The marketing team promoting network equipment often spreads misinformation or deliberately guides people astray. When they claim speeds by simply adding transmit and receive rates together, they overlook key differences. Ethernet can actually achieve both sending and receiving at the same time, unlike Wi-Fi, powerline, or other systems that operate in half-duplex mode, allowing only one device to transmit at a time. This lack of control causes data overlap and corruption.
It’s difficult to determine the exact bandwidth, but if the powerline connection reports only 166 Mbps, the real capacity is likely half of that. Even when advertised as 1000 Mbps, the actual speed users experience is around 130 Mbps—just over a tenth of the claimed rate.
Changing cables probably won’t help much. Router statuses often show 1 Gbps for powerline connections, but this depends on the router’s interpretation. You might also notice visual cues like lights or color changes indicating the port is active.
What really occurs is data moving between the router and the powerline device at 1 Gbps, waiting in a buffer to be transferred via powerline protocols over the electrical wire. Ethernet behaves this way—it either operates at full speed or not at all. What you observe are averaged speeds over short periods, managed by software.
Consider replacing cables only if the connection drops to 100 Mbps instead of maintaining 1 Gbps. This is the actual speed shown in status updates, not the average throughput. Ethernet typically runs at 1 Gbps or 100 Mbps, with newer versions supporting speeds like 2.5 Gbps or 10 Gbps.
I just wanted to mention in the US how 240v can be generated from two hot lines that are out of phase, meaning powerline devices won’t work well if they’re on separate lines unless a 240V appliance like a heater or EVSE is actually running to connect them. There are phase coupler gadgets that let the lines talk to each other when no device is using power.
In Germany, it’s typical for 3-phase wiring to be installed so that the 230v at any outlet can come from any one line, making communication with powerline units on the other two difficult. If you’re in Spain, you probably have just one hot 230v wire, which should avoid this issue, though their powerline gear tends to underperform.
I’ve often considered it might be feasible to link at 10/100 speeds using four coathangers, but reaching 1000Mbps over just two lines and over long distances seems like a stretch. Without any interference, house wiring can handle most RF noise, so the closer you are, the better.
Power line adapter protocols might not be worth the extra cost. G.hn behaves differently compared to AV, and AV2000 is more recent than AV1000, which could affect data transfer speeds. In my experience, I'm using a TL-PA9020P across our house circuits and it's worked well. It's mainly used for connecting TVs, so I haven't pushed it beyond 55-65Mbps.
Understood, I’ll go with Cat5E. I need to buy a new cable since the one included is too short.
By the way, I’m not sure what you meant by "people like you," but I don’t have much experience with hardware.
This is my router. As mentioned earlier, I require a longer cable on one end because the provided one is quite short.
I’m located in the Chilean countryside where power supply is unreliable. We experience power outages almost once a week due to accidents that knock down poles or, in winter, strong winds that damage trees along the lines.
That’s my situation.
Voltage: 220V (single-phase, line-to-neutral) – Some older setups might still use 230V or 240V, but 220V is now the standard.
Frequency: 50Hz
Wiring: Phase (Hot/Live) + Neutral + Ground
Have you or anyone else tried different brands? I’m using this because my internet reaches my office and I need to extend it to my house, which is about 40 meters away. The Wi-Fi signal from the router is very weak, and after trying a Wi-Fi booster and Powerline, I decided to go with Powerline.
It seems there might not be any coax lines connecting the two devices. MoCA could be the optimal option in this case. For G.hn adapters, Zyxel would be a good choice if you're considering an alternative powerline networking protocol: PLA6456. A high-power unit or a point-to-point setup would likely be necessary for WiFi to achieve better performance compared to what you're experiencing now.
