Powerline is the last resort in Networking.

Cable > WiFi > Powerline.

In some cases it works (new cables and within 1 circiut) but usually its more headache than anything else.

But dont worrys we all did shit and wonder why it didnt work.

Just be glad you were not called to a datacenter and started tracing all fibers just to realize that a single stupid uplink is 1 gbit instead of 40 gbit
