CM3000 Firmware problems

My customer-owned NETGEAR CM3000 is currently running firmware V6.01.04. NETGEAR’s current firmware table lists V5.01.02 as the Comcast-deployed firmware for the CM3000. I’m experiencing repeated intermittent disconnects/latency events and would like this escalated to the appropriate provisioning/network team to determine whether V6.01.04 can be rolled back to V5.01.02 for diagnostic purposes.
