Troubleshooting for wireless network
If problems occur while using the machine on a network, check the following:
For information on the access point (or wireless router), refer to its own
user's guide.
• Your computer, access point (or wireless router), or machine may not be
turned on.
• Check the wireless reception around the machine. If the router is far from
the machine or there is an obstacle, you might have difficulty receiving the
signal.
• Cycle the power for the access point (or wireless router), machine, and
computer. Sometimes cycling the power can recover network
communication.
• Check whether firewall software (V3 or Norton) is blocking the
communication.
If the computer and the machine are connected on the same network and it
cannot be found when searching, firewall software might be blocking the
communication. Refer to the user's guide for the software to turn it off and
try searching for the machine again.
• Check whether the machine's IP address is allocated correctly. You can
check the IP address by printing the network configuration report.
• Check whether the access point (or wireless router) has a configured
security (password). If it has a password, refer to the access point (or wireless
router) administrator.
• Check the machine's IP address. Reinstall the machine driver and change the
settings to connect to the machine on the network. Due to the
characteristics of DHCP, the allocated IP address could change if the
machine is not used for a long time or if the access point has been reset.
Register the product's MAC address when you configure the DHCP server on
the access point (or wireless router). Then you can always use the IP address
that is set with the MAC address. You can identify the Mac address of your
machine by printing a network configuration report.
• Check the wireless environment. You might not be able to connect to the
network in the infrastructure environment where you need to type in a
user's information before connecting to the access point (or wireless router).
• This machine only supports IEEE 802.11 b/g/n and Wi-Fi. Other wireless
communication types (e.g., Bluetooth) are not supported.
• The machine is within the range of the wireless network.
• The machine is located away from obstacles that could block the wireless
signal.
Remove any large metal objects between the access point (or wireless
router) and the machine.
Make sure the machine and wireless access point (or wireless router) are not
separated by poles, walls, or support columns containing metal or concrete.
