Did you try following your quote?omgpwn666 said:I have a question. Why can't I connect to the internet? All wireless devices in my house work except the 3DS. It says that it's connecting and shows a blue signal shooting at the router for like 15 seconds then creates a red X. I tried every channel on the internet (1-11) and turned off the router Firewall. Still no luck. I also tried something I saw on Nintendo forums. Someone help me out, please.QUOTE said:Okay so I called Nintendo today and after xome troubleshooting they figured out it was my DNS settings. I don't know why this needed to be changed, but she told me to go into DNS settings (press the Right arrow when you're in the connection settings to get to the DNS and other settings). She had me erase all the zeros there and put in 8.8.8.8 in Primary and 8.8.4.4 in Secondary, and it connected immediately after with no problems. So maybe give that a try guys. Hope that helps!
How many IP addresses does your router have in its pool, and how many are being used?
