Brand new Asus RP-AC68U Repeater. Bought wrong by mistakes. $400 for each. Interested? Please send private message. Can meet at HK island line MTR station. The RP-AC68U wireless repeater has powerful internal MIMO antennas that help to eliminate signal dead zones and improve the coverage of any existing wireless router. It works as a repeater, which means it can extend wireless networking to every corner of the home — even to those difficult, hard-to-reach spots.
