Ensure your device's Wireless Communication is turned on as udsploit (used in the next page) will need the wireless module to be active to function, and some devices (New 3DS and 2DS) cannot adjust the Wireless Communication setting from the Homebrew Launcher. Wireless Communication only has to be on; connecting it to an access point is not required.
Note that Cart Updates will only deliver updates to core features, such as the System Settings, Home Menu, etc. Cart Updates will not deliver updates to Nintendo 3DS Sound and Network features, such as System Transfer, Internet Browser, StreetPass Mii Plaza or eShop.
