to be enough in theory. This is a relatively new house with only 1 meter, but probably differnet. Phases. And the devolo have actually managed rauszuquetschen the missing remainder of the power lines. I would not have believed it before, and I really did not want to invest so much money, but it is (for me) the only clean working solution.
