Then, check if proper security modes are selected on the Security tab. For details on the security modes, see the help file on the Bluetooth Utility software. The data transfer speed is slow The data transfer speed depends on the obstacles and/or the distance between the two devices, but also on the radio wave quality, the operating system or the software used. Try to move the computer or try to place the two devices closer. 130130nN Troubleshooting I cannot communicate with the other device although the distance between both devices is within 10 meters . The data transfer distance can be shorter than 10 meters depending on existing obstacles between the two devices, on radio wave quality, on the operating system or the software used. Try to move the computer or to place both devices closer. . If the device with which you want to communicate is already communicating with another Bluetooth device, it may not be found or it may not be able to communicate with the computer. . Check that the Bluetooth functionality of the device with which you want to communicate is on. See the other device's manual for more details. I cannot connect to service supported by target Bluetooth device Connection is only possible for services also supported by the computer with the Bluetooth functionality. For more details, see the help file on the Bluetooth Utility software. I cannot connect to a Bluetooth device by specifying its IP address on a Personal Area Network (PAN) The Bluetooth utility uses Dynamic Host Configuration Protocol (DHCP) to assign IP addresses to active wireless devices. If you specify a fixed IP address for the device to which you want to connect, the utility cannot assign a dynamic IP address to the device and fails. Do not specify IP addresses when using a PAN. I cannot use the Bluetooth functionality when I log on to my computer as a limited user The Bluetooth functionality may not be available to users with limited rights on the computer. Log on to the computer with a user with administrator rights. 131131nN Troubleshooting I cannot connect to a Bluetooth device in Personal Area Network User mode If the device to which you want to connect supports Bluetooth communication in Personal Area Network User mode only, you cannot establish a connection from your computer. I cannot use the Bluetooth Utility software when I switch a user If you switch a user without logging off from your system, the Bluetooth Utility software will not work successfully. Make sure to log off before switching a user. To log off from your system, click Start and then Log Off. 132132nN Troubleshooting Troubleshooting Wireless LAN I cannot use the Wireless LAN functionality Check if the WIRELESS or WIRELESS LAN switch is turned on and the WIRELESS LAN indicator is lit. The Wireless LAN Access Point and your computer cannot communicate . Check if the WIRELESS or WIRELESS LAN switch is turned on and the WIRELESS LAN indicator is lit. . Check if the power of the Access Point is turned on. . Check if the Access Point is displayed in the Available networks window. . To check this, click Start and then Control Panel. . Click Network and Internet Connections. . Click the Network Connections icon. . Right-click the Wireless Network Connection icon and select Properties. . Select the Wireless Networks tab. . Check if the Access Point is displayed in Available networks. . Connection availability is affected by distance and obstructions. You may need to move the computer away from obstructions or neared to any Access Point you may be using. 133133nN Troubleshooting The data transfer speed is slow . The maximum communication speed can vary depending on the obstacles or the distance between the communication devices, the radio waves, the operating system or the software you use. Remove the obstacle or make the distance between the Access Point and your machine smaller. . It is possible that your Access Point communicates at the same time with another Access Point. Read the manual of the Access Point. . If several computers communicate with the same Access Point, the concentration may be too high. Wait a few minutes and try to access again. . If a Wireless LAN device using the IEEE802.11g standard communicates with a device using the IEEE802.11b standard, then it is normal that the speed reduces. Devices using the IEEE802.11g standard are 5 times faster than the ones using the IEEE802.11b standard. I cannot access the Internet . Check the settings of the Access Point. See the manual of the Access Point. . Check if the computer and the Access Point are communicating. . Make the distance between the Access Point and your machine smaller. 134134nN Troubleshooting I cannot use a Wireless LAN network Check if the Wireless Zero Configuration service is active. To check the status of the Wireless Zero Configuration service 1 Click Start and then Control Panel. The Control Panel window appears. 2 Click the Performance and Maintenance icon. 3 Click the Admini...
