Make sure the device you're trying to pair with isn't turned off, low on battery power, or in standby mode (also called sleep mode).

Make sure the device is within wireless range of your computer, typically within 6-9 feet for most Bluetooth enabled devices, or within 100 feet for a wireless network Wi‑Fi device. If you aren't sure if the device is in range, try moving it closer to your computer. If there is a wall between the device and the computer, try putting the device and computer in the same room.

Make sure there are no other devices interfering with the wireless device, such as microwave ovens, cordless phones, or other wireless devices.

If your computer uses an external Bluetooth or Wi‑Fi adapter, make sure the adapter is working correctly and is properly attached and installed.

If Bluetooth capability is integrated into your computer, make sure the Bluetooth radio transmitter is turned on. This might be combined with a switch that also turns your wireless network receiver on and off. Many laptops have an external switch for turning this on and off. If you aren't sure how to turn this on, check the information that came with your computer.

Make sure the device is discoverable. When a Bluetooth enabled device is set to be discoverable, it sends out radio signals to advertise its location to other devices and computers. If you aren’t sure how to set your device to be discoverable, check the information that came with your device or check the manufacturer’s website. Some devices (such as a wireless mouse or keyboard) have a button on them you need to push, while others (such as a Bluetooth mobile phone) might have a setting in their software menu you need to select to make them discoverable.

If you're trying to add a wireless network device, it must be configured for your wireless network before you can add it to your computer. If you're not sure how to do this, check the information that came with the device or go to the manufacturer's website.
