Same here, i already tried configure it to replace the "lag type of DIR-615" but still cannot. I call TM-Unifi for support as usual is useless . Also do a bit of research for several TP-Link model that support TM Unifi. Then I also call TP-Link Malaysian Support & Main line Support to help me get the idea. I ask about firmware maybe need to update or have configuration that can work with the TL-WR2543ND and TM Unifi. They said to me; Wait maybe several days or month , their team still work on the new firmware for this model to use for TM Unifi. I hope KLSEET can post this model to be tested with TM-Unifi. Cant waittttt..wanted to try really bad..pleaseeee.. Help..me!! i..need the guidance..
