Unfortunately, it began to exhibit flaky behavior within weeks of purchase/installation. The most frustrating aspect has been the black hole for my time that dealing with a parade of dysfunctional service individuals and counterproductive emails.
Modem works fine but Internet provider and Netgear support said it was working fine with steady green internet light on and it actually needed a reset to finally connect.
Works well with WOW 500MB plan. WOW tech support helped me switch from their modem to the CM1200 with no problems. I use the EERO for Wi-Fi which is running great. Will pay for itself in just a few months!
