No, no. Not at all. First of all, before entering the game; you set up a connection. Then when you're in the game, you go to a Pokécenter (doesn't matter which) and then go down the stairs, and talk to the lady in the middle. She'll ask if you want to go to Wi-Fi room and save you game, you say yes at both and then you'll be transfered to the Wi-Fi room. There'll be a big screen at the end of the room where you can choose options of what you want to do OR you can talk to a person if he/she is jumping to answer the trade/battle/whatever invite.
