The connection method cannot be switched between a wired LAN and a
wireless LAN.

required to have the machine switch to your selection.
Selecting Wired LAN or Wireless LAN(P. 15)
The SSID of the wireless router to be connected is not displayed in the access
point list.

Checking the SSID and Network Key(P. 29)
● If the SSID of the wireless router is hidden (using a stealth mode
*
), set the SSID to be visible on the wireless
router.
*
A mode that disables the SSID auto-detection of other devices.
● Check whether the machine is properly installed and ready to connect to the network.
When the Machine Cannot Connect to the Wireless LAN(P. 618)
The machine dials up to an unintended connection destination (if a dialup
router is connected to a network).
● If a dialup router does not need to pass broadcast packets, set the dialup router so that the broadcast
packets will not pass. If the dialup router needs to pass broadcast packets, check whether the settings are
correct.
● If a DNS server is located in an external network, set the IP address to be connected, not the host name, even
if connecting to the devices that are on the network that is connected to the machine.
● If a DNS server is located on a network that is connected to the machine and the information about the
devices that are connected to an external network is registered to the DNS server, check whether the settings
are correct.
When the Machine Cannot Connect to the Wireless LAN
Check the status of your computer.
● Have the settings of the computer and the wireless router been completed?
● Are the cables of the wireless router (including the power cord and LAN cable)
correctly plugged in?
● Is the wireless router turned on?
If the problem persists even after checking the above:
● Turn off the devices, and then turn them on again.
● Wait for a while, and try again to connect to the network.
