蓝牙可能会干扰 Wi-Fi，但仅限于2.4 GHz频段。蓝牙设备 operates at this frequency, which is also used by smart home protocols like Zigbee and Thread, as well as microwaves. 当多个设备如智能恒温器、冰箱和安全系统争夺带宽时，蓝牙设备可以给您的 Wi-Fi 连接带来压力，导致延迟和数据包丢失。这可能会损害像游戏或视频通话这类敏感任务的性能。

2.4 GHz频段对于这些设备来说最为理想，因为它能更好地穿透厚墙，并在更长的距离内正常工作，尽管速度较慢。然而，较新的设备采用 Wi-Fi coexistence logic to operate simultaneously without slowing each other down. 大多数智能手机、笔记本电脑、电视以及其他现代客户端设备 operate on the 5 GHz or 6 GHz bands provided by dual-band or tri-band router setups.

Instead of turning off Bluetooth devices, try using a Wi-Fi analyzer app like Network Scanner to find optimal channels within the 2.4 GHz band, such as channels 1, 6, and 11. Using shielded cables near your router and spreading devices further apart can also help. In dense environments, Wi-Fi extenders or a mesh network may be necessary. In most cases, Bluetooth devices no longer pose a significant risk to home Wi-Fi performance.
