Customer Review

The Powerline adapter TL-PA4020 of TP-Link have brought in the home use about what was to be expected.
As already described by other users, you should not be blinded by the high data rate as is specified by the manufacturer, because the LAN port brings only Fast Ethernet.

According to the manufacturer is encrypted with AES128 in transit, please indicate nil.

Were realistically achievable and are mE data rates between 3.5 6 MB / s, the latter size when. Consistently sockets, distribution boxes instead chooses a mounting location and having the wiring on the floor or in the house no special features

Interference can be all electrical appliances that are in particular the same or upstream ground distribution level, while taking significant impact on the transmission rate.

Downloadable on the website of the manufacturer (and on CD) is a management tool for Windows (and Mac), which allows to access and adjust some data directly connected and properties under Network Powerline adapter. Among others, there, with known passwords of the adapters (standing at the back of the adapter and can not be changed), they are centrally managed. Whereby management limited to QoS and award of the network name and a few other points.

In Management Tool to connect via quality of LAN cable connected directly to the other Powerline adapters appears. This should be regarded as approximate guideline. The maximum achievable connection size was in own tests 337Mb / s, according to tool, and this meant two Powerline adapter on the same bus bar. This has been achieved here by myself a transfer rate of 11.8 MB / s download.
In various experiments with cascaded distribution boxes and powered-on electrical equipment, the considerable sensitivity could be against interferers such as monitors, computers, receivers, etc. reproduced. Even better distribution boxes with filters and surge protection, etc., may significantly restrict the connection quality. Billigstverteilerdosen brand Wühlkiste construction market, however, almost no negative impact on the connection quality have shown.

Here are a few recorded data via. Download Client Server (without any claim to accuracy) for transmitting Size: 337 Mb / s -> 11.8 MB / s, 270 Mb / s -> 11.3 MB / s, 242Mb / s -> 8.2 MB / s, 170 Mb / s -> 6.9 MB / s, 130 Mb / s -> 6MB / s, 80Mb / s -> 3.5MB / s.

Oddly, despite relatively high Displayed transfer rates (> Fast Ethernet), the actual transmission rates have already fallen. Maybe two channels (Full-duplex) are opened for the operation that bisect regardless of amount of data transferred, the actual bandwidth for a download (Priority use in only one direction) again. To what extent several powerline adapters that among themselves the bandwidth around forming may also adversely affect perk, I have not tested.

In two different phases (between the used sockets) was to determine that the transfer rates specified abruptly fell to me to below 100 Mb / s and less and additionally the displayed values ​​were significantly undercut by actual again, for example: 98 Mb / s - > 2.5 MB / s, 78 Mb / s -> 2.0 MB / s, 64 Mb / s -> 1.5 MB / s, 56 Mb / s -> 1.2 MB / s. Below displayed 60 Mb / s burst transfer rates in this scenario, the occasionally completely together.

In addition, I realized that the connection strength relatively strong (about 25%) may vary from time to time (despite supposedly the same experimental set-up).

The latency (measured via SMTP / ping) is approx 3ms in poorer connection quality also some distinct prick interspersed upward observed.

The involvement of a third Powerline adapter in the composite was unproblematic to accomplish (a button).

Conclusion:
For my purposes, so transmission of High Definition video to your TV and connecting a game console, and the use of Internet content with my specific house wiring sufficient.

The management is rudimentary, quick connection via a button worked relatively unproblematic.
