I bought a new Nintendo wifi connector and it doesn't work. I keep getting error code 52003 when I try to connect my DS and 52040 on my Wii.
I know its not my internet provider because my friend has the same provider and his works.

I've tried:Uninstalling the software and reinstalling
Disabling all of my security programmes
getting a new wifi connector
disconntecting my wireless phones.

I am so annoyed and would really be happy if somebody helped me.
