I've recently moved back into my parents house and so now have the playstation in my bedroom whereas before in my old house it was downstairs in my living room plugged straight into my sky router (i think thats what its called). Now with it being in my bedroom i have to play online via wi-fi mode which is alright for going on the ps store but when i come to play a game on fifa say then it lags terribly. So is there any way i can play games on fifa without moving the router or moving my playstation and if so how much would the equipment cost?
