USB ports on your computer can cause WiFi and Bluetooth issues
The problem of USB 3.x or USB-C devices affecting Wi-Fi is only found in the 2.4 GHz band, making it easy to use connections in the 5 GHz band. with which some USB 3.x devices generate interference in the 2.4 GHz band this can have adverse effects on WiFi or Bluetooth, two of the most used wireless connections.
If we are among those who have encountered this problem and we see that when we disconnect the USB device, everything works again, We can try several things to solve it like:
- Use cables high quality, some cheaper cables may not have the necessary "shielding" to prevent radio interference.
- Use high quality USB 3.x or USB-C devices. Some cheaper ones can give problems.
- As long as we do not use this device, it is best to unplug it and turn it off.
- If you have a long cable, we can move the peripherals away from the computer.
- We may try to connect the device to another port further away from the WiFi or Bluetooth antenna of the computer or laptop.
- Use WiFi 5 GHz as much as possible and our router is compatible.
- Reduce interference from other devices in the 2.4 GHz band away from microwaves, cordless phones, and baby monitors.
- Move the router to a better position to get more signal.
- Use a USB hub to move devices away from the computer.
