The first, Home, tab offers the basic network parameters of the device. The first page of this tab provides a Wizard for a step-by-step setup of each basic parameter.
The LAN page contains Ethernet-related settings. You can choose the speed of the network port and the connection type (with appropriate parameters).
The Wireless page is where you chose the operation mode: client or access point. After that you can set up such parameters (of the access point) as SSID, channel number, protocol (802.11b/g, 802.11g), encryption method, etc.
On the Device page you specify how the DSM-G600 is going to be identified on the network.
