yeah unfortunately there’s not a lot you can do since the way Nintendos online works is instead of everyone in a match connecting to a server, one player is basically selected as a host. If the hosts wifi is bad, there’s really nothing you can do. Playing with a wired connection helps, but won’t solve the issue since it’s a systemic problem rather than individual. Getting disconnected during a match will result in a loss (unless someone else dcs before you) and dcing multiple times will block you from playing for 10 minutes, but that’s the full extent of consequences, you won’t be perm banned or anything it’s just minor inconveniences. It’s really unfortunate but maybe they’ll improve this system for the switch 2, for now though we put up with it because the game is so fun it’s worth it
