No longer can connect my Switch to internet, 2110-2101 or 2110-2003 errors

[Ondrashek06]

Out of nowhere, my switch just refuses to connect to wifi with either of these errors appearing whenever I try (on SysMMC).

Have you tried to google? Because I found a whole thread about it on Reddit where people seem to have solved it as well.

Yes, have tried power cycling it 3 times. Doesn't work.

Well then, try to change channels on your network and see if that helps, or reboot the router/ap if you haven't in a while

Every other device can connect to the network. I think that it's a problem with the switch, not the network...

You would be surprised how often a restart of the network can help

Do what @linuxares suggested, restart your network.

I would also try forgetting the network and setting it up again.

Restarted the router. Still the exact same issue.

Try to delete your wifi profile and add it again and see if that helps.

Also done. Issue still persists.

Yes, didn't help.

Do your emunand work?

Tried it, also doesn't... Even though it worked before I swapped to SysMMC.

What happens if you try like your phone as a Hotspot and try to connect via it?

 

[urherenow]

assuming you have a dock, how about docked and connected with ethernet?

It has problems only with the main network, the 5GHz one connects just fine. But 5GHz networks tend to be unstable, I absolutely do not want to disconnect during a salmon run shift.

I used to have issues with my connection due to incompatible wireless network security type, but I'm not sure if it's the same issue you're experiencing. Which one do you use? Switch supports WEP, WPA-PSK(AES), and WPA2-PSK(AES), so either one of these should work.

WPA2-PSK(AES).

I'd try going into the maintenance mode in order to clean the cache, seeing that you've already done everything else that I would personally do.
Here's how:

1. Turn off your console.
2. Boot into RCM the way you usually do and, before sending your fusee.bin payload, hold volume + and volume - at the same time and let your console boot into CFW. You'll see an Atmosphere logo, followed by a Switch logo. After a while your Switch will enter into the maintenance mode. At this point any pending update and cache is deleted/cleared (on your sysNAND/emuNAND).
3. Press the power button once again and It'll shut down the console.
4. Boot into CFW the way you usually do and see if that fixed your connection issues. Don't forget that connecting to the Internet is safe only if you have DNS MITM in place.

Hope that helps. Other than that, unfortunately, I have no clue what could be an issue.
