Review on 🔌 TP-Link AV600 Powerline Ethernet Adapter (TL-PA4010 KIT) - Plug & Play, Power Saving, Nano Powerline Adapter, Expand Home Network with Stable Connections for Enhanced SEO by Non Dollarz

For Ethernet over Power Line to work (at least in theory) with this device, both devices must be on the same circuit. It is mentioned in the product description but I didn't understand what that means because I thought everything will be fine as long as they are in the same house. I think it should be made more prominent because there is a picture of this device being used in a two story house that I wanted to use so I bought it. My router is definitely not on the same circuit (is not controlled by the same circuit breaker) as the second floor room where I needed the ethernet port. Even though these adapters were connected to each other, since they were connected to each other via WiFi and not a power line, the speed I got was the same as over WiFi. So I sent them back. It looks like it's my fault for not reading and understanding the "same circuit" requirement, but I think the pictures the manufacturer took on the Revain product page are misleading because I think that for most of us it is unlikely that rooms on two floors will be connected to the same circuit. The best wireless solution for getting an Ethernet port in a location away from the router seems to be a Wi-Fi mesh network, not these adapters or range extenders.
