I have set up a powerline network using the TP-LINK AV1300 Gigabit Passthrough Powerline Starter Kit which runs into a switch with a philips hue bridge and a ethernet cable to my computer. However since setting this up it has caused worse performance of my router (it now has a lower bandwith). Does anyone know why it will cause worse performance of my WiFi? And if there is a way to fix this?
