C3000-100NAS LATENCY ISSUES EVERY MINUTE

Before we start with the silly 'did you turn it on and off'' question, I just want to let you know that I'm a Network engineer with my Cisco CCNP in Routing/Switching

Anyways, I'm seeing some massive latency spikes take place, which begun in the past 1.5 months, in which I have changed NOTHING in my home network.   Comcast says they are clean, and to verify this statement I'm one of their routers for this problem.

Has anyone else seen latency spike approx occur every 1 minute on their C3000-100NAS?   

**WHAT I'M SEEING**

This is good...
