I ordered a pair of Power line (PLC) (picture) TP-LINK TL-PA551KIT adapters. Intended use would be replacing Wi-Fi, therefore reducing latency and packet loss and enabling features like VoIP and multicast for IPTV streaming. Also it would not spoil the overall look in the apartment running cables under the ceiling to each room. Maximum classification is 500Mbps/s data transmission with a GigE port. I wonder if it will work at all. (update) There seems to be an issue on the electrical wireing in the apartment, which prevents the adapters to be used. In case anyone would want to buy off these adapters, you can contact me about it.
