A Wireless LAN uses radio waves instead of cables to send and receive data. Because radio waves usually pass through walls and other obstructions, the following problems may arise if you do not configure wireless security settings.
Information leakage
Information such as IDs, passwords, credit card numbers, and e-mail content may be seen by an unauthorized 3rd party.
Unauthorized network access
Damage to or alteration of data and/or system configurations by viruses or other malware.
Impersonation of legitimate network users, resulting in data theft.
Theft of sensitive or confidential data.
To minimize the possibility of these threats, it is recommended that you check the available features of this printer, wireless access points, and other equipment that uses the Wireless LAN, and configure security settings for the Wireless LAN.
If the network area provides poor radio environment
Where radio wave conditions are bad, the network may not function due to interrupted or failed connections. When checking the wireless LAN signal and the access point, follow the procedure below to improve the situation:
Position the access point nearer to the machine.
Clear the space between the access point and machine of obstructions.
Move radio wave generating appliances, such as microwaves, away from the machine and access point.
For more information about access point radio wave conditions, refer to the access point manual.
For details about Wireless LAN security settings such as WEP key, WPA, and IEEE 802.1X, see Security Guide.
