The Dropped Connections
One of the most frustrating issues on a Windows 11 laptop is when the system automatically drops your Wi-Fi connection to save battery life. If you leave your laptop idle for a few minutes while reading a long document, you might return to find that your SSH sessions have timed out, your large file downloads have failed, and your chat applications have disconnected. Windows 11 does this aggressively under its default power management plan, assuming that if you aren’t moving the mouse, you don’t need a persistent network connection.
How to Disable Network Adapter Power Management
To force Windows to keep the Wi-Fi adapter powered on at all times, you must dive into the Device Manager and override the power settings for the specific hardware component.
1. Right-click the Start button on your taskbar.
2. Select Device Manager from the power user menu.
3. In the Device Manager window, look for the category labelled Network adapters and click the small arrow next to it to expand the list.
4. Locate your primary Wi-Fi adapter (it will usually have “Intel,” “Realtek,” “Broadcom,” or “Wi-Fi” in the name, e.g., “Intel Wi-Fi 6 AX201”).
5. Right-click your Wi-Fi adapter and select Properties.
6. A new dialog box will appear. Click the tab at the top labelled Power Management. (Note: If this tab is missing, your system uses Modern Standby, which handles power differently. See the next section).
7. If the tab is present, untick the checkbox labelled Allow the computer to turn off this device to save power.
8. Click OK.
Fixing Disconnects on Modern Standby Laptops
If the Power Management tab is missing, your laptop uses “Modern Standby.” You need to change how the system handles network connectivity when the screen turns off.
1. Open the Start menu, type Settings, and press Enter.
2. Go to System > Power & battery.
3. Look for a setting related to “Network connection in standby.”
4. Ensure it is set to Always (rather than “Managed by Windows” or “Never”). This guarantees the Wi-Fi stays active even when the screen goes dark to save power.
