i've been screwing around with this for about 6 hours and i give up. i've got a wired router and a wireless card. i set up an ad hoc network. ipod connects(as observed by the bars in the upper left), but drops out the second i hit the home button. i check the settings for the network on the ipod and discover the ip is 169.254.XXX.XXX, router and dns is blank. i have found that if i set the wireless card as a static ip to 192.168.0.1 then once my ipod connects it will display normal ip address/router/dns information but will still drop out once i hit the home key i have also found out that if i edit the com.apple.wifi file as described in this post (http://www.ifans.com/forums/showthread.php?t=52437&highlight=com.apple.wifi) then the bars in the upper left will stay, but whenever i try to use the internet it fails so i have normal looking ip address etc, i have strong signal strength as observed in the upper left, my computer reports that everything is connected but it doesn't work. $10 paypal to the first person that can help me fix this. i can pay you in approximately one week(probably less). if you happen to play online poker i can pay you through fulltiltpoker or pokerstars instead.
