^^^ I said above onemesh doesn't work with access point mode. I mean ap mode on the range extenders. Onemesh will work if you have a extender connected to a tp link access point.@Chickenslyrr

@Macro8898 as stated above you can't extend 3 to each other. My advice here would be to buy tp link powerline Ethernet adapter and connect it to your router and the other half put at 2nd farthest...
