Server 2008 R2 Powershell version 4 cannot use Get-Net* (anything) commands

Brand new to PS here.

I have a new install of 2008R2 and have updated to Powershell 4 by installing Windows Management Framework 4.0. The system has DotNET 4.5.1 on it as well.

I am trying to run a script for setting IP which is part of the example shown in the following blog:

So far I have run into a brick wall as I am unable to break the code for using the Get-NetAdapter command.

In the example, the following is shown:  $ipif = (Get-NetAdapter).ifIndex  New-NetIPAddress -IPAddress $ipaddress -PrefixLength $ipprefix -InterfaceIndex $ipif -DefaultGateway $ipgw

When running the script, PS errors with"Get-NetAdapter : The term 'Get-NetAdapter' is not recognized as the name of a cmdlet, function, script file, or operable program"

I found that by using "$ipif = Get-Command -Module NetAdapter -InterfaceIndex" , I get nothing. When I use the PowerShell ISE, no error is given either and the Intellisense feature is no help.

I have executedGet-Module on my system and this is the output:

I would welcome suggestions, comments and/or pointers for the correct direction in which to travel.

Thanks in advance
