Hey guys, so I've been getting this error code at my apartment on both my Wii U and 3DS ever since day one of Mario Kart 8's release. On rare occasions I'm able to connect but the times that it lets me do it are few and far between. I don't have this issue on my 360 or PS3 either, it's just for the Wii U and 3DS. Here's what I gathered from the Big N's site: This error code typically indicates an issue communicating and matchmaking with other players. This is often caused by network firewalls blocking necessary network traffic. This can be caused by your network, or the network of the person you are connecting with. If these steps do not resolve your connection issue, have your friend try them as well. Here's my information... I live in an apartment with wifi that is paid for and provided by my landlord. I have my own personal router (shh, I don't think I'm supposed to) so that I don't have to deal with connecting with everyone else in the apartment, though we still all share the same connection. Last year a Nintendo employee helped troubleshoot these issues using a remote desktop and messing with my router settings. It's also a Netgear router, so I don't login using my IP address, I use routerlogin.net. However he was unsuccessful even after opening ports and stuff like that. I'm wondering if you guys know of anything that I can do to get this settled. I can obviously mess with my router's settings to my hearts content but I obviously can't mess with the landlord's router/modem. Are there any steps that you suggest or things that I can do to help make me connect more often, because once I do connect I actually stay connected. It's just that initial connection that's a bitch. If DNS has anything to do with it, I would like to stay on the Tubehax DNS. If you need any more information I'll be happy to tell. Thank you!
