Nintendo has been steadily refining both the Switch and Switch 2 platforms this month. After dropping a major update earlier in November, the company has now followed it up with a lighter patch. While this new firmware isn’t loaded with flashy features, it fixes a few problems that were bothering players, especially those getting ready to move their data to the new hardware.
A Follow-Up Patch After a Big Monthly Update
This update arrives just weeks after Version 21.0.0, a sizeable release that brought changes to the HOME Menu, GameChat upgrades, game card improvements, and updates for the new Switch 2 controllers. With big updates usually come unexpected issues, and Nintendo is clearly cleaning up the edges with this smaller patch.
Fixing Transfer Errors Between Switch and Switch 2
Repeated Error Codes Finally Resolved
One of the main problems players reported this month involved system transfers. When trying to move data from a Switch to a Switch 2 using local communication, some users repeatedly ran into two specific error codes:
2011-0301 and 2168-0002.
These errors interrupted the transfer process, forcing players to retry the move over and over. Nintendo has now fixed this issue, making the transfer smoother and far more reliable, an important improvement for anyone upgrading to the new console.
Wireless Connection Issues Get Patched
Controllers and Bluetooth Devices Failing to Reconnect
Another frustrating bug involved wireless connections. A handful of users noticed that after waking the system from Sleep Mode or after turning off Airplane Mode, their wireless controllers or Bluetooth audio devices refused to reconnect.
Since wireless accessories are such a big part of the Switch experience, this was more than a minor annoyance. With Version 21.0.1, controllers and Bluetooth audio should reconnect normally again without players having to restart their system.
General Stability Improvements Across Both Consoles
Aiming for a Smoother Overall Experience
Nintendo included the usual “general stability improvements” in this update as well. While the company rarely explains what these tweaks are, they generally make the system feel more responsive, more reliable, and less prone to background crashes.
These small adjustments add up over time, and many players notice smoother menus and fewer random issues after updates like this one.
Full Breakdown of Version 21.0.1
Switch 2 – Update Version 21.0.1
- Fixes repeated 2011-0301 and 2168-0002 errors during system transfers.
- Resolves controller and Bluetooth audio reconnection problems.
- Includes general stability improvements.
Nintendo Switch – Update Version 21.0.1
- Fixes the same recurring error codes during transfers to Switch 2.
- Adds general stability improvements.
Why This Patch Matters
Even though the update is small, it addresses real problems players were running into, especially early adopters preparing to move to the Switch 2. Smooth data transfers and reliable controller reconnections are the kind of behind-the-scenes improvements that make new hardware feel polished from day one.
Nintendo has a long history of pushing smaller fixes after major updates. This pattern suggests the company is paying close attention to user feedback and working quickly to resolve anything affecting day-to-day gameplay.
Looking Ahead
Nintendo may share more details if they uncover additional issues or if they release another follow-up patch. For now, Version 21.0.1 appears stable, and players should already notice fewer interruptions and smoother system behavior.
If you’ve installed the update, you might have already seen the improvements, especially if you were running into the transfer errors or wireless connection problems earlier.
Have you downloaded Version 21.0.1 on your Switch or Switch 2 yet? This patch should make your console feel a bit more reliable and ready for the months ahead.
