So i have a wired in ethernet connection and wanted to put out wifi for my ipod touch. I went into system preferences, clicked sharing, went to the right and clicked the internet preference, for "share my connection from" i chose built-in ethernet, then in the "to computers using" i chose airport. Then I went to airport and created a network, turned internet sharing on and the network showed up on my ipod touch 2g. I chose the network on my ipod but it said, "unable to join network". I am running 10.4.11 on my computer and my ipod is a 2g on 4.0.
