My laptop can connect to the internet but my 3ds can't like it used to. I'm getting the error 003-2103 whenever I access miiverse and other stuff related to the internet; Except for the internet browser. I can use the browser perfectly; The problems are in the online service of games in other apps . The blue icon with the internet sign always become gray and enabled. When I test the connection, the 3ds to the router works fine but the part when the router connects to the internet fails. What can I do with this issue?
