Most wireless networks use 802.11b/g technologies, more commonly referred to as Wi-Fi (short for Wireless Fidelity). Bluetooth is another wireless networking technology that is increasing in popularity. Bluetooth signals usually have a maximum range of about 10 meters, making the technology less useful than Wi-Fi for creating wireless computer networks. However, Bluetooth is a great way to connect other kinds of devices, including:
 | Bluetooth radio waves can cause slight interference with 802.11b/g Wi-Fi signals. To reduce interference and improve the performance of both Wi-Fi and Bluetooth gear, try to position Bluetooth and Wi-Fi antennas as far apart from each other as possible. |
Follow these steps to set Bluetooth discovery options:
1. Right-click the Bluetooth icon in the Windows system tray and choose Advanced Configuration from the menu.
2. In the Bluetooth Configuration screen, click the Accessibility tab.
3. Select the Let Other Bluetooth Devices Discover this Computer option.
If you enable discovery, other Bluetooth computers will be able to see your computer. However, you can control access using the Allow menu below.
4. Click the Discovery tab.
5. Select the Look for Other Bluetooth Devices option and choose how often you want to perform a check.
6. Click the Apply button and then click OK to close the Bluetooth Configuration dialog box.
| If you are going to be using your computer in public, you should turn off Bluetooth discovery (both incoming and outgoing) to prevent strangers from accessing your computer. Bluetooth sniffer programs — programs that scan for and identify active Bluetooth signals — are becoming increasingly popular. In fact, if you don't need your Bluetooth radio you should disable it or (if possible) remove any USB or cardbus Bluetooth adapters. |
