Well i don't have a wireless network at my house, so i use my macbook pro to create an adhoc network. This worked great for a year, until I upgraded to snow leopard. My ipod can connect to the WiFi network, but i suspect snow leopard is forcing the airport chip to broadcast an N network, which the iPod can't connect to. Is there anyway to fix this, or is there any other reasons this may have stopped working? EDIT: After checking the apple forums, it appears that some other users have this problem, some suspect a problem with DHCP, but there is no confirmed source of the problem.
