I have a few TL-4015P PLC at home and recently purchased a smart TV with an ethernet connection (wifi at home is terrible). The problem is those 4015P homeplugs have only one ethernet port that I need for my set top box. So I bought a TL-4020P Kit (with 2 ethernet ports, 1 for the box and one for the TV set).
Are these two models compatible with each other? (note that the 4015 does not have a "pair" button). It seems not to be working, although this is supposed to be plug&play...
Any help will be appreciated here. Cheers!
