I suggest try swapping the cable over to the LAN port of every secondary node, like Dave's digram above. If you have any wired device such as a set top box attached to a secondary node, you can plug the device in the WAN port instead.
Technically, the LAN and WAN ports of the secondary nodes should behave the same. For example, when a secondary node wirelessly connects to the primary node, both the WAN and LAN ports on the secondary node can be connected to wired devices. However, based on what Dave discovered above, Tenda does the backhaul over the LAN ports when two or more secondary nodes are wired to the primary node.
It appears that connecting a secondary node WAN port to the primary node LAN port only works when daisy chaining them, i.e. Primary node LAN to Secondary node WAN, then its LAN connects to the Third node WAN and so on. This may explain why only one of your secondary nodes shows a wired connection when connecting their WAN ports all to the primary node's LAN port with a network switch.
