Alternatives to Network Magic

I recently changed my router from a CISCO Linksys to D-Link. Consequently Network Magic (which I have found to be superb) ceased to operate. Upon enquiry with CISCO I learned that they no longer support NM and as far as I can establish it doesn't work with other than CISCO networks. Does anyone know of a similar product that will work with Windows and D-Link.

Thnx in advance
