By using Nintendo Wi-Fi Connection.
you need a Nintendo wi-fi usb connecter witch has a wireless signal. Or you can search for an access point then click on whichever connection such as 2WIRE
Well you can access facebook using the internet channel.
You can get it only at official Nintendo events. Or using an AR and cheat codes.
If you're trying to connect using the WiFi USB stick, you need to turn off your firewall. It's stopping your connection. (For more help I suggest going to Nintendo.com)
To get a web key for your Nintendo DS Lite, you need to access the Nintendo Wi-Fi Connection settings on the device. Go to the "Nintendo Wi-Fi Connection Settings," select an available connection, and then choose "Change Security Settings." Here, you can view or enter the WEP key (if using WEP security) or the WPA key (for WPA/WPA2 security) as needed. If you don't have the key, you may need to check your router's settings or consult your internet service provider.
They are only given out at Nintendo events.
This code means that it couldn't access the Wi-Fi access point. Make sure you are close enough to your router, and your connection settings match. Also, try using WEP (instead of WPA) if you aren't already.
If you cannot log into Club Nintendo on your Wii then you may not be connected to the internet. Check that connection and be sure you are using the correct username and password.
Answer: The Nintendo DS has an 802.11b wireless adapter built in allowing the DS to access the service via any compatible wireless network. Public hotspots that use a captive portal can be accessed after login using the Nintendo DS Browser. The connection settings allows players to configure access to and save settings for up to three different networks. Connection settings can be detected automatically or entered manually. The Nintendo DS is compatible with WEP encryption. Nintendo DSi, released in Japan on November 1, 2008, and in the USA on April 5, 2009, is compatible with both WPA and WEP encryptions.
As much as I despise saying this, there is no possible way of catching or obtaining shaymin anymore. The only way to get it was to go to specific Nintendo events or by downloading it using the Nintendo wi-fi connection last year in November. The only way to get shaymin in Soul Silver is by using action replay codes or by transferring one from Pokemon Diamond, Pearl or Platinum.
Simply go to wii options and configure your internet settings into the Wii. Once you do that you can play any game that has the Nintendo wifi connection label on it with others online. Also you can access the internet using the internet channel which can be downloaded using the wii shop channel.
