Depends how much you want to play online. I've changed mine to WEP or none and then back to WPA after I'm done playing a couple times.
Thank goodness the Wii and 3DS (and I think DSI and XL) supported it.It's real unfortunate that WPA support wasn't in DS.Can't really blame them though considering the DS came out in 2004 though. WEP was still barely a thing back then.
