Have you ever encountered such a problem, when you use your iPhone at home, as soon as you use AirPods to listen to music at the beginning, or listen to music with other Bluetooth headphones, your WiFi speed becomes very slow, what is the reason for this?
A fan asked me today, she encountered a very strange problem at home, as long as you use Bluetooth headsets, the WiFi at home becomes very slow, which is the kind that can be clearly felt, and because of this problem, I have asked the operator to come and check it several times, but it still hasn't been solved.
I didn't figure it out at the time, so I asked her to use the speedtest to test the network speed, the network speed and broadband matching, there was no problem at all, but at the beginning of the connection to the Airpods, the network speed was directly attenuated by nearly half, and now, I found the problem.
I asked her if there were two WiFi at home, one was 2.4GHz, the other was 5GHz, and the current connection was 2.4G, and I expected that this was the problem of signal interference.
Theoretically, Bluetooth and WiFi will interfere with each other in the 2.4GHz frequency band, and when turned on at the same time, the throughput of Bluetooth data will drop sharply, and in serious cases, there will even be devices that cannot be connected, pairing failures, and WiFi will also have frequent problems, intermittent signal interruptions, network restrictions, and network speed slowdown.
In fact, the solution is very simple, the current home routers are basically dual-band, including 2.4GHz and 5GHz, you just need to connect your mobile phone to the WiFi with the word "5GHz".
Finally, it needs to be explained that Apple's Airpods support Bluetooth 4.2 and 5.0, and there is a great improvement in the problem of interfering with WiFi signals in the 2.4GHz band, if you use other Bluetooth headphones, remember not to connect to the 2.4GHz WiFi band.
In fact, the WiFi frequency band is very important, and the router sets two frequency bands to avoid signal interference.
