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? 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.
