Hi. 
I have my 3DS right here so I will tell you step by step what I doing, cause I can't figure what's wrong:
1) I open my 3DS (it's in sleep mode).
2) I check that the wireless is enabled.
3) Indeed, the yellow led on the side of the system is on and flashing.
4) On the 3D screen, in the upper left corner, it says "internet" and I have full bars.
5) I take out my stylus.
6) I enlarge my stylus.
7) I click on "Friend List".
8) I click on "Register Friend".
9) I click on "internet".
10) The system tells me: "you cannot use internet registration because you are not online".
11) Why?????????????????????????
