Stop Windows Turning Off Your Network Adapter (Power Saving)

Disable adapter power management so Wi-Fi doesn't disconnect every time the PC sleeps.

WindowsadapterPower & SleeppowershellLow risk
Run Disable-NetAdapterPowerManagement -Name "Wi-Fi" in an admin PowerShell to keep the adapter fully powered.

01Command

Command
$ Disable-NetAdapterPowerManagement -Name "Wi-Fi"

02What it does

Windows saves battery by allowing the network adapter to sleep when idle, but on many machines the adapter then fails to wake properly, leaving the network disconnected after sleep or dropping the connection during downloads. Disable-NetAdapterPowerManagement turns off those power-saving features for the named adapter. Check the exact name first with Get-NetAdapter.

03Risk

RiskLow risk
RequirementsRun PowerShell as administrator. Replace "Wi-Fi" with your adapter name from Get-NetAdapter.
!Warning: On battery-powered laptops this slightly increases idle power draw — you can re-enable it any time with Enable-NetAdapterPowerManagement.

Undo
$ Enable-NetAdapterPowerManagement -Name "Wi-Fi"
