Hi I tried doing the above. Just a noob question. I couldn't get all 3 units to be connected at one time.
Connected 2 units (A to router, B to comp), then as advised by instructions book remove B, and connect C (the other comp) by pressing the sync button on A and C. Successful connection between A and C, but when I replug in B, B loses its connection.
Could anyone advise what I should or can do? I have 2 sets of PL1800 and 2 sets of PL600 (but only using 1 now)
I had the same problem when pairing a total of 4 PL1800EP. Had this problem a few times initially until I revert to my previous method of pairing multiple homeplugs (I used a competitor brand before I changed to Sinoeji). What I need to do is after pairing A and B, to leave B in the power-point and powered on and the LAN LED is green, meaning it is in the network. Then I pair C with A. This way A, B and C will be paired, otherwise if B is not seen by A, it will loose pairing with A. Repeating this, my A, B, C and D are all paired.
I also have the same advice for you. Preferably you do not combined with PL600. My experience is that whenever I paired and use a previous AV500, the PL1800EP will show a Red LED in ALL PL1800EP, meaning speed of the entire network is slow, I think below 50 Mbps or there about. Rmove the AV500 and the Red LED in all PL1800EP gone.
