My 32Gb iPod Touch refuses to connect to the internet from my (snow) Airport Extreme. The iPod gets a DHCP address from the router and I can ping the iPod from my MacBook Pro. But iPod Touch internet applications (Safari, Mail, etc.) report that they can't connect. My Airport Extreme network is WPA with MAC address filtering. I've added the iPod Touch's IP address and the Airport Utility application reports that the APX can see it. I tried disabling MAC address filtering, changing to WEP - even disabling any form of Wi-Fi security whatsoever - but I still can't get it to work. I went to a friend's house yesterday and got on his Wi-Fi network straight away, so the problem's not with the unit. I've reset the Touch's network settings, done the "Forget This Network" trick, etc. etc. etc. Anyone out there using an old-style Airport Extreme (the one shaped like a UFO) who has got their iPod Touch working with Wi-Fi?
