What Is Bluetooth Interference?
Bluetooth technology is a type of wireless connection that is used in a lot of devices such as headsets, earphones, mouse, keyboards, etc. It works by connecting your device with a smartphone or a computer to enable the transfer of data between the two devices.
To accomplish this, Bluetooth sends signals over a 2.4GHz radio frequency covering short distances.
The problem starts when other devices nearby are also using the same frequency. Baby monitors, microwaves, wireless speakers, other Bluetooth devices and receivers, as well as Wi-Fi are some of the examples of devices with frequencies that can clash with each other.
In turn, your Bluetooth device may experience different types of disruptions such as disconnections, static sounds, and audio delays. These disruptions are called Bluetooth interference.
Aside from frequency clashes, there are many other causes of interference that would be discussed later in this article.
Verify That Your Phone Has Bluetooth, and Turn It On
Pairing a phone to a car audio system varies depending on the phone and the infotainment or audio system's setup. Most of these steps translate in one way or another regardless of what type of phone you have and the car you drive. The first step, in any case, is to make sure that you have the right tools.The 3 Best Car Stereo Systems of 2022
The first step to pairing a phone with a car stereo is to verify that your phone has Bluetooth.
Turn on your phone, if it's turned off, and verify that you have Bluetooth. The Bluetooth symbol looks like a capital B overlaid with an X. If you're familiar with runes, it's a bind rune made up of "hagall" and "bjarkan," owing to the Scandinavian origin of the technology. If you see this symbol anywhere in your phone's status area or the menus, your phone probably has Bluetooth.
While going through the menus, make a note of where the "make phone discoverable" and "search for devices" options are. You'll need those in a little while. Most phones remain discoverable for a couple of minutes, though, so you don't have to activate that yet.
If your head unit or phone doesn’t have Bluetooth, there are other ways to get Bluetooth in your car.
Best FM Bluetooth transmitter
Although it works for voice calls, this FM transmitter is best suited to music streaming. You can see which station you’re tuned to and easily find a new one.
Today we’ve seen how to fix interference issues between WiFi network and Bluetooth devices, which may be really frustrating. Especially that Bluetooth is currently coming back in with BT speakers, smartbands and IoT devices in general.
I hope you’ll find those advises useful 😉

Bluetooth Speaker Interference
Bluetooth speakers use the 2.4 GHz band to send and receive data. They share the samebandwidth with other appliances such as Wi-Fi devices, microwave ovens, and fluorescentlighting. When these appliances transfer data simultaneously, you may experience cut-outs from the speakers, otherwise referred to as interference. It causes inconvenience but is relatively easy to fix.
While Bluetooth speakers are equipped to counter interference, too many devices may be toomuch to handle. You can do the following to minimize Bluetooth speaker’s interference:
- Ensure the batteries have enough charge
- Use third-party apps to check devices causing interference and switch them off if necessary
- Reset your Bluetooth devices regularly
- Switch other devices like the Wi-Fi router to different frequencies such as 5GHz that doesn’t interfere with the speakers
- Ensure you’re within the range of your Bluetooth speakers
- Update your Bluetooth speaker’s app to fix bugs
- “Forget” and pair your Bluetooth speakers again with audio devices like your phone or computer again.
- If the interference is still there, seek technical support.
Choose the Bluetooth Device to Pair
If your phone successfully finds your car's hands-free calling system, it shows up in the list of available devices. In this case, the Toyota Camry's hands-free calling system is called "hands-free" on the list.
After selecting the device, enter a passkey or passphrase to pair the devices. Each car comes with a preset passkey, which you can typically find in the user manual. If you don’t have the manual, set a passkey from your infotainment system’s phone settings menu. And if that doesn’t work, your local dealer may be able to provide you with the original passkey.
Many Bluetooth devices use "1234," "1111," and other simple passkeys by default.
If you entered the correct passkey, your phone will pair with the hands-free calling system in your car.
If it doesn't, repeat the steps you already took and make sure that you put the correct passkey in. Since it's possible to change the default passkey, the default might not work in some pre-owned vehicles. In that case, pair your phone again after changing the passkey to something else.
Q: Do Bluetooth car kits have a voice-command option?
A: Yes, most of them have this option, but it has to be activated. The process is simple, and you’ll only need to push a few buttons. However, it’s probably better to set the voice commend before the ride so you don’t get distracted from driving.
Q: Will a Bluetooth car kit drain my car’s battery?
A: Possibly. If you have a kit that connects to the cigarette lighter, you want to make sure it’s turned off before you get out of the vehicle. Not all cars can cut off the power automatically, so you’ll have to do it manually to avoid battery issues.
Q: Is it difficult to connect a Bluetooth car kit to the stereo?
A: No. You can either connect it to the AUX-in audio jack by using an audio cable or directly. Another option is connecting the kit through the jack that produces a radio signal. Once plugged in, it will become visible on your phone’s Bluetooth list.
Bluetooth and WiFi interference problem
I recently noticed that when I’m using my Zenbook working on WiFi having Bluetooth speaker connected in the same time and listening to music, my WiFi speed decreases significantly. To show you the scale of the problem, here is the basic Internet tracert I performed when BT was turned off:
and here is the same tracert, but when listening to music via BT speaker:
35 ms without BT to 2532 ms with BT. Nice! That’s 72 times worse! Plus the request didn’t even complete with BT turned on. Something is wrong here.
The same happened on my Huawei P8, when I had my MiBand 2 connected via Bluetooth.
