Nintendo Switch 2, disconnects continuously

This is becoming really infuriating and making me disinterested in the game. My internet connection is good and it's the only device on my 2.4GHz network. My game disconnects every 3 of 4 games. Usually when processing the result (possibly more so when my opponent forfeits) but sometimes mid game also. It happened 4 times during ultimate gauntlet including after I won the final so I didn't get the rewards I deserve. It has happened in 3 games out of 12 in champions league this weekend, all were won or ahead by multiple goals, making my record terrible. Please fix this issue, it is not my connection issue!
