Usage Precautions

Notes on Security when Using Wireless LAN

(Important information on customer rights (maintaining privacy))

The advantage of using a wireless LAN over a LAN cable is that, because information is exchanged using radio signals, you can easily connect to the network if you are within range of the radio signals. A disadvantage of this is that within a certain range, the electromagnetic signals can pass through barriers such as walls, so that if security countermeasures are not implemented in some way, problems such as the following may occur.

• Communicated data can be intercepted

A third party may be able to receive wireless transmissions without authorization, and they could obtain personal information from these transmissions such as IDs, passwords, or credit card numbers, or they could intercept the contents of personal e-mail messages.

• Unauthorized access to the network

A third party could access an individual or intra-company network without permission and carry out any of the following activities.

• Retrieve personal data or other secret information (information leakage)
• Pose as another user and send inappropriate data (impersonation)
• Overwrite the contents of intercepted data and resend it (falsification)
• Introduce a computer virus which could cause data loss or system crashes (damage)

Initially, the possibility that such problems could occur through settings concerning the security of the wireless LAN product and by using the product are decreased, because the wireless LAN card and the access point have security measures to deal with these problems. We recommend that you use this product after making security settings using your own judgment and assuming full responsibility, and with your full understanding of problems that may occur if you do not make any security settings.

Notes on Setting SSID (Service Set Identifier)

For protection of security, note the following precautions when setting the SSID.

• Change the SSID from the default setting.
• Do not set texts by which the owner can be identified as the SSID.

Notes on Setting Cryptographic Key

For protection of security, note the following precautions when setting the cryptographic key.

• Avoid using dictionary words as much as possible.
• Combine meaningless alphanumeric characters and symbols.
• Use texts consisting of at least 13 characters or more, or 20 characters or more if possible.

Connectable Products

This product can be connected to the following products in accordance with IEEE 802.11b, 802.11g, and 802.11n.

• Computers with a built-in wireless LAN function
• Access points

However, available communication modes may be restricted by the specifications of the connected device.
