My Bluetooth/WiFi connection keeps on dropping. Why is this?

The strength and reliability of any wireless signal can be affected by potential sources of interference. The effects that these sources can have include:

  • A decrease in the wireless range between devices
  • A decrease in data throughput over Wi-Fi
  • Intermittent or complete loss of the wireless connection
  • Difficulty pairing during a Bluetooth device's discovery phase

The potential sources of interference include:

  • Microwave ovens: Using your microwave oven near your computer, Bluetooth device, or Wi-Fi base station may cause interference.
  • Direct Satellite Service (DSS): The coax cable and connectors used with certain types of satellite dishes may cause interference. Check the cable for damage and obtain newer cables if you suspect RF leakage issues.
  • Certain external electrical sources such as power lines, electrical railroad tracks, and power stations.
  • Video senders (transmitters/receivers) that operate in the 2.4 GHz or 5 GHz bandwidth.
  • Wireless speakers that operate in the 2.4 GHz or 5 GHz band.
  • Certain external monitors and LCD displays: Certain displays may emit harmonic interference, especially in the 2.4GHz band between channels 11 and 14. This interference may be at its worst if you have a portable computer with the lid closed and an external monitor connected to it. Try changing your access point to use 5 Ghz or a lower 2.4 GHz channel.
  • Any other wireless devices that operate in the 2.4 GHz or 5 GHz bandwidth (microwaves, cameras, baby monitors, neighbors' wireless devices, and so on). 

To help minimise the effects of this interference, you should If possible, avoid wireless barriers, or change the placement of the Wi-Fi or Bluetooth devices for a clearer signal path. The device's location within building and construction materials used can affect Wi-Fi and Bluetooth. The table below shows common types of barrier material and their potential for interference.

To reduce the effects of interference from other devices, you should try:

  • Change channels on your wireless network.
  • Connect to a 5 GHz wireless network (if possible).
  • Minimize the number of active Bluetooth wireless devices you have connected to the computer or operating in the area.
