I don't understand my Powerline network speeds.
I have the TL-WPA9610 kit, one device connected next to my router and then the WIFI one in the lounge downstairs. I also have 1 x TL-PA9020P connected in my office. Theoretical speed for all devices is 2000Mbps.
On the TP-PLC app I see all devices OK. If I look from the router's perspective I see a reported data rate of around 500Mbps to both the office and lounge.
However, when running internet speed tests I never get more than 40-50Mbps. If I'm connected over ethernet to the router, I get the full 350Mbps line speed. This is the same on both the lounge and office, and is the same whether I have either one or both devices connected.
I realise powerline won't give me the theoretical speeds, but I'm only getting 10% of the reported speed, less than 3% of the theoretical.
What's going on?
