Hopefully someone can help here. I bought a power line adapter to stabilise my connection for online gaming as I cannot connect directly with an Ethernet cable to the router. This works fantastically well in preventing lag and input delays etc. but every time I connect online using this, FIFA 20 will disconnect me from EA servers. I doubt this is fault with the power line adapter as it works fine with other games such as COD. This problem doesn’t occur when playing the game over WIFI. 
Help with this is much appreciated.
