Communication Functions 4-8 4 Wireless LAN Modes There are two kinds of wireless LAN modes: Infrastructure mode and Ad Hoc mode. Access Point (Infrastructure) Mode Infrastructure mode refers to a wireless network in which wireless devices communicate with each other through an access point (AP). Wireless devices can communicate with each other or can communicate with a wired network through AP. Ad Hoc Mode Ad Hoc mode refers to a type of network that consists of multiple computers each equipped with a wireless networking interface. Each computer can communicate directly with other wireless enabled computers. Security Measures Since wireless LANs provide data transfer using electric waves instead of LAN cables between communicating devices, a third party can illegally access to and monitor the transmitted information. The following security measures reduce opportunities to receive the threats. Use a combination of the following measures for more secure communications. ADSL modem, cable modem, or similar Access Point To Internet
Operation Manual 4-9 4 See the Notice of Security with Wireless Devices section on page xv. Authentication The following may help you to protect your important data from illegal access. • SSID (Service Set Identifier) “SSID” is a common network name. An SSID acts as a password that is shared with all connecting wireless devices, resulting in preventing access by any device that does not have the SSID. Set a same SSID on the computer and an access point which you are using. To enhance the security, rely on a combination of the SSID and WEP or WPA security. (For details on configuration of the access point, refer to its manual.) • MAC (Media Access Control) address filtering MAC addresses are unique addresses on the network, which are assigned to the computer’s network interface cards. An access point allows access by only devices if their MAC addresses match the addresses in an authentication list used by the access point. Register your MAC address with the access point which you are using. (For more information, refer to the manual of the access point.) To confirm the MAC address of the computer; 1. Click start – All Programs – Accessories – Command Prompt. 2. Type ipconfig/all and press Enter. 3. Confirm the numbers of Physical Address in the Ethernet adapter Wireless Network Connection field. 4. Type exit and press Enter. • WPA (Wi-Fi Protected Access) The computer supports WPA, a wireless LAN security standard increasing the level of data protection and access control compared to WEP (Wired Equivalent Privacy) encryption. To use the WPA security, a WPA-enabled access point is required. To implement user authentication, one of the security enhancements of WPA, an authentication server is needed. For details on WPA features, consult your network administrator or the manual of the access point which you are using.
Communication Functions 4-10 4 Encryption The computer provides the following encryption mechanisms including: TKIP, AES, and WEP. The three techniques allow you to encrypt data to be transmitted, which will make illegal interception more difficult. • To use the WEP functions, your communication partner must support the functions. • To utilize TKIP, the access point which you are using must support TKIP. • To utilize AES, the access point which you are using must support AES. • WEP (Wired Equivalent Privacy) WEP relies on an encryption key that is shared between a wireless device and an access point. The key is used to encrypt data and decrypt the transmitted data. • The computer supports 128-bit and 64-bit WEP keys. • For enhancement of security, the encryption keys should be periodically changed. • TKIP (Temporal Key Integrity Protocol) TKIP provides an improved data encryption, which was weak in WEP. The TKIP encryption automatically generates a new unique encryption key periodically for each device to avoid the same key staying in use for weeks as they do with WEP. • AES (Advanced Encryption Standard) AES is a stronger form of encryption than is found in the WPA protocol and is the security standard approved by US Government organizations.
Operation Manual 4-11 4 Activating the Wireless LAN Antenna To communicate using the wireless LAN, the integrated antenna must be activated. You can enable/disable the antenna by pressing the Fn+F1 ( ) key combination. When the antenna indicator ( ) lights green, the antenna is enabled. When the indicator light is off, it is disabled. Disable the antenna on airplanes and in specific places where radio-susceptible equipment is nearby such as medical and electrical equipment. Electric waves generated from the antenna may affect the performance of the devices and cause malfunction of the devices. When the Wireless LAN of the APM button is set to ON or OFF, pressing the APM button will turn on or off the wireless LAN antenna according to the APM button setting. (For more information, refer to the Using the Advanced Power Management Button section on page 2-9.) Connecting to a Network via an Access Point You can connect the computer to the Internet or a wired network via an access point supporting IEEE802.11b or IEEE802.11g.

Troubleshooting Operation Manual T-1 Troubleshooting This chapter describes how to troubleshoot computer problems. Common Problems Problems with your computer can be caused by something as minor as an unplugged power cord or as major as a damaged hard disk drive. The information in this troubleshooting section is designed to help you find and solve minor problems. If you still have a problem after trying all the suggested remedies in this chapter, contact your dealer or, for users in U.S, call: 1-800-BE-SHARP (237-4277). The problems that you might encounter can be divided into two basic categories: hardware and software. Hardware problems can be further divided into being of an electrical or a mechanical nature. You will know you have a hardware problem if, for example, the screen is blank, or your computer cannot recognize the disk drives. Software problems can occur at several levels. Both your operating system and your software application programs are capable of generating errors and error messages. If you encounter a software error, try to determine if the error message is from your operating system or from an application program, and refer to the appropriate manual for possible remedies. You can also refer to the Windows help program to solve the problem. To access the program, click start – Help and Support. It also gives you troubleshooting tips and an index. Successful troubleshooting is the result of careful observation, deductive reasoning, and an organized approach to solving the problem. If you encounter a problem, begin by performing a careful visual inspection. Check the exterior of your computer first. If no lights are displayed, check the battery charge or power outlet, the plug and power cord, and any power switches that may affect your computer. If your computer has been connected to any peripheral devices, look for loose or disconnected cables. You may also need to check the fuses and breakers in your electric box. A few common problems and suggested solutions are presented in the examples that follow.
