The Dropped Downloads
Windows 11 utilizes aggressive power management profiles on modern laptops to maximize battery life. One of the ways it saves power is by engaging “Modern Standby” when you close the lid or when the screen times out. During this sleep state, the operating system frequently cuts power entirely to the Wi-Fi adapter. While this drastically reduces battery drain, it is incredibly frustrating if you started a massive file download or a long software compilation over an SSH session before walking away. When Windows goes to sleep, the Wi-Fi drops, completely terminating your active network tasks.
Keeping the Connection Alive
To ensure your network tasks complete and stop Windows 11 from automatically disconnecting your Wi-Fi when the device enters sleep mode, you must adjust the advanced power plan settings for your wireless adapter.
Press the Windows Key, type Edit power plan, and hit Enter. In the window that appears, click the small blue text link that says Change advanced power settings. A new “Power Options” dialogue box will open. Scroll down through the list until you find Wireless Adapter Settings. Click the small plus (+) icon next to it to expand it, and then expand the Power Saving Mode sub-menu beneath it. You will see options for “On battery” and “Plugged in.” Click on the current setting (which might be “Medium Power Saving” or “Maximum Power Saving”) and change both dropdown menus to Maximum Performance. Click Apply and then OK. By forcing maximum performance, you instruct the kernel to never cut power to the Wi-Fi chip, ensuring your network connection remains completely stable even when the screen is off.
