According to Electronicshub, Bluetooth and Wi-Fi are two popular means of wireless communication that are primarily operating in the unlicensed 2.4 GHz ISM Frequency Band (Industrial, Scientific, and Medical). The main challenge to using these two technologies simultaneously is Interference between them. Along with these two, any other technologies that are operating in the same 2.4 GHz range (such as Microwave Ovens, and cordless phones) are prone to interference from each other when they operate in close vicinity.
Here are some common issues that you might face when there is interference between Bluetooth and Wi-Fi.
Connection Drops
The first and most common problem with Bluetooth Interference with Wi-Fi is an unstable connection. Be it your mouse/keyboard or headphones, your device will frequently disconnect or try to reconnect all the time.
Static Noise
This problem is significant if you are using Bluetooth headphones in proximity to other 2.4 GHz devices, such as a Wi-Fi router. The static or buzzing sound is a strong indicator that there is interference between Bluetooth and Wi-Fi systems.
Audio Issues
When Bluetooth interferes with Wi-Fi (or vice-versa), your headsets might act all janky. They get random inputs even though you did not press a button. They skip tracks or increase/decrease volume on their own.
Increased Latency
There is already an issue of Bluetooth latency with our headsets or mice. But when there is interference with Wi-Fi, then there is a chance that this latency increases.
Drop In Signal Strength
When you use a Bluetooth device to close a strong Wi-Fi signal, then the signal strength of either or both devices might drop significantly.
Low Speed
Bluetooth is already a slow form of communication. You might not notice this when you are using Bluetooth Mice or Keyboards. But if there is interference and you are trying to send a file or photo, then this drop in speed will severely affect you.
