Why Does My Bluetooth Keep Disconnecting? 20 Easy Fixes – Tech News Today
Even though Bluetooth technology first appeared in 1999, it’s still unreliable.
Different Bluetooth hardware has varying behaviors with various degrees of success. That creates several common problems: random disconnections, interruptions, dead batteries, and interferences from other devices. Moreover, changing from one device to another is often a hassle.
Let’s discuss why Bluetooth comes with so many shortcomings. Similarly, we’ll see how you can make your Bluetooth hardware work. These devices include smartphones, PCs, headsets, mice, mics, keyboards, car audio, fit bands, smartwatches, and more.
Bluetooth devices skip the need to use more cables and dongles.
Why Does My Bluetooth Keep Disconnecting?
Bluetooth uses the 2.4Ghz frequency band. This is the same frequency most wireless devices use, from baby monitors to smart TVs. Other items employing the 2.4GHz code include fluorescent likes, CFL bulbs, smart home devices, and microwave ovens.
The competition for broadband between WiFi devices and slower Bluetooth connections leaves the latter prone to glitches, disconnections, and interruptions.
Bluetooth keyboards and mice will always have a lag compared to wired models.
Imagine Bluetooth works as person-to-person communication. One person talks (transmitter); the other listens (receiver).
For proper communication, both have to talk nearby and face each other. Also, it works best when there’s no music, noises, or other people talking around them.
But as a summary, here’s a rundown of why your Bluetooth keeps disconnecting:
- Crowded network: The biggest issue is when various protocols compete for 2.4GHz bandwidth. As Bluetooth is generally slower than WiFi, it will suffer disconnections, glitches, and interruptions if several wireless devices are nearby.
- Range: Bluetooth connections have a limited range. Most consumer options are Class 2 Bluetooth, which has a 10m range but may not work beyond 2.5m. Class 3 has a 30m, but may still not work beyond 10m. Lastly, Class 1 works a 100m, but it’s an industrial-only solution.
- Transmit power: Each Bluetooth connection has a transmit power that affects how effective the range is. The more power, the faster Bluetooth can drain the battery. Because most manufacturers use low transmit power, the effective range is much lower than marketing suggests.
- Path loss: The Bluetooth signal degrades as it travels through the air. Obstacles between the receiver and the transmitter further deteriorate the signal.
- Attenuators: signal attenuators include rain, humidity, walls, windows, panels, columns, tables, chairs, etc. In essence, it could be any structure between the transmitter and the receiver made of glass, metal, wood, or concrete.
- Moving around: Bluetooth travels around 2400 and 2483.5 MHz to offer a balance of range and output. Because of that, signal strength can drop off when you move around. It causes interruptions like choppy audio.
- Incompatibility: Bluetooth is backward compatible, but there’re exceptions across the three categories: Classic, Smart, and Smart Ready.
Bluetooth speakers should be as close as possible to the source.
