Do the math, and you'll see that 85 Mbps is not unreasonable in a best case scenario with Powerline.īut wait, there's more! The physical layer (the copper wire itself) is also a source of electromagnetic interference. And this is all before we get to the application protocol itself and its overhead ( e.g., HTTP headers or SMB headers).īetween the limitations of the medium itself and the protocol overhead, this is why your observed or "real world" throughput is far less than the advertised speeds. If your traffic is being transmitted using TCP, there's additional error detection, packet ordering information encapsulated in the TCP headers. Encapsulated within an Ethernet frame is an IP packet, which has more header overhead. Ethernet frames at layer 2 have overhead for source and destination MACs, as well as a few other bytes used for other purposes (e.g. And remember, this is your best case scenario. When you further factor in that the two devices cannot talk at the same time, your available throughput is halved again to 250 Mbps per device (it's even worse with multiple powerline adatpers). However, when you factor in that a device can only send or receive, but not both, the available throughput drops by half to about 500 Mbps. In the real world, with two powerline adapters on the same circuit and a very short run of high-quality romex wire, you might be able to stream at 1,000 Mbps from one to the other. This fails to take into account a number of factors, such as protocol overhead, the fact the powerline is a half-duplex medium (you can transmit, or receive, but not do both at the same time) and uses a shared broadcast domain (only one adapter is allowed to send at a time). In other words, it's measuring how many bits can physically move across the wire.
The TP-Link utility is also correct, but it's measuring throughput at the physical layer (layer 1) of the OSI model. However, the other side of the adapter has far less throughput.

The RJ-45 port is a gigabit port and that's what the Windows device is connected to. Windows is correct when it says it is negotiating a 1Gbps connection. I might have been able to get more, but the adapters were on opposite sides of the house, so it was a pretty long run. As an example, I used AV2000 powerline adapters (theoretically 1 GBps) in a "best case scenario" (adapters were on same circuit of wire with no extra sources of line noise) and would only get about 100Mbps - 125 Mbps actual throughput. You're lucky to get 85-100 Mbps realworld throughput with Powerline. u/RoweDent created this awesome resource on network theory u/tht1kidd_ has created a suggestion post regarding information everyone needs to provide when asking a question about their network There have been some excellent guides written in this sub, and we're always looking for more!
