Setup procedure
This section explains how to setup a wireless LAN interface.
Two methods of setting up wireless LAN are available: automatic setup by using WPS (Wi-Fi Protected Setup), and manual setup by entering required information such as SSID.
To configure the wireless LAN settings manually, display the screen for Wireless LAN configuration, and then use the following procedure:
For details about how to specify wireless LAN settings from the control panel on the printer, see Wireless LAN Configuration.
For details about how to specify wireless LAN settings automatically, see Configuring a wireless LAN using Easy Setup.
Select [802.11 Ad-hoc Mode] when not using the infrastructure mode.
When [802.11 Ad-hoc Mode] is selected in Communication Mode, select the channel for [Ad-hoc Channel]. Set a channel that matches the type of wireless LAN being used. For details about setting the Ad-hoc Channel, see Wireless LAN Configuration.
You can specify either "WEP" or "WPA2" for Security Method.
To connect the machine to an access point, use the infrastructure mode.
In the infrastructure mode, the channel varies according to the access point settings.
To connect the machine directly to a computer over a wireless LAN, use the ad-hoc mode.
The WPA2 authentication is not available in the ad-hoc mode. Only an unauthenticated connection or WEP authentication is available in this mode.
The WPA2 authentication has two authentication methods: the IEEE802.1X [WPA2] authentication and [WPA2-PSK] authentication using a pre-shared key with the access point or destination. The WPA2 authentication is available in the infrastructure mode only.
For details about the WPA2 authentication, see "Configuring IEEE 802.1X Authentication", Security Guide.
If you select the [WPA2] option for Security Method, select one of the following: [WPA2-PSK] or [WPA2]. If you select [WPA2-PSK], enter your PSK. If you select [WPA2], authentication settings and certificate installation settings are required. For details about setting methods, see "Configuring IEEE 802.1X Authentication", Security Guide.
If you use Wireless LAN EasySetup/Direct Connection, an access point that is compatible with WPS is required.
If a wireless LAN connection is made using [Push Button], there is a time limitation for pushing each button or performing the equivalent function on the machine and access point. If the button on the access point is not pressed within 1 minute after the one on the machine has been pressed, the connection may not be successfully completed. If the button on the access point is pressed prior to pressing the one on the machine, the time limitation varies according to the specification of the access point. If a wireless LAN connection is made using [PIN Code Method], there is a time limitation on the access point side.
For details about how to specify wireless LAN settings from the control panel on the machine, see Host Interface.
To connect to multiple Wireless Direct-compliant devices by using the machine as a simple access point, use the Direct Connection: Group Owner mode. Up to nine devices can be connected. Non-Wireless Direct-compliant devices can be connected too.
In Direct Connection: Group Owner mode, the devices connected to the machine cannot communicate with each other. The devices can only communicate with the machine.
In Direct Connection: Group Owner mode, the machine can communicate by Ethernet and wireless LAN simultaneously.
Use Direct Connection mode to connect the machine to another device one-on-one through the Wireless Direct function. If this mode is enabled, the machine cannot connect to non-Wireless Direct-compliant devices.
