I am stuck in this. I own a pair of
TP-Link AV500 Powerline adapters. My home electrical wiring is not the optimal for Powerline, but I must live with it.
The AV500s have a manufacturer-advertised maximum bandwidth of 500Mbps. All my LAN equipment is 1Gbps, including home gateway (no, I don't have 1Gpbs internet access, I am talking about LAN).
I connected my desktop both directly to home gateway and through Powerline using the same 1Gbps cable. When attached
LAN-to-LAN I can see Windows 10 reporting 1Gpbs as expected.
If I set up
LAN-PWL-PWL-LAN from desktop to home gateway I see the following reported speeds.
Windows 10 reports 100Mbps on the LAN adapter, which is connected to Powerline adapter
Gateway reports 500Mbps on its LAN port to twin Powerline adapter
TP-Link's Powerline tool, on the Remote devices page, reports a rate of about 300Mbps, which is quite good according to my non-optimal electric setup.
Question: since I want to communicate with a NAS on the other side of the house that is directly attached to the Gigabit Lan network, why the heck does Windows 10 report only 100Mbps from the LAN port to the Powerline LAN port? I need more speed for internal transfers.
For experimenting these speeds, I have moved the Powerline adapters to the same place in the house and tried to swap them to my like.
I don't think that upgrading to 1Gbps Powerline adapters makes difference (I could try as soon as I have a decent refund policy from my seller)
