Is Supercell not working? Tsk.

No, I'm not doing anything weird like putting the router's antenna between walls or anything, I'm playing in the living room with full Wi-Fi bars. But I keep getting red Wi-Fi during the game. It's not just for a moment, it's constant - constantly showing up, so I can't even leave and re-enter. I tried again and this time I couldn't play because I was marked as AFK. I'm going crazy.
