If you go to Services (search from start menu) is WLAN AutoConfig started and set to automatic?This is what i get... anyone know why?
No, DNS/IP won't help.
Actually, the 3DS doesn't like to stay connected to Hotspots like it does routers (I have no idea what the difference is...) It often closes out for short moments (which, in Pokemon's case, causes a total disconnect for the game), as well as a quick disconnect whenever you open/close the system/go to Home Menu.
You all really might want to check out the HomePass thread on GBATemp, since they cover all this networking stuff for TONS of different systems/devices to work with 3DS.
Also, SGMarcus, could you add the link to whatever is the newest revision of your InstaCheck to your Signature or something, so it's easier to find? Sorry, it's just really useful, but would be easier to just reference people who comment long past you posted it to it instead of the original.
Hum. I know they said that being unable to reconnect and having to restart the hotspot is normal, but there's got to be some way to fix that, or in my case make it more stable. I can't check people's eggs because of random disconnects :(. I'll try looking on gbatemp.
