Alright so I've spent the last couple hours reading pages and pages of troubleshooting etc etc and I haven't found anything, so here I am.
3DS used to connect to our last router just fine, I can't remember the details of it but we got a new router (same brand) and apparently now junk just hit the fan.
No other device has a problem recognizing the network, so it is definitely broadcasting, and definitely working.
The problem is that 1) Access point search will not recognize the SSID (though it recognizes OTHER SSIDs), and 2) When I try to enter the SSID manually I get "The data entered is incorrect." (I've done it 4 or 5 times, so it's not typed incorrectly)
I The router is running on 802.11 Mode : Mixed 802.11n, 802.11g and 802.11b , AUTO (WPA or WPA-2)PSK.
Any help would be really appreciated, thanks ahead of time!
