So ever since I’ve had my Nintendo switch. I have been playing Pokémon Sword and other game but I’m not able to go online. I can’t trade or battle in Pokemon Sword at all at my wifi network. Unfortunately in my case, the NAT Type I have on my switch is D, which is why I’m not able to go online as I need NAT Type A or B to play with other people online.

So I’m asking if anyone has any information or tips on how I can try and fix this because I’m out of options and have no ideas on how to fix this

If you have any help then I would appreciate it if u gave me a solution thx very much.
