friend codes are basically what people with ps3 online or xbox live is...their xbox live name...thats basically what a friend code...you make a list of all your friends and play them in all sorts of games...

and i think the easiest way for you to get your ds wifi working is to get close to a router or something with internet and test the connection....it should detect the internet connection and where its coming from..it should be strong...and the ds should automatically set up the basics (what youre getting the signal from) you do everything else...though i dont mess with it..as long i get a connection..thats fine with me..

after that it should work..
