A common cause for a desktop losing its internet connection after sleep is that power-saving features in Windows may be disabling the network adapter. To fix this, you can adjust power management settings for your network adapter to prevent it from being turned off during sleep.
Here's a more detailed explanation and troubleshooting steps:
Understanding the Problem:
Power Saving:
Windows has power-saving features designed to conserve energy, including turning off devices like network adapters when not in use.
Sleep Mode:
When a computer goes into sleep mode, it often disables power to certain components to save energy, including potentially the network adapter.
Re-enabling:
When waking from sleep, the network adapter may not be immediately re-enabled, causing a temporary or permanent loss of internet connection.
Troubleshooting Steps:
1. Adjust Power Options:
Open the Control Panel and go to Power Options.
Click on Change plan settings for your current power plan.
Click on Change advanced power settings.
Expand Wireless Adapter Settings > Power Saving Mode and set it to Maximum Performance for both "On battery" and "Plugged in".
Click Apply and OK.
Restart your computer.
