Local Network on Switch not working since upgrade

I have recently upgraded my internet (xfi) Everything is running wonderfully, but today for the first time we tried to connect our switches through local play and they can't communicate. We were trying to transfer save data and it never loaded. (error message 2216-5000 "unable to communicate with the other console")

Then we tried to connect through Animal Crossing (local) as it's the only game we have multiple copies of. It will come up with the name of the the other person's island but then we can't travel there, it just says "a communication error has occurred"

I contacted Nintendo they sent me to Comcast. Comcast didn't seem to understand my question at all and kept checking my WiFi signal and told me it was fine and the problem was my switch. However I find it very unlikely that all 3 of my consoles suddenly broke after upgrading my internet.

We have tried:

Powercycling all the equipment (both switches, modem) multiple times
Deleting internet settings on the switch and clearing the cache
Connecting every which way between three different switches
Checking the connection in the xfi app, pausing and unpausing the devices
Changing my Firewall settings to low on my modem
Crying and/or screaming in frustration

None of these have netted any results for me. Please send help.

edit: I ran a connection test and the NAT type on both was B, download/upload speeds 32mbps/20mbps

My son and granddaughters systems have faced the same issues. When completely unplugging the modem, or when outside the house, they can connect. But as soon as I hooked back up the modem, they stopped working again.
This is also distinctly a local connection issue, wifi works fine for both of them.

were you able to figure out a fix?

I had the same issue. I would consider myself tech savvy and couldn't find a solution. I did find that when I completely unplugged the modem (not plugging it back in) and restarted the systems, it was able to connect. I believe it has something to do with the new modem security preventing local communications from working in the area. Please let me know if you find a solution.

P.S. I did play with a dedicated proxy server to try to find a solution, I had no luck.

I too am having this issue, but at my Mother's house, everything worked great!

I am currently using a workaround where my PC has ports forwarded specifically for NSO, and I'm using the WiFi adapter to transmit a SSID that has Nat Type A. I don't like this option, so I would like for it to work at my apartment just fine. Especially since I'm paying for faster service than she is. lol

I have gone through everything that I could, tbh.

• I split the 2g and 5g bands to see if that would help, while trying different combinations of connecting to the router on both devices.

• I went through and looked to see if my gateway settings were any different than my mother's, and they weren't.

• I reset everything that is in connection with the work multiple times (even factory reset the gateway), and I still wear unable to create a connection between both devices.

• I spent HOURS researching to see what any issues could be, and every instance was, "I just can't do it after having this gateway device."

• I even tried connecting one of and both devices to a mobile hotspot I have provided from my college, and it worked one time when one device was there and the other was on the gateway, but it never worked again after that.

• I am actually about to buy a router just to bridge the gateway and have ports open for my switches to be "open" NAT for online gaming, because I was having issues with connectivity a before having local connection issues. (I really don't want to spend over $100 just to have open ports on both of my switch consoles)

I am actually quite tech savvy, and have worked in IT in the past, and we all know that IT is just googling things you don't know how to fix lol

I think I'm just finally done and frustrated.

Thank you for that information and for trying different troubleshooting options. Is this the only device you are having issues with?

Thank you so much for those details! Are you currently using a router at all or just the standalone gateway?
