Latest firmware update for Zoom 5370 modem

I would like to get the latest firmware update 5.5.10.2 for my Zoom 5370 modem.

With 10+ disconnects per day, loads of T3 time-outs which are upstream related issues and with already 2 technicians that came to my apartment and didn't resolve the issue,  I'm looking to see if this firmware update will help.  Zoom tech support has mentioned this patch has addressed an issue of excessive upstream grants.

    Currently the Zoom 5370 modem does have the current firmware supported for our network for version 5.5.10.1. We are testing but have not release or approved the 5.5.10.2 version to work on our service. When it is confirmed test by our engineers to be compatible with our network it would be pushed out automatically to the modem.

    The upstream signal levels are not showing problems currently but the logs do show the time outs, there are some power adjustments however that may be related to the problem. Are you having the issues with the disconnects more at specific times of day or is it random?

    EdwardH,

    Thanks for your reply.

    My disconnects occur pretty randomly throughout the day.  The internet will go out from anywhere from a few seconds to a few hours.

     I ended up buying a drop amp Electroline ERA-4100 Reverse Path Amplifier.  This thing drops Upstream by 10 dBmV.  If you have access to my modem signals, you'll see my upstream is now in the 34-38 dBmV range,  Before it, my upstream was around 48 dBmV and would disconnect me if it reached 51 dBmV.   My modem was basically yelling back to Cox, and this workaround acts similar to using a microphone when speaking in an auditorium.  Of course, its simply a band-aid to a bigger issue but it actually keeps me online.  My internet will only go out for a few seconds to maybe a minute if anything.

    I had two technicians come out but they didn't really fix the issue.  I suspect I need a more knowledgable tech, perhaps a tier-3 tech.  Whats interesting is that the customer service reps on the phone seem way more knowledgable than the technicians that come out.

    I'm looking forward to the update, hoping it will fix some things!

    Thanks
