The NDis WMI classes expose some information about the vendors that produce the various adapters in our systems

function get-adaptervendor {            
param(            
 [string]$computer="."            
)            
Get-WmiObject -Namespace root\wmi -Class MSNdis_CoVendorDescription `
-ComputerName $computer |            
foreach {            
                
  $id = Get-WmiObject -Namespace root\wmi  `
  -Class MSNdis_CoVendorId -ComputerName $computer `
  -Filter "InstanceName='$($_.InstanceName)'"            
            
  New-Object -TypeName PSobject -Property @{            
    Computer = $_.__SERVER            
    Adapter = $_.InstanceName            
    Active = $_.Active            
    Description = $_.NdisCoVendorDescription            
    Vendorid = $id.NdisCoVendorID            
  }            
}            
}
