Well, I got an R4 a week ago, and even though the R4 FAQ sticked in the board says that Wi-Fi does indeed work, I am having troubles using Wi-Fi with my JAP Pokémon Platinum game. Any suggestions?
R4 is absolutely capatable to Wifi and all the wifi setting are saved in the firmware of your DS. So it is impossible that R4 made your wifi not working. My suggestion is...... check the settings on your ds or on the wireless router.
