Be sure that your Internet connection is running smoothly and the green lights are all up. If you have a Nintendo Wi-Fi connector, you need to have the software installed and your computer connected to the Internet.

Same as above :P

The unit can connect to the Internet by utilizing its 802.11b/g Wi-Fi, which is built in, for wireless connections or via a USB-to-Ethernet adaptor for DSL connections.
For your wireless connection or Wi-Fi, the 802.11b Wi-Fi has a data rate of 11 Mbits per second and has an indoor range of 30m or approximately 98 ft. The 802.11g has the same indoor range, however the data rate is at 54 Mbits per second. If you have an existing wireless connection or are in a Wi-Fi hotspot, the unit will connect to your wireless connection automatically out of the box. If you do not have a wireless network, however, you will need to have your wireless network subscription done or set-up first. Once you have wireless Internet access, you then search for your access point, put in your security settings and you’re good to go. It would also be advisable to have a wireless router for this so that you won’t have to shuttle the connection between your PC and your Wii. Another option would be to connect your Wii via the Nintendo Wi-Fi USB Connector. This accessory allows Nintendo Wii users who do not have an existing Wi-Fi connection or a compatible Wi-Fi network to create one through their broadband or DSL connected computer. This is inserted into your existing computer’s USB port and the Wi-Fi USB Connector acts as a wireless access point for the Wii. This allows the user access to the internet and to play Wi-Fi Connection games from Nintendo Online.
For your DSL connection, however, you will need to have quite a few things. You can use a WII LAN adapter to connect your Wii to your DSL modem. You can also use a router so that you can use your PC and your Wii at the same time. With the LAN Adapter though, to use or plug in the Wii, you must disconnect your PC. This can be quite tedious since you will have to plug in and out your PC and your Wii every time you need to use one or the other. A LAN Adapter is fairly cheap, but if you get a router, your PC and your Wii can go online at the same time, saving you the hassle of connecting one or the other when you need them. You can then hook up the existing ethernet cords to the back of the router and connect it to the Wii via a USB 2.0 cord.

i hope this helps
