Helped me troubleshoot my router
Im not sure how accurate the meter is but I was more concerned with relative strength of the routers signals in my home. The meter told me that the router was working and also where in the house the weak or strong areas were. That was all that I wanted and NW MM worked just fine. I had previously tried Network Analyzer, which is also a great program, but having the meter needle move as I walked around the house was a much move effective solution for my problem.
