1994 was the year when Bluetooth first came into the consumer market. Since then, the Bluetooth technology has revolutionized how we operate electrical devices in our homes, offices, and outside on a sunny beach.
But convenience causes problems, especially when we are dealing with something so easy to implement and use as a Bluetooth signal.
Once upon a time, we had a single car on a single road. Meaning, the person who owned the car didn’t have to deal with traffic. Fast forward a hundred years and you are stuck in traffic even when your city has built hundreds of roads.
Similarly, nowadays, we have millions upon millions of devices that use Bluetooth technology and millions of other devices that use WiFi technology. But the problem is, WiFi devices and Bluetooth devices both operate within a similar frequency range, which is around 2.4 gigahertz.
But why would they do so?
Because it’s convenient.
Both signals are in essence just a radio wave, and radio waves lie within the, 30 hertz to 300, gigahertz frequency spectrum. But sadly, the usable frequencies range from 2.4 to 5 gigahertz. The congestion caused by the overlapping of similar frequency signals slows down the WiFi connection. Because the WiFi signal emitted by your router is stuck in the frequency traffic and your mobile phone is too far away to reach it.
Manufacturers are taking steps to minimize overlap and interference between network signals.
Within the past decade, new Bluetooth devices are using Frequency-hopping technology. The technology changes the channel a Bluetooth signal is operating on every second. Similarly, we have the 5 gigahertz WiFi signal which operates on a completely different set of channels.
But, like cars and roads, there are still millions of devices that operate on the 2.4 gigahertz frequency band. And unfortunately, the frequency hopping technology does little to minimize interference.
There are a few ways with which you can minimize interference between your Bluetooth and WiFi devices, some of them are detailed below.
Ways To Fix Bluetooth Slows Down WiFi:
1. Change the 2 gigahertz channel
A mobile app called WiFi analyzer can be downloaded to your device. This app allows you to see which channels are more congested, and with this precious information in hand, you can utilize your router’s settings to change its operating channel to something that is less congested. As a result, your 2.4 gigahertz devices will operate on a channel that has less traffic and will move from one device to another with greater ease.
2. Change the operating frequency
The 5 gigahertz band is not only 3600 megahertz away from the 2.4 gigahertz band, but it’s also a lot faster and provides more channels to choose from. If your computer, mobile phone, and router, support the 5 gigahertz technology. Then it’s a very productive idea to change your router’s operating frequency from 2.4 gigahertz to 5 gigahertz.
3. Buy an external WiFi card
It’s a common – WiFi degrading – issue that occurs when you are using your laptop’s WiFi and Bluetooth card both at the same time. This occurs because both cards are extremely close to each other, and as a result interfere with one another when operating on the 2.4 gigahertz band. A simple fix would be buying an external WiFi card and using that card to access the internet.
