How to Change Wireless Adapter Power Saving Mode in Windows 11
The wireless adapter power saving mode in Windows 11 controls how much power your laptop or PC sends to its Wi-Fi card. Windows 11 turns on a power-saving setting by default, which can slow down your internet speed or drop your connection after the computer wakes up from sleep.
You can fix slow Wi-Fi and stop random drops by changing this setting to Maximum Performance in the Device Manager. Keeping your Wi-Fi card at full power uses slightly more battery, but it gives you a much faster and more stable internet connection.
Open Control Panel , navigate to Power Options, and adjust the Wireless Adapter Settings within your chosen power plan’s advanced settings. Alternatively, use the powercfg command in Windows Terminal with administrator privileges to set your desired mode.
What Is Wireless Adapter Power Saving Mode?
Wireless adapter power saving mode in Windows lets users choose how much energy the Wi-Fi connection consumes, balancing battery life with network speed.
Power Saving Options
| Mode | What It Does |
|---|---|
| Maximum Performance | Best Wi-Fi speed, uses more power. (Default when plugged in) |
| Low Power Saving | Good balance between speed and saving power |
| Medium Power Saving | More power saving but may reduce speed. (Default on battery) |
| Maximum Power Saving | Saves the most power but Wi-Fi may slow down |
How to Change Power Saving Mode via Control Panel
Adjusting the power plan inside the Control Panel offers a direct path to tweaking this behavior. Doing this balances network throughput against remaining battery capacity. Opening the Control Panel, switching to small or large icons, and clicking Power Options reveals the active plan.
- Open Control Panel : Press Win+R on your keyboard. Type
controland press Enter. Switch the view to Small icons or Large icons. Click Power Options. - Choose your active power plan: Look for the plan you are using (like “Balanced”). Click Change plan settings next to it.
- Open advanced settings: Click Change advanced power settings.
Find Wireless Adapter Settings: Scroll down and expand Wireless Adapter Settings. Then expand Power Saving Mode.- Pick your preferred mode: Choose from the dropdown menus for On battery and Plugged in options. For example, select Maximum Performance for best Wi-Fi speed. Click OK to save your changes.
How to Change Power Saving Mode Using Commands
Managing the wireless adapter power saving mode through Windows Terminal (a command-line interface for running shell commands) provides precise control over network performance. Launching Windows Terminal with administrative privileges remains necessary for executing these commands successfully. This approach grants granular management over hardware power states.
Open Windows Terminal as administrator: ⚠️ Admin privileges required. Right-click the Start button and select Windows Terminal (Admin) or search for "Windows Terminal" and open it as administrator.
Copy and paste a command: Choose one of the commands below based on your preferred power saving mode. Paste it into the terminal and press Enter.
For Laptop on Battery:
Running on battery power allows configuring the wireless adapter power saving mode to maximize longevity or prioritize maximum throughput. Maximizing battery duration requires executing the command 'powercfg /SETDCVALUEINDEX SCHEME_CURRENT 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1 12bbebe6-58d6-4636-95bb-3217ef867c1a 0'.

Desktop systems or plugged-in laptops benefit from tuning the wireless adapter power saving mode to favor network performance over energy conservation. Setting the low power saving profile while connected to AC power involves running the command 'powercfg /SETACVALUEINDEX SCHEME_CURRENT 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1 12bbebe6-58d6-4636-95bb-3217ef867c1a 0'.

Summary
- Balance speed and battery life: Choose a power saving mode that fits what you need. Do you want faster Wi-Fi or longer battery life?
- Changing settings is easy: Use the Control Panel or Windows Terminal to make changes.
- Know what each mode means: More power saving means less Wi-Fi performance.
- For laptops: You can set different modes for when on battery or plugged in.
- Learn more: Check Intel’s official guide on wireless power management.
Wireless adapter power saving modes balance Wi-Fi speed and battery life. Modifying these profiles happens through the Control Panel or Windows Terminal. Aggressive power throttling degrades Wi-Fi performance, while laptops maintain separate configurations for battery and AC power.
