internet connection error codes need some help

[Rob]

i'm at my friends house (he got his wii on release), i don't know how but he didn't know you could use wi-fi to connect his internet. o well. anyway the wii knows his wirelss thing is there and has saved the setting (ie passwords etc), he got an error code, begane with a 52030 will add rest of code when stopped playing redsteal. we actualy put the wii's front and the router's antena about 1mm apart just in case.
anyone know anything would help please.
i'll edit the rest of error code soon.
thanks
ok i found that its something to do with the settings either with the wii or router. i found some helpful sites if anyone else has an error code etc.
http://www.wiierror.com/ - easy to understand site
http://www.nintendo.com/consumer/systems/wii/en_na/errors/index.jsp - the offial one, but quite complicated for people who arn't brainy.
