Yeah, that’s what I found when googling. Checked, and my internet connection had NAT F (although weirdly, it worked OK for Mario Kart). When I tried the wifi extender network, for some reason that had NAT B, which is when I managed to play a couple of laggy games.
Any safe tips for improving the NAT thingy when the Ducky ethernet guarantee is unavailable? All of the suggestions I’ve seen just involve opening all the ports on the router, which I’m not particularly keen to do.
