I don't have a machine to test this on at present, but one thing to note is that the article specifies the WMI namespace (the default is CIMv2), so at the very least you'd need to do something like this: import wmi c = wmi.WMI (namespace="WMI") Once you've got the namespace, you should be able to use the standard syntax to query the -- frankly, unwieldy -- WMI class: for result in c.MSNdis_80211_ReceivedSignalStrength (active=True): print result.Ndis80211ReceivedSignalStrength The machine I'm on is Win2k and non-wireless so I don't have the class available to check.
