Alright so, I have a TP-Link 500Mbps Powerline adapter kit, and my current TP-Link PCI Express card gets me 82mbps download and 92 upload, which is great. This is what I would get if I plugged an ethernet cable directly from my pc into the router. Problem is, when I use the Powerline adapters, I only get 25 down, and 18 up. I have no idea why this is happening. I thought that Powerline Ethernet should be faster than Wifi no matter what. Am I doing something wrong? I read something online about if the router and powerline adapters are plugged into a different circuit, then there will be a great speed reduction. There is one more outlet in my room that I can try, I will give it a go, but I doubt I will see any differences. The only other thing I saw online was someone saying that they flipped their adapters upside-down, and it doubled their speed. Don't understand how that works, and haven't tried it yet. Please let me know if you know a fix or have any suggestions. Thanks in advance :/
