Today I tried connecting my DSi XL to the internet. It didn't work. This is really awkward as I can remember going on Wi-Fi easily just like a month ago. I tried clearing the settings, and letting the DS put automatic settings. Nope, still doesn't work. I take the error code that it gives, and put it on Nintendo's website. The site explains that "the settings configured on your DS does not match the security settings of the router". I followed Nintendo's guide which taught me how to manually assign an IP, how to configure the DNS, and the Subnet mask and the gateway and all, and I followed all of the steps correctly. The connection test failed again. I am 100% sure that my router has no security settings on whatsoever. So I can't fathom why it didn't work. Last month though, I did have security settings. A whitelist to be exact, and I followed the same Nintendo guide, and it worked. But now, with no security at all.. it doesn't work? How does that in any way make sense? That's so retarded. So yeah I really need help here. Thanks.
