The difference likely comes from how your PC and phone handle network traffic and latency. Your wired connection via the TL-PA4010 might be stable but still affected by line noise or distance, while your Wi-Fi setup could be more consistent and closer to the advertised speed. The software reports 300 Mbps, but real-world speeds can vary due to interference, router placement, or bandwidth sharing. You might want to check your router settings or try a different Wi-Fi channel.
Double-check that your device isn't connected to a data network. My dad once made the same error and got lost.
Powerline adapters are often referred to as "wifi over ground wire." If the connection isn't strong, you might encounter excessive interference. Another issue could be that the PC isn't establishing a 1Gbps link to the adapter, which would need Cat5e or Cat6 cabling. I recommend testing an Ethernet cable to the router (for laptops) to compare latency and bandwidth with WiFi. If performance matches, the problem lies with the adapter. If not, the PC might be the source. For desktops or fixed setups, tethering a phone to the PC could be an alternative. It can be frustrating, but if the adapter fails, consider a WiFi card for desktops.
It doesn't convey much beyond that definition of WiFi speed without extra factors. There seems to be no method mentioned to verify PC performance over WiFi and compare it to a wired connection.
