I have a new R300 range extender on my verizon wireless network using  a FIOS G1100 router. The extender is connected to the network, and the TP-Link app tells me I have good signal strength and location. Llights indicate this as well.  However, I have no clients connected, according to the app, and there are at least three devices within 10 feet of the extender.  The app ltells me my router does not support OneMesh.  Did I purchase an incompatible device, or is there a way to force the connection?
