Unable to route between 2nd and 3rd TL-PA711
Hi
Recently bought two sets of the TL-PA711 KIT to set up points in new house, one for internet connection (#a) and then 3 for other rooms in the house (#b, #c, #d).
I've set up the powerline adapters in #b and #c. Full green lights, internet connection available to both as expected.
It is possible to ping the devices in #b and #c from room #a, but the devices in #b and #c can't ping each other.
The TP Link PLC utility tells me I'm getting between 150-300Mbps from #a to both #b and to #c. However on the route between #b and #c there is just a question mark, suggesting to me they can't see each other for some reason.
I haven't yet been able set up room #d to see if I get a different result.
Do I need to do anything in particular to make these route appropriately? I would have expected them to route back to #a and then hop to the other powerline adapter.
