The TP-Link AV600 works with one pair, but you can connect a third adapter if needed.
The TP-Link AV600 works with one pair, but you can connect a third adapter if needed.
You're using the TL-PA4010 kit and are considering adding a third adapter in another room. Since this info isn't available on TP-Link's website, you may need to check the product manual or contact their support for compatibility details.
The connection between the two adapters operates at 500Mbps, yet it can only translate that into Ethernet at 100Mbps. Since the inputs and outputs are constrained by this lower speed, it doesn't significantly impact your needs. If you have several nodes, theoretically, two pairs could link simultaneously on the same powerline without performance issues.
The devices connected can only reach a maximum speed of 100Mbps under ideal circumstances, which matches the Ethernet port limits mentioned in the product details. When integrating this adapter into an existing AV600 configuration on the same power circuit, it should function properly. Just ensure the new unit is properly paired. Switching to a different power line standard isn't assured to work as described here.
