A problem has been identified whereby if you are running a Netgear DG834G router with v3.01.38 of the firmware and your computer is connected to the router via a cable, your iPhone/iPod Touch cannot be seen by the computer.

The reason for this is that there is a bug in the firmware. You will either need to downgrade the firmware to version v3.01.25 or upgrade to the latest version.
