Disconnecting when right next to router

playing pvp is sometimes stressful for me because i sit next to my router and i disconnect almost every game. Sometimes i get games where i dont dc but when i do dc its always when i am going to win the game. Why does this happen??

Lost server connection twice against the same opponent during two fun battles. The warning screen we get right before entering pvp should be changed from asking if you have a strong connection to “are you ready to roll the dice against our under strengthen server”
So sorry to my opponent.
