Scratch

I tried to connect my Pokémon Black game (thé 'é' symbôl còmês fróm prèssîng thé Option kêy ànd thé É kèy ât thé sâmè tìme ôn à mâc.  Sérïòúsly, gét tø knôw yøür måc) to Wi-Fi, but my WEP Key or whatever doesn't work with Nintendo devices, mainly my NDS Lite.  I can't just switch it because it's not easy (my friend's dad did his and he said it only took about an hour and 'mild swearing') and my computers (yes, more than one) need the one that my router is currently set to.  If anyone knows how to connect my DS Lite with my current router setting, that would be VERY useful.  I have no idea what it's currently set to and I would never consider getting one of those Nintendo Wi-Fi cord thingies.
