The additional Ethernet port is a big plus if you want to connect not-Fi enabled devices over a LAN hub. Now have a multimedia player, my TechniSat Digital ISIO C, the VideoWeb TV and an older Archos TV + for US video streams from Revision3, CNET and the German media centers connected via the LAN hub and is for the PS3 is the Wi-Fi signal from previously 90 % now increased to 100%, which invites Amazon Prime videos even faster. I'm excited.
I would like to note, however, that the blue ring lights up relatively bright lights, which is why this Repeater could interfere in the bedroom rather, if it is not attached obscured. For me, it put on the wall next to the housing wall and does not bother. Earned five stars because both TP-Link devices at once perfectly worked together.
