About nintendo dsi Browsing

guyz pls help me. i want to surf to the internet in my dsi.we have a wifi connection here in our house. my problem is i dont have a browser in my dsi.i tried to watch video about how to download the website in the dsi shop but when i try to go to dsi shop. a message appear that is different from the video. sorry cant read the message because it was japanese. but for sure when i try to open the dsi shop, im always redirecting to the wireless setup in the setup of the dsi.

It probably wants you to update to the latest firmware. It'll block flashcarts if you have one at all. DSi web browsing is slow anyways. I just use it if I absolutely have to.

Technical help plz
