Hello,
For context: I have a Telenet contract in Belgium that provides 800 Mbps down and 50 Mbps up. Measured at the modem when I started, I'm more around 600/50, a slight loss but negligible. This modem, located in the basement, is connected to a modem on the first floor via RJ45, with no loss, the latter being connected to a Devolo Magic 2 powerline adapter to distribute the connection throughout the house via a mesh WiFi but also via wired (each module provides WiFi and two RJ45 ports). The house was renovated in 2020, so the electrical network is new.
My issue is as follows: the Devolo Home Network tool indicates that each device has a good throughput: between 800 and 1000 down and between 500 and 1000 up, depending on the module, there are three in the house, one in my office, one in my partner's office (we set up these two offices because of the quarantine) and one in the living room. Yet, the speed measured on a tool like speedtest is constantly between 180 and 250 Mbps down and between 45 and 50 up.
I am trying to understand where this loss comes from and if I can influence it (other than knocking down walls to fully wire the house with RJ45).
What I have already tried:
- Asked the operator if any settings on the modem could be modified
- Modified Devolo settings to switch to full power SISO mode
- Tried all the sockets in each room, disconnected all devices that could interfere with the signal
- Conducted speed tests with and without load on the network to compare values (downloads, streaming, etc.)
The connection is very stable nonetheless, and I realize that my problem is not really a problem as I already have a good speed, it’s just that I'm paying for 800 so I need to know if I should downgrade my subscription in case there is no solution.
Thanks in advance to those who read this!

Hello
A powerline adapter transmits the signal through your electrical network, so if there is a loss, it's the quality of your electrical network that is at fault...
You understand that certain devices also significantly disrupt this speed, especially anything with a motor...
But the only way to achieve a reliable good speed is to use a cable (RJ45) between each device; it may not be convenient or aesthetically pleasing, but it's the ONLY effective way to avoid "losing" speed.
A good RJ45 cable (minimum cat 5e) ensures Gigabit speeds as long as the length doesn't exceed +/- 100m...
If you want to achieve 800 ;-) the only way is to connect your machine "behind" the internet box with a cable!!
See you later
If this answer helped you, a little click on the thumbs up would be great... Resolved is perfect.
Let he who has never opened a user manual throw the first mouse at me ;-) -
Hello
the bandwidth is shared between all the connections of the box, ethernet and wifi, so plugs, TVs, smartphones, tablets, Alexa, air conditioning, heating, etc., etc...
my SFR contract, 1 Gbps in the Grand Est region
I have the Magic2, the best nperf speed on the IPS server, Free, Paris, 40Gbps is 162 down and 251 up within a range of + or - 50
measurements taken over 2 weeks

Mark as resolved if your issue has been solved. I use the informal "tu" with everyone.
Take the time to comment!
A thank you is appreciated.
