Apperently when the nintendo ds was made and using wifi for online play, it was limited to only support for WEP security, but we live in 2016, not 2006 like 10 years ago. We have routersw with AES and other better encryption passwords, I myself have a AC1750 dual band router and i wouldn't even know if it supports the other one needed for NDS wifi but it is not recommended by any means. Only other option is a usb wifi connection thing by buffalo, which isn't even made or sold anymore. So i was just curious, is there any way to get around this without Unguarding my security? If not, is fine, I accept it.
