1 Plug one end of the phone cable (1) into the modem port on the computer. 2 Plug the other end into the wall jack (2). ! Your computer does not work with party lines, cannot be connected to a coin-operated telephone, and may not work with multiple telephone lines or a private branch exchange (PBX). Some of these connections may result in excess electrical current and could cause a malfunction in the built-in modem. If you connect a telephone cable coming through a splitter, the modem or connected device may not work properly. To set up a dial-up connection to the Internet ! The following procedure applies to models with a built-in modem only. 1 Click Start and Control Panel. 2 Click Network and Internet. 3 Click Network and Sharing Center. 4 Click Set up a new connection or network. 5 Click Set up a dial-up connection and Next. 6 Follow the on-screen instructions. Using Your VAIO Computer > Using the Network (LAN) n 61 N Using the Network (LAN) You can connect your computer to 1000BASE-T/100BASE-TX/10BASE-T type networks with a LAN cable. Connect one end of a LAN cable (not supplied) to the network (LAN) port on the computer or the optional docking station and the other end to your network. For detailed settings and devices required for LAN access, ask your network administrator. ! You cannot access LAN networks if you disable the network (LAN) port in the BIOS setup screen. To enable the port, follow the steps and the tip in Disabling Built-in Devices (page 125). . You can connect your computer to any network without changing the default settings. When your computer is attached to the optional docking station, you need to select which network (LAN) port to use. Follow the on-screen instructions. Using Your VAIO Computer > Using the Network (LAN) n 62 N ! Do not plug a telephone cable into the network (LAN) port on your computer. If the network (LAN) port is connected to one of the telephone lines mentioned below, high electric current to the port may cause damage, overheating, or fire. -Home (intercom speakerphone) or business-use telephone lines (multi-line business telephone) -Public telephone subscriber line -Private branch exchange (PBX) Using Your VAIO Computer > Using the Wireless LAN n 63 N Using the Wireless LAN The Wireless LAN (WLAN) allows your computer to connect to a network through a wireless connection. The WLAN uses the following IEEE 802.11a/b/g/n standard, which specifies the type of technology used. See the specifications to find out about the configuration of your computer. ! You cannot access wireless networks if you disable the wireless LAN function in the BIOS setup screen. To enable the function, follow the steps and the tip in Disabling Built-in Devices (page 125). WLAN standard Frequency band Remarks IEEE 802.11a 5 GHz - IEEE 802.11b/g 2.4 GHz The IEEE 802.11g standard provides higher-speed communications than the IEEE 802.11b standard. IEEE 802.11n 5 GHz/2.4 GHz On models compliant with the IEEE 802.11b/g/n standard, only the 2.4 GHz band can be used. Using Your VAIO Computer > Using the Wireless LAN n 64 N Notes on Using the Wireless LAN Function General notes on using the wireless LAN function . In some countries, using WLAN products may be restricted by the local regulations (e.g. limited number of channels). Before activating the WLAN function, read the wireless LAN regulations guide carefully. . The IEEE 802.11a standard and the IEEE 802.11n standard are not available on ad-hoc networks. . The 2.4 GHz band used by wireless LAN compatible devices is also used by other various devices. Although technologies to minimize interference from other devices that use the same band are employed on wireless LAN compatible devices, such interference may cause lower communication speed, narrower communication range, or broken wireless connections. . The communication speed and range may vary depending on the following conditions: . Distance between communication devices . Existence of obstacles between devices . Device configuration . Radio conditions . Ambient environment that includes existence of walls and materials of such walls . Software in use . Communications may be cut off depending on radio conditions. . Actual communication speed may not be as fast as the one displayed on your computer. . Deploying WLAN products compliant with different standards that use the same band on the same wireless network may reduce the communication speed due to radio interference. Taking this into consideration, WLAN products are designed to reduce the communication speed to ensure communications with another WLAN product if it is compliant with a different standard that uses the same band. When the communication speed is not as fast as expected, changing the wireless channel on the access point may increase the communication speed.
