Hm? SO the guy wasn't telling me the truth.

I was told by the Livermore CA Comcast Center that before the firmware is pushed, a macro is run to test weather the device is leased or owned. The leased devices are pushed the firmware updates. Customer owned devises are not.

My Motorola SBG6580 was provisioned in December 2011 running firmware version 3.0. I bought this unit and on my monthly invoice it states that it is "Docsis 3 Owned Mdm". The SBG6580 started disconnecting several times over the course of several days last week (beginning around 1/20/2012).

From the date the modem/gateway was first provisioned (Dec 2011) Comcast system(s) never pushed ANY firmware update(s) (it should have at least updated the device to ver. 3.1). I can only guess that the Comcast "system" was trying to push an update but once it saw that my devise was customer owned immediately reset my modem, thus the cause of my intermittent connections. This must have been the cause of the intermittent disconnect issues as reflected in my SBG6580 log report.

My solution was to set the SBG6580 device into bridge mode and pursue a firmware update at a later date until ver. 3.30 is ready for release. So far, in bridge mode using a Dlink Dir-655 wireless N router, my connection has been rock solid.

The dual band function in the SBG6580 does provide a better wireless stream (especially when I have multiple wireless devices connected). I also have a separate VOIP SIP device that functions in both configurations (bridged and un-bridged) but am told that with the Docsis 3.1 firmware version, it would drop my SIP calls and/or may not even connect to the outside SIP server). Firmware ver 3.3 supposedly fixes this.

For anybody who needs a step-by-step guide for setting the SBG6580 into bridge mode go to this link: Getting a Motorola SBG6580 into “Bridge” mode on TimeWarner Wideband »fascinated.fm/post/2379188731/ge···-mode-on

Emailing We_Can_Help@cable.comcast.com resulted in a call back w/i 24 hours. I still did not get a satisfied reply other than the reason for my recent drops was line noise. It was also confirmed (at least by this service rep) that Comcast will not update the firmware for any customer owned devices.

I am sure that if Comcast wanted to, they could code my device as leased and issue me a credit each month on my invoice for the lease fee. So, the best I can determine is as a result of my SBG6580 being coded as an "owned" not leased device, the systems prepares to do an update but immediately sends a rest command, thus causing my frequent intermittent drops. So far, in bridge mode, none of these drops have occurred.

firmware is pushed to the device upon sync to the CMTS.....at that point it does not know whether its customer owned or not.....it sees what firmware it had, and then if the cmts has a more current file, its pushed....modem reboots, locks, and then ya do what ya have to do...
