I've been really wanting to play online with my Nintendo DSL ever since it was given to me. Up until now, I've never really had the attitude to actually change my network settings so I can play. The problem is, I'm not the only one that uses our WiFi connection. I found an option in my router that allows a "Guest Access Network." I want to know if I can use this to connect to Nintendo WFC. I have tried it, using WEP security. I enter the correct WEP DS. It recognizes the access point, but when it attempts to connect, it comes up with error 51300 which says it is unable to connect. I then tried to use it without any security. The DS detected the network with a blue unlocked icon. It attempts to connect, but comes up with error 51300 again. So my question is this: Can I use this Guest WiFi as a way to play online? Why does it say unable to connect even though it displays full wireless bars and a blue unlocked icon?
