How do I connect my DSi to my WI-FI connection?

1. Turn on the Nintendo DSi
2. Click on the wrench icon to access "System Settings."
3. Select "Internet" on the third page of System Settings.
4. Select "Connection Settings" and tap the "None" bar in "Connection 1."
5. You have the option of setting up a connection manually, or searching for available connections in the area. You may also access your Nintendo Wi-Fi USB connector, if you have one (the product has been discontinued). The easiest thing to do is select "Search for an Access Point."
6. Your Nintendo DSi will list the names of any wireless access points in range. A gold, unlocked icon next to the connection's name signifies an unlocked WEP (Wired Equivalent Privacy) connection that can be accessed immediately. A locked gold icon signifies an encrypted WEP connection that requires a WEP key (password).
7. If you are accessing a locked/encrypted connection, enter your WEP key. You may also click "Change Security Settings" to enter a WPA (Wi-Fi Protected Access) key.
8. If your WEP key is correct, your Nintendo DSi should connect. You can test your connection to verify.

Here's How:

1. Turn on the Nintendo DSi
2. Click on the wrench icon to access "System Settings."
3. Select "Internet" on the third page of System Settings.
4. Select "Connection Settings" and tap the "None" bar in "Connection 1."
5. You have the option of setting up a connection manually, or searching for available connections in the area. You may also access your Nintendo Wi-Fi USB connector, if you have one (the product has been discontinued). The easiest thing to do is select "Search for an Access Point."

A locked gold icon signifies an encrypted WEP connection that requires a WEP key (password).
7. If you are accessing a locked/encrypted connection, enter your WEP key. You may also click "Change Security Settings" to enter a WPA (Wi-Fi Protected Access) key.
8. If your WEP key is correct, your Nintendo DSi should connect. You can test your connection to verify.
9. You're set! Now you can surf the Internet, purchase games and add-ons in the Nintendo DSi Shop, and play games that allow wireless access and competition (with WEP connections, only).

The reason this is happening is because Starbucks makes you login to an account before you are able to access the internet. Unfortunately the DSi is unable to use this login page as the DSi does not have a web browser. However there is still a way for you to get online.
You will need

• A laptop
• USB Wi-Fi connector for the DS

Then just follow these steps

1. Turn on your laptop and access the Starbucks Wi-Fi
2. Plug the USB Wi-Fi connector into your laptop.
3. You should now be able to easily play your DS online

How to Get WiFi for DS

Depending on which DS you purchase, you can use the console's Wi-Fi settings to play games against other players around the world or download additional content. The Nintendo DS and Nintendo DSi allows for gamers to compete with one another as long as the game being played supports these connections. The DSi features a built-in web browser as well as a store where entire games can be purchased and downloaded. In order to access these features on either console, games must first locate and connect to a wireless access point.
Difficulty:Easy Instructions Things You'll Need

• Nintendo DS or DSi

1. Connecting with a DS or DS Lite
   • 1 Insert a game cartridge into your DS and power it on. Begin the game, and on the main menu, choose the option for setting up a Wi-Fi connection. The location of this option differs in each game, so check your game's manual for where to find this option.
     
   • 2 Choose "Nintendo Wi-Fi Connection Settings" from the setup screen and press "A" to select this option. Choose one of the connection spaces to use for this location. You can save up to three locations at a time.
     
   • 3 Select "Search for an Access Point" and press "A". On the next screen, choose the blue padlock. This is an open connection. Selecting it will connect your DS to this wireless connection.
     
   • 4 Return to the main menu of your game by pressing "B". You can now play games over the Wi-Fi connection.
     
   Connecting with a DSi
   • 1 Power on your DSi and wait until the main menu opens up. Once on the main menu, scroll until you see the "Settings" tab, which is illustrated by a wrench. Tap on it to open the menu.
     
   • 2 Click the right arrow until you reach the third page of the System Settings menu. On this page, select the last option, which is labeled as "Internet". Select "Connection Settings" from the next menu. This item will have an image of the DSi to the right of the option.
     
   • 3 Choose one of the connection boxes to set up a new Wi-Fi connection. These will have the word "None" listed. You can have up to three saved connections on the DSi at any given time.
     
   • 4 Tap the top box on the Connection page. This will automatically search out a wireless access point for you to use on your DSi. Choose an access point with an unlocked icon; these connections do not require an administrator password to access.
     
   • 5 The DSi will test the connection, after which you'll be able to play games online, download new content or browse the Internet.
     

Tips & Warnings

• Not all DS games can be played online. Check the back of the game's box to see if it supports a Nintendo Wi-Fi connection
  
• The Nintendo DS cannot connect to secure networks. The DSi requires a password from the administrator to connect to these networks.

To connect your Nintendo DSi to the Internet, your system will need to be in a Wi-Fi capable hotspot. If you have broadband at home, you'll need to set up a wireless router with a network name and a password. If the public hotspot requires users to enter login information via a webpage, this generally means that it will not work for DSi online play.

In the Settings menu, you'll need to select one of the first three profiles and search for your compatible Wi-Fi hotspot. Once selected, you'll need to enter the password of that hotspot. After a short test to see if the connection will work, as long as the information you've provided is correct your system will connect online. If you receive an error code, please note the digits and check Nintendo's Wi-Fi technical support website at www.nintendowifi.com.

It's rather simple, you turn on your gaming console (DSi in this case,)then look for setting and goto wi-fi connectivity, turn it on and go out into the main menu, go into wi-fi sort of "app" thing and enjoy but remember a DSi will only be good for looking up texts or something like that not rather good at playing games, why not just buy a laptop/desktop computer?
