WPA is what you were trying to say.it depends what internet aswell cus ds lites only connect to routers with WEP keys whereas DSi's connect with wep and tpisk (or whatever it is)
Although, if you have your own router, it shouldn't be that hard to change the settings no? [:
DSL >>> DSi
Sorry if I'm being blatantly stupid here, but I just don't know... Does the DSiXL exist? 9___9' I don't keep up with all the electronic news but I remember hearing about it somewhere...
