Sets the number of times TCP will retransmit an individual data segment before aborting the connection.
Example
Do not run below example code just to see what happens next. Many methods seriously affect your system. Always make sure you actually understand what the method and the code do.
# define the arguments you want to submit to the method
# remove values that you do not want to submit
# make sure you replace values with meaningful content before running the code
# see section "Parameters" below for a description of each argument.
$arguments = @{
TcpMaxDataRetransmissions = [UInt32](12345) # replace 12345 with a meaningful value
}

Requirements
To use Win32_NetworkAdapterConfiguration, the following requirements apply:
PowerShell
Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.
If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.
Operating System
Win32_NetworkAdapterConfiguration was introduced on clients with Windows Vista and on servers with Windows Server 2008.
Namespace
Win32_NetworkAdapterConfiguration lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.
Implementation
Win32_NetworkAdapterConfiguration is implemented in CIMWin32.dll and defined in CIMWin32.mof. Both files are located in the folder C:\Windows\system32\wbem:
explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\CIMWin32.mof
