Nintendo Switch System Update 18.0.1 Fixes Wi-Fi Issue And, Yes, Makes General Stability Improvements [IGN]

Nintendo Switch update version 18.0.1 fixes a Wi-Fi bug where networks with certain security settings were not able to be detected. The patch notes, below, provide a guide for those unable to update to version 18.0.1 because of this issue. And finally, in time-honored fashion, the Switch update makes “general system stability improvements to enhance the user’s experience.”

Twitter user @OatmealDome, who digs into each Nintendo Switch update as it’s released, said this latest patch makes no changes to the console’s bad words lists. Nintendo often updates this list without detailing what it’s doing in the patch notes.

With the Switch now over seven years old and its successor reportedly due out in March 2025, it seems likely that small-scale updates are all that’s left for Nintendo’s aging console. But there are still a number of eye-catching Switch games announced as coming out, including Luigi’s Mansion 2 HD, Professor Layton and the New World of Steam, and Pokemon Legends: Z-A. And let’s not forget that, officially at least, Nintendo has Metroid Prime 4 down as a Switch game.

Nintendo Switch update 18.0.1 patch notes:

• Fixed an issue where some wireless access points cannot be found when setting up a new wireless network.
  • If you’re unable to update to Version 18.0.1 because of the issue, temporarily change the security settings for your wireless network to use only “WPA2 (AES)” so you can connect wirelessly to download and install the system update.
  • After updating to Version 18.0.1, restore your network’s security settings to its previous settings.
• General system stability improvements to enhance the user’s experience.
