So.. when i bought smash bros ultimate for the switch i wanted to play online with my friends, so i paid for online and start the game up. Boom, failure. Nat type is C and cannot communicate with anyone on my switch. I'm currently using a wired connection since i heard that would help, yet it didn't help one bit, the nat type is still at C. I'm hoping that someone is able to either find an easy solution to this problem of mine. Or go through with me into a hell I've been in for about 1 and a half month now.
Smash Online isn’t really great, but you should be able to get a decent connection with LAN. How many bars do you usually get on your Wi-Fi across all of your devices?
Reading: Too much Watching: Not enough Playing: SMTV
When it comes to wifi i get 3 bars, though it sometimes switches between 2 and 3. Though that is not the problem here. The problem is that my nat type is stuck at C at all times. I’ve tried using wired connection, but to no avail. @GyroZeppeli
@SwitchForce Nothing to do with either game or hardware. There is a thing in your network called Nat type, and these Nat types can have different attributes. My Nat type is C, so that means i can't communicate with any other consoles around the world. The nat types i'm aiming for are either A or B. If i had these nat types i could connect to anyone, making me able to play online. People had been saying to me that a wired connection would help, yet that didn't happen. The wired connection didn't have any effect on the Nat type. So it really has nothing to do with the game at all.
I had the same problem about two years ago and tried a lot of things and nothing worked.
I then learned that my provider had disabled a setting which stoped me from getting more than nat type C.
Luckily I could just ask them to change it and ever since I have nat type A.
I forgot the name of the setting but you should check with your provider if it prevents you from getting a better nat type.
@Incure Have you already tried Port Forwarding? If the router won't let you set a port range, DMZ would be an option if you restrict it to the Switch's MAC. I've got mine on DMZ and don't have any issues.
@Incure The NAT type can be because of configuration of your router, double NATting, or backend configuration by your ISP. Did it work at one point and suddenly stop, or did it never get a NAT type above C?
If never, it may still be router configuration on your local device. But it's hard to troubleshoot that without actually being able to see the settings. You can set a DMZ for your Switch's IP, which only works if that's the only device on the network you need in the DMZ. For testing purposes that can at least help diagnose.
If it's not that, though your ISP could be implementing what is called "carrier grade NAT" and is often used by cellular data providers, but sometimes wired providers as well in dense areas. Are you using a wired or wireless provider? If that's he case, there's nothing you can do, they're basically scrambling dozens of customer IPs behind a single IP to have more people sharing a smaller pool of IPs they own. It works fine for almost everything except P2P connections like gaming and VOIP. In those cases you'd need a VPN service, and a VPN capable router or a PC from which to share your connection to get through it.
@JackEatsSparrows I've tried port forwarding, even with nintendo's own guidance, but nothing has worked. I've figured out that the problem i'm having may have something to do with the router. Let me explain. I am not an adult, and i live with my mom. We live in denmark and we have a network thingy called "Smart wifi" which basically is small hotspots that has been installed around my house that send wi-fi out to our wireless devices. Though as the "hardcore gamer" (ew) that i am, i use a stationary pc so i wanted a cable connection, the smart wifi does not allow that. SO. we decided to use a router as a switch, so that I was able to use a wired connection with my pc. so our so called "Switch" is not a real switch. SO, i've talked to one of my family members who works for our internet provider for some information. AND HE TOLD ME, that i could try to use a "real" switch instead of a router, because the router may be blocking for some connections that i don't know about. So i'm going to try and do that, and i will make an update once i've done so.
@NEStalgia Dude, i think my brain-juice just depleted, you clearly have like an above average IQ. I do not know whether or not my internet provider prioritizes wired connection or cellular since i have access to both. My nat type on my Nintendo switch whilst using both wi-fi AND wired connection, would always be C no matter what i do. I've spoken to my internet provider like... 8 times now, and even they don't know what to do. Though if you imagine you have a solution i would love to hear it. I'm just.. not really a genius so you're going to have and explain in a way that i can understand it. Imagine that you're talking to a child or an animal, and try to explain it. I know it sounds stupid, but i am, so bear with me.
@Incure Oh, I get what you're saying! It's sort of like what @NEStalgia was saying in terms of grouped IPs for wireless/cell providers. That's not as big an issue in the States due to how most traditional providers are structured, but it's pretty common with cellular service providers here. I can see how a router could be sticking its fingers in the pie in that case, and an actual switch could be better. For sure, keep us updated. Like I said, it's not as prevalent stateside, but it could turn out to be a good solution for anyone else experiencing the situation.

@Incure Haha, no problem. I've just been through so many weird network/gaming issue over the years I've probably seen it all by now.
What you described seems promising though. If you're connecting to a router that's inside that could definitely be the issue. Is this router connected to the Smart WiFi wirelessly (a.k.a. configured as a wireless bridge), or is it plugged into another router elsewhere along with the Smart WiF system?
Have you connected the Switch directly via the "smart WiFi" in wireless mode to see if that works? (if the Smart WiFi is outside the second router?) I presume the Smart WiFi is a "mesh system" that plugs into the ISPs router (unless you get your internet entirely over wireless via public WiFi or some such....I know various locales in Europe have those kinds of services....here in the States, outside Seattle/Portland/NorCal, such creatures are imaginary things from the future. )
I'm picturing that your second router has created a double NAT so the outside world (other Switches) can't find your Switch through the two hops. But if it still doesn't work if connecting wirelessly right to the "smart" mesh, that probably debunks that theory.
For now it's best to eliminate the extra hops, just to troubleshoot "at the wall." So try connecting (wirelessly) your Switch to the farthest up-stream node. Where the wire comes in from the ISP to "their" router (or if there is a router that marks the cell connection if it's a cellular ISP), try connecting directly to that. If it doesn't work there, then the problem is either that device or the ISP itself. If it's that device, that's where the port forwarding and such should come from (and you can either get a "real" switch for the inside point, or reconfigure the router to not actually route things - any router should be configurable as a dumb switch.) BUT....if it's the ISP.....things get more complicated if they can't identify resolve it internally. Let's work on the indoor possibilities before looking at working around ISP limitations.
@NEStalgia I'm actually surprised you guys understand, this is great. Okay, to answer your questions..
the "smart wi-fi" i mentioned earlier is connected directly into the router that now functions as a switch. The router that functions as a switch does NOT send out wi-fi, it's only the smart wi-fi we actually get wi-fi from. but i'll definitely keep you guys updated once i figure this out.
@Incure Ahh, ok, so what is that router/switch plugged into? And is it plugged in via the "WAN" or "Internet" port, or the numbered 1, 2, 3, 4, 5, ports?
@NEStalgia The box that sits on our wall which basically grants us internet, has a cable from it's first port. Dunno if it's specifically called port 1 but that's what i think. that cable goes into our switch/router in a port that's called "LAN 1". then my switch is connected to the second port, pc in the third, and the smart wi-fi is in the 4'th i believe. i don't recall anything about WAN though.

From your wall it should go into the "WAN port" (the blue one) otherwise port mapping won't work in your router. Start with that and see if it works.
