>According to Nintendo's Error Code search, the 022-2634 error code means that the "3DS is unable to connect to an Access Point"
Error code 022-2634, as said above, mean that you are not connected to the Internet because the 3DS cannot find an access point. If you are near your Internet source and you still can't update, make sure that your 3DS' s wireless switch is on.
Hope I helped!
