BTW, I have to correct my earlier claim that the DSi doesn't do WPA, it has a second connection setup menu ("advanced settings") that can cope with WPA just fine, I was using a WPA2-TPIK WLAN recently. Trying to add the connection gave me a "you have to use advanced settings for this" message, the advanced settings had a second list of connections numbered 4-6 (I assume 1-3 are for compatibility with DS software, haven't taken my DS games online before but I heard they use statically linked WLAN libraries so they can't access the DSi's WPA capability) and accepted the connection just fine, I used the browser and DSi Shop on it.
