Selecting Wired LAN or Wireless LAN

You can select the method for connecting the machine to computers, etc. You can select wired LAN, wireless LAN, or wired LAN + wireless LAN as the connection method.
Connecting to the main network using wired LAN is called "wired LAN (main line)" and connecting to another network using wireless LAN is called "wireless LAN (sub line)."
The IP address for wireless LAN (sub line) is set in <IP Address Settings> in <Sub Line Settings>. Setting the IPv4 Address of the Sub Line

Selecting Wired LAN + Wireless LAN

When wired LAN + wireless LAN is selected, you can connect to a wired network and a wireless network.
  <Preferences>  <Network>  <Select Interface>  select <Wired LAN>, <Wireless LAN>, or <Wired LAN + Wireless LAN>  <OK>
If you selected <Wireless LAN> or <Wired LAN + Wireless LAN>
When you set <Sleep Mode Energy Use> to <Low>, enable <Compensate for Network Comm.>. If <Compensate for Network Comm.> is not enabled, the wireless LAN cannot be used during sleep mode. <Sleep Mode Energy Use>
When <Compensate for Network Comm.> is enabled, power consumption is higher than when <Sleep Mode Energy Use> is set to <Low>.
The settings of <Wireless LAN Settings> are cleared.
You cannot set wireless LAN as the main line and wired LAN as the sub line.

Cautions When Using the Sub Line

Register the port number of functions to use to the firewall settings of the sub line, as required. Configuring the Firewall of the Sub Line
The DNS server and WINS server settings cannot be used at the same time as the main line.
<DNS Server Address Settings> and <Proxy Settings> in <Sub Line Settings> can only be used for specific system data communication. When using a DNS server or proxy server for the sub line for applications other than system data communication, register the addresses and port numbers to use with the sub line in the settings of the main line.
