Looking for a freeware utility to track wifi uptime

[Old and In the Way]

I've been searching around the innertubes for a simple piece of software that logs the wifi state of my connections. Everything I see seems to be based on actively pinging some website to see if there's a connection. What I want is something that logs status of the actual wifi network in my home. When my signal goes into trouble or offline, my icon in the system tray changes its state to signify that the wifi signal is faulty or not available. I'd simply like to have a logging utility that copies that event to a csv file that I can use to monitor performance over the long term. Any suggestions?
