How to connect your Nintendo DSi to your wireless network

To fully take advantage of Dragonquest IX’s online features, we had to connect each boy’s DSi to our wireless network, which turned out to be a little tricky.

First a little info about wireless protocols:

WPA is the newest, strongest, and most widely accepted protocol for wireless connections.  Everything between the wireless piece and the computer (wireless access point) is encrypted using WPA.  There are 3 – 4 different types of WPA (pro, home, etc.), but most importantly, WPA hasn’t been hacked yet.

WEP is the original encryption protocol.  It’s much weaker and has been cracked, so it’s not used as often.   You wouldn’t want your household network/laptop using WEP, as it’s been hacked, and your data could be intercepted and maliciously used.

The Nintendo DSi used only WEP.  Most computers and routers can be set up for WPA or WEP, but you must choose only 1, because a single router can’t use both at the same time.

The way we solved this problem was we installed a separate router that supported WEP, and turned it into an access point, by disabling all of its router functions.  This enabled us to use WEP to connect the DSi’s to an access point, so they’re on the network and have Internet access.  All without endangering the security of the other computers in our house, which still wirelessly connect using WPA on our original router.
