OK.. Heres a Simple guide to those "Newbies" who cant connect to GTS or Random Battle
1st: Make sure you have patched you ROM with Rudolph's Child's Play Patch... (Thats what i did)
2nd Make sure that you talked to the girl after you finished the second Gym and the Plasma event... She'll tell you about Wi-Fi and
give you C-Gear..
3rd... Always and ALWAYS Make sure you dont have any event pokes in your party... its not allowed in Wi-Fi
4th: If you caught or have a pokemon from IN GAME, Make sure you change it name @ the name rater in Huin..
For Example: Tsunabeaa change its name to ENGLISH ones BUT its only limit to 5 Letters..
(If your pokemon is from HG SS, you can still go through the wi-fi)
Poke Sav Section
If your going to wifi with a pokesav pokes, there is a chance you might get disconnected... WHY??
Because the wi-fi battles check it first if your poke is legit or not...
In order to get through you must make your poke seems legit..
For example EV trained Tsunabeaa, mmust be equivalent to 508 eg. 252 HP 252 Atk and 4 Spd...
The rest make it legit, where it supposed to be caught and etc etc...
That way you can go through wifi battles with your sav poke...
(Make sure you have Patch v4 )
that should be it by now...
