| The Wi-Fi speed is slow or disconnects when the computer is not connected to a power supply |
Problem
When the computer is not connected to the power supply and the user uses Wi-Fi to browse online or watch videos, they feel that the Wi-Fi speed is slow or the Wi-Fi disconnects constantly.
Cause
This happens because the computer enters power saving mode when it is not connected to a power supply. In this scenario, there is a chance that the wireless network adapter cannot sustain the power supply, resulting in the Wi-Fi speed slowing down.
Solution
- Connect your computer to a 5 GHz Wi-Fi network.
- If the Wi-Fi speed of your computer is slow or it disconnects, connect your computer to a power supply.
- Check whether the PC Manager version on your computer is running the latest version. If not, update PC Manager to the latest version.
- Check whether the Wi-Fi driver on your computer is running the latest version. If not, use PC Manager to update the Wi-Fi driver and Bluetooth driver to the latest version.
