So I have a gigabit plan, and use tp link AV1000 powerlines to provide wired connection upstairs however I only receive speeds of around 150Mbps, I’m using all cat5e and cat6 ethernet cables, is there any thing I can do to increase speeds or anything I’m missing that could be limiting the speeds?
20m is nothing, doing 500’ for the ‘far’ units at work.
If you are able, you could optimize your setup by having both locations on the same phase in the electrical panel, and if able, same bus connection point. Using circuits that have no gfi plugs , or arc fault breakers is also ideal. You want the units connected directly to the wall, and not anywhere else.
