In September I changed my setup to a new pc and monitor, I also changed the place of my setup. Previously the powerline was plugged into a separate socket and the other stuff was plugged into an extension from another socket. My current setup is a powerline plugged into a socket and onto that powerline plugged in an extension. So my pc and monitor is plugged into the extension coming from the powerline. I noticed this drop when downloading games. Usually, I start downloading multiple games and leaving my pc on for the night, so I turn off my monitor. Yesterday for some reason I checked how much it downloaded and I saw I got double the speed. Before changing my setup I got around 4 MBps but I thought I got around 2.1MBps because of the pandemic. When the monitor is off, I got 4MBps. I tried plugging the monitor to another socket but this also didn't fix the issue. What can I do?
