Limiting powerline speed to 100mbps
Limiting powerline speed to 100mbps
I own the TP-LINK 2000Mbps TL-PA9020PKIT. In the UK my connection has always been slower than in many other countries, usually around 70mbps down and 20mbps up. The powerline adapters perform as fast as if I were connected directly to a network switch. Recently we upgraded to 1000Mbps down and 130mbps up, but the powerline adapter caps at about 120mbps down and 90mbps up. Others with similar adapters are reporting speeds they paid for. I’ve noticed that gigabit speeds are rare, yet people with similar setups seem to achieve much higher performance.
Consider moving the file transfer to devices right behind the power line instead of using a speed test. Then connect a device directly to your modem to check the real speed. Most probably the powerline’s capacity is limited by your home wiring and any interference. If your house has outdated wiring or you’re far from the source, performance will drop.
I've struggled a lot with Powerline setups. It's at least an improvement over nothing, but wireless tends to work much more reliably. From what I remember, using a Powerline adapter inside an extension cord or power strip really drops performance. There might be factors to consider... Wishing you success!
I connect straight and get 1050mbps down. It's a brand new house, so the wiring is top-notch. Usually I'd also use an access point linked to the powerline adapter, but with the speeds dropping on the adapter it's not working as well at home. I've unplugged it to see if that helps. I haven't had any problems before, but since FTTP came in, performance has dropped. I still use my gaming PC, which is why I upgraded.
Powerline faces several challenges, with the most significant being increased interference compared to a few years ago. The modern power company that relies on digital signals on the cable has replaced the old pulse clocks, resulting in many more signals in the air. Your wires lack twisting or shielding, making them like large antennas that capture various unwanted signals your adapter must filter out. You can observe this in a signal/noise section—perhaps a signal strength of 80% with 60% noise leaves only 20% for the usable bandwidth.
Powerline has several limitations that affect performance. Results can differ widely due to individual wiring setups and interference sources. Factors like new electrical installations, insulation quality, circuit load, nearby appliances, and additional protection devices all play a role. Test the adapters in the same room, ideally on the same circuit, with other devices turned off. Run a speed test and gradually restore devices to observe how performance changes. The issue isn’t a faulty adapter but its effort to deliver the strongest possible signal under current conditions.
