Using the speed check Wifi  to test the relationship between Bluetooth and Wifi. Does Bluetooth really impact Wifi signal? Have you ever met a weak Wifi connection’s signal situation while listening to music via Bluetooth speaker ? Or maybe your Wifi speed becomes worse when you turn on your Bluetooth mouse or keyboard ? What is the reason for this circumstance? Let’s find out in this article below.

What is Bluetooth and Wifi?

Before finding the influence between two popular forms of connection, we need to know what Bluetooth and Wifi are.

Speed check Wifi: resolve Bluetooth and Wifi interference

Bluetooth is a wireless communication technology but works in a short-range. It allows devices such as mobile phones, computers, laptops and peripherals to transmit data or voice wirelessly over a short distance. The benefit of Bluetooth is to replace the cables that normally connect devices, while still keeping the communications between them secure. It allows Wireless data transmission between mobile device and computer, transfer files between computers or share network connection via Bluetooth as well. Moreover, Bluetooth is developed additionally to connect peripheral devices such as headphones, smartwatch, mouse, gamepad, printer. Especially, Bluetooth is applied in businesses such as: positioning, medical equipment, barcode dredging, traffic control equipment.

Wifi standing for Wireless Fidelity, is a wireless Internet connection, using radio waves to transmit signals. This type of radio wave is similar to a telephone, television and radio wave and on most electronic devices today such as computers, laptops, phones, tablets ... can connect to Wifi. Nowadays, digital technologies have developed dramatically, therefore, people work, study or entertainment online frequently. Therefore, the Wifi also became important in our lives. 

Speed check Wifi: Bluetooth affects Wifi signals

So, how Bluetooth affects Wifi signals? Is there interference between these two popular forms of connections ? Conducting the speed check Wifi  to find the answer.

Maybe you do not know but both Wifi and Bluetooth may work on the same frequency, 2.4 GHz frequency. Bluetooth is designed to work on 2.4 GHz and also most popular Wifi routers (e.g. TL-WR845N router) are configured to broadcast their signal on the same frequency by default. In fact, Bluetooth uses frequencies with wavelengths shorter than Wifi. Since it is a technology with a certain standard, when manufacturing electronic devices, manufacturers must adhere to general technical standards to create compatibility between products. 

Overall, wireless networks like Bluetooth and Wifi, apart from the frequency, operate on different channels. However, a channel can be imagined as a highway – the wider the lane is, the more people can go on it. On the other hand, the more people drive on the lane, the slower they go. The same happens with Wifi channels – if there are many Wifi networks in our neighborhood working on the same Wifi channel, our network may work slower.

To test this fact, you can run the speed check Wifi to check network connection before and after turning on Bluetooth. You can use website test like MySpeed, Speedtest or GTmetrix.

After turning on Bluetooth headphones, using the speed test internet you will get worse results. Depending on the type of your routers, the speed of Wifi is affected by Bluetooth somewhat. 

Some symptoms of wireless interference you can notice: 

  • Device does not connect or stay connected but can not surf the internet

  • Connection is slow and signal strength  is low, loading page is slow

  • Some problems with Bluetooth audio like skip, stutter, cut off, or has static or buzzing

  • Pointer movement is erratic or jumpy

How to solve the interference?

So, how to stop Bluetooth slow down your Wifi?  These general steps can help you achieve a cleaner, stronger Wifi signal somewhat:

  • Using devices connecting Wifi closer to your Wifi router because the closer your router is, the stronger Wifi signals are. At the same time, bring the Bluetooth devices that are connecting to each other closer together. 

  • Avoid using your wireless devices near common sources of interference which operate at the same frequency 2.4 GHz, such as power cables, microwave ovens, fluorescent lights, wireless video cameras, and cordless phones.

  • Using the modern router like 802.11n and the 802.11ac routers which use the 5 GHz band instead. This avoids Bluetooth and Wifi working at the same frequency leading to interruption. If your Wifi router supports both bands, it might help to connect more of your Wifi devices to the 5GHz band. Some dual-band routers manage this for you automatically. Nowadays, many new routers are developed to solve this interference. 

  • Setting your Wifi router to use a different Wifi channel, or have it scan for the channel with the least interference. This scan can be conducted automatically on startup or when reset.

If you're using USB 3 or Thunderbolt 3 devices with your computer, you can limit their potential to interfere with nearby wireless devices and have a better speed check Wifi results by these ways:

  • Using a high-quality, shielded USB and Thunderbolt 3 cable 

  • Move your USB 3 or Thunderbolt 3 devices including any USB hubs far away from your wireless devices as far as possible.

  • Avoid placing USB 3 or Thunderbolt 3 devices on top of your Mac Pro, Mac notebook, or Mac mini which make interference signals. 

  • Turn off any unnecessary USB 3 devices that aren't in use.

Additionally, you should avoid physical obstructions in the path of your wireless signal to have a good Wifi signal. For example, a metal surface between your Bluetooth mouse and computer could cause the mouse to perform poorly which annoys you. The speed check Wifi also is bad if having a metal-reinforced concrete floor between your Wifi router and Wifi device. You should consider this factor. 

  • Low interference potential material : wood, glass, and many synthetic materials

  • Medium interference material: water, bricks, marble

  • High potential: plaster, concrete, bulletproof glass

  • Huge interference potential: metal

Conclusion

Today we’ve seen the relationship between WiFi network and Bluetooth devices, which may be really frustrating as well as how to fix interference issues. Especially that Bluetooth is currently more popular with Bluetooth speakers, smart bands and others devices in general. With the help of the speed check Wifi we realize this clearly. Wifi is not only affected by Bluetooth but also Microwave ovens. You can read more at Microwave oven is killing your Wifi
