No a WiFi router is required.
you just need to be near a wireless Internet router. most malls have wireless Internet
A wireless router is a piece of hardware, you can't download one.
The only 'code' you need is the passkey for your wireless router.
YES. With the Nintendo dsi browser the you can get for free from the dsi shop. NOTE: you need wireless internet access to go onto the dsi browser and the dsi shop.
If you mean wifi, you need a router. If you mean Internet browser, you can download one at the dsi shop
Only if your computer has a wired connection instead of wireless. If you are using wireless, the DSi can connect to your router, it has its own wireless capabilities inside it. If you are not using wireless, you can buy a Nintendo USB wi-fi adaptor which plugs into your computer and turns it into a wireless hotspot that the DSi can connect to.
you go to Nintendo dsi shop and click on it + you need to have wireless internet
