-===== Change the Settings with a PowerShell Script ===== 
- 
-This is the fastest fix. The script makes the same changes as the manual steps below, on the adapter that connects to the Spider: 
- 
-  * Turns off Energy-Efficient Ethernet, Green Ethernet, and the other standard power-saving properties. 
-  * Clears **Allow the computer to turn off this device to save power** for the adapter, and for the USB hubs it is connected through. 
-  * When the PC is plugged in: turns off USB selective suspend, sets sleep and hibernate to **Never**, and sets closing the lid to **Do nothing**. 
- 
-Close EDM and do not run a test while you run the script. 
- 
-  - Find the name of the adapter that connects to the Spider (see the first part of **Turn Off Power Saving on the Adapter** below). Use the name in **Network Connections**, for example **Ethernet 2**, not the device name. 
-  - Click **Start** and type **PowerShell**. Right-click **Windows PowerShell**, click **Run as administrator**, and click **Yes**. 
-  - Type this line, with your adapter name between the quotes, and press **Enter**: ''%%$name = 'Ethernet 2'%%'' 
-  - Copy the block below, paste it into the PowerShell window, and press **Enter**. 
-  - If PowerShell shows red error text, change that setting with the manual steps below. 
-  - Restart the PC. 
- 
-<code powershell> 
-Get-NetAdapterAdvancedProperty -Name $name | Where-Object RegistryKeyword -match '^\*?(EEE|AdvancedEEE|EnableGreenEthernet|GreenEthernet|SelectiveSuspend|PowerSavingMode|SipsEnabled|ULPMode)$' | Set-NetAdapterAdvancedProperty -RegistryValue 0 -NoRestart 
-$ids = @(); $id = (Get-NetAdapter -Name $name).PnPDeviceID 
-while ($id -and ($ids.Count -eq 0 -or $id -like 'USB\*')) { $ids += $id; $id = (Get-PnpDeviceProperty -InstanceId $id -KeyName DEVPKEY_Device_Parent).Data } 
-Get-CimInstance -Namespace root\wmi -ClassName MSPower_DeviceEnable | Where-Object { ($_.InstanceName -replace '_0$') -in $ids } | Set-CimInstance -Property @{ Enable = $false } 
-powercfg /setacvalueindex SCHEME_CURRENT 2a737441-1930-4402-8d77-b2bebba308a3 48e6b7a6-50f5-4782-a5d4-53bb8f07e226 0

-If your company does not allow PowerShell scripts, or you want to change the settings yourself, use the manual steps below. You can also use them to undo any change the script made.
