ChangsITSupport wrote It depends which circuits are connected to which plug sockets in the house. I had powerline adapters like those and I found them to be much worse then wired ethernet, plus they wouldn't work in most sockets in my house. Depending on where your router is, a WiFi adapter may be a better choice.

Worth looking at the adapters, at least. I use them and I still get very fast speeds with them. My router is only upstairs a bit, so I could have probably ran an ethernet cable through the ceiling, but felt like it was a waste of time lel.

OP-Ethernet cable through the ceiling is another option, powerline adapters are 2nd best IMO, worth looking in to them at the very least.
