Gaming "A Communication Error As Occurred" Splatoon 1 fix?

[Overwrite_Pixel]

This is starting to tick me off. Just upgraded my internet and now Splatoon keeps kicking me from battles with either that communication error or "the connection has been lost" error. Out of ten battles, I'd said it'd happen about 5-6 times. Any fixes?

Internet specs just in case anyone needs them
Internet Provider: Xfinity
Ping: 18ms (I don't remember what it was before upgrade)
Download: 21.54mbps
(before upgrade: 500-600kbps, 1mb if im lucky)
Upload: 11.67mbps
(Before upgrade: 200-300kbps, 400 if I'm lucky)

Try wired connection?

Oof, that happened to me when the 2.0 update came out, and I couldn't finish any match whatsoever until last summer where we changed our router.
Try to get a wired connection, but that might not solve anything, sorry for your "loss"

It's been happening to me too in the past few days, when before it was perfectly fine. Maybe it's something on Nintendo's end?

Google Double NAT, if you got a new modem it may have added a 2nd routing layer to your network.

make sure UPnP is enabled on your router (not sure what ports Splatoon uses but you can manually forward them if UPnP is disabled)

Check interference, there's apps you can download on your phone to see what Wifi channel your router should be set to. search something like wireless review or wifi settings in appstore/playstore
