Usually, when I try to use my Switch for online connectivity the system is connected but I keep getting error messages and won’t actually connect to the online servers I try to access.
I live in the countryside with my family, so maybe that’s why my Internet is so wonky?
But I’m still able to access the online classic games for the NES, SNES, and Game Boy at least: I just can’t play the regular Switch games.
Any advice for a better connection?
Whelp, it’s not great. Ideally, you’ll need at least NAT type B to be able to play online without issues.
You may improve the score by assigning a static ip address to your nintendo switch in your router settings, then add it to the router’s DMZ. But this is assuming the source of the problem is the router’s firewall. If the source of the issue is your ISP using CGNAT, then not much you can do beyond changing ISP or talk to your ISP to see if they have any online gaming-friendly internet plans.
Could tunnel to a VPS using a VPN. VPN deals with the CGNAT traversal, and VPS gives your home network a static public IP. But would need to do it at a network level cause I doubt a switch can do that directly
