This product (854RE) as shown in the table does not have ethernet jack. It has been updated with the latest firmware (at 15.01.2015) which appears to significantly improve its performance. This does not prevent it from doing its job well: the configuration wps is done quickly and simply (it copies the id and pwd network and becomes transparent replica of the main router). Without wps, it must go through the web interface of the repeater, you only have to find his address in the client list of the main router or connect with dlinkrepeater.net if the computer is connected directly to the repeater. Its performance is correct: with a dual-band wireless n router, with a computer (wifi ac intel7260) in the same place, the flows amounted to 8MB / s (negotiation at 162Mb / s, 2 meters from the router, the flows amounted to 16MB / s), the repeater is not better than 1.2MB / s (54Mb to negotiation / s). It allows comfortable access to the internet stream, but for more substantial transfers (local or online), it is insufficient. The performance might be much better if the antennas can be rotated 90 ° (flow rates have doubled with the computer by turning). Its design does not allow this operation.
