Netgear CM3000 lag and instability

I’ve been trying to get my modems firmware rolled back to the one previously used before V6.01.04, it’s a commonly reported problem and a fixed hasn’t been pushed yet. Xfinity chat support keeps telling me they can only get me their modem and that they don’t control firmware which is a blatant lie as Internet service providers are the ones solely pushing firmware updates. @Xfinity Support

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

user_oebj4y Welcome to our community forum! Thank you for reaching out so we can help with your firmware questions. When it comes to customer-owned equipment, we can send the latest firmware that the manufacturer provides. Although we don't have the option to roll back to a previous firmware version, I would recommend reaching out directly to the manufacturer to see if they can help. Have you reached out to the manufacturer directly?
