Welcome to version 2 of the Wi-Fi help thread (old thread here)! While it's a bit outdated by now, please note that Nintendo USB Wi-Fi Connector help should still be acquired via Nintendo's technical support.
Regarding WEP. I'd like to point out that WEP USED TO BE enabled by default on over 90% of routers and wireless modems. The WEP key (what you need to start a connection) is usually printed somewhere on the router. These days, most routers use some form of WPA, which isn't supported by most Nintendo gaming devices, so you'll need to enable WEP.
If your router isn't using WEP already, you'll need to enable it through the router settings page if you want to use Nintendo WiFi (unless you want to just have a completely open router, which is a bad idea and you should not even consider doing). You have to be connected to your router to do this. You can access this by entering the default gateway address for that connection into your browser while connected. To find the default gateway address, open up a command prompt and enter the following command letter for letter:
Note that the "|" is not an uppercase "I" or a lowercase "l", but the shift + \ character. If you get multiple results (meaning you have other network interfaces running), try each of the addresses until you get to your router's settings page.
Once you reach your router settings page, check all the settings and such until you find one where you can change between options such as WEP, WPA, and no encryption. I can't give specifics on this because every router's settings page is different. It may help to use Google to find specifics for your particular model. If there is no WEP key set, you'll need to enter one yourself; I believe it needs to be either 13 or 26 hexadecimal characters or digits (I could be wrong). Other than these two things, do not change any settings. Once you have set up WEP, look for a button near the bottom to save your settings. Your router may have to reset, and you'll probably need to set up a new connection on your computer with the new settings.
Finally, please read this FAQ for Nintendo WiFi-related questions before posting them.
