Do I need to run the DigiDo home networking software on a computer that is physically connected by wire to my wireless modem gateway?
Yes, when the computer that is physically wired to the wireless gateway is used to set up the home network. The DigiDo software automates the installation of any needed networking drivers and configures the network settings (including wireless security parameters) for the home network. It is optional if you want to run the DigiDo home networking software on secondary computers that are attached to the wireless gateway via physical wire. These computers can simply be plugged in directly and will work without special software. If the DigiDo software is installed it will help show status of the network connection, and help resolve some connection problems.
