Motorola MT8733 Randomly Reboots... FIX NEEDED!!!!!!!

Hello @howie14w, thank you for providing all the steps you've taken to get this resolved through your manufacturer. If there is an issue with your device, I don't have a way to directly help resolve your owned modem or a contact for Motorola to provide. I would love a chance to work with you and see if we can get to the bottom of this issue on the Xfinity side of things. Have you tried troubleshooting your modem through the Xfinity app by chance? Can you please verify your coaxial cable is finger tight at both your device and wall plate? Do you have any splitters along your line with only one device connected? Or are there any kinks or visible damage long your coax line? 

@howie14w I saw that comment on email only. I cant see on my OP. If you can get me info, I too will contact AG's

@MickeyMao​ I am in Maryland and contact them at this website, [Edited: "Solicitation"]

Most states probably have a consumer protection division.

Hilarious! Xfinity removed a government website address for consumer protection as “solicitation.”

Meanwhile, a tech at Xfinity gave me a phone number for Motorola support I hadn’t seen or tried before…it turned out to be for Motorola CANADA.

They referred me back to the U.S. where no one answers the phone…ever!

So Xfinity can’t help because it is my modem, the people who sold me the danged modem can’t help because I bought it nine months ago, the the maker of the modem seems to have closed its support department.

wow this is amazing! no one has put it forward yet. Thanks @zandor60657 

I'd be more inclined to describe it as a "train wreck" than "amazing" lol.  Alas, you might be looking at getting a new modem sooner than you expected.

Given that you're having performance/reliability issues you might want to rent an xFinity gateway for a bit, especially if you can do so without signing up for a 1 or 2 year contract.  That way there's no question who's problem it is if the tech can't figure out if it's Comcast's network or the modem/router since both of them will be their problem.

Also Comcast is in the middle of rolling out increased upload speeds to customer owned equipment.  So far only 3 models are supported.  2 Hitron modems and a Netgear CM2050V modem.  The CM2050V is only supported if you have phone service.  So far no combo modem+router units like your Motorola MT8733 are supported.  We'll get a lot more clarity on what will and won't support the new increased upload speeds over the next few months I think.  I'm guessing no Motorolas.  Personally I prefer separates (so modem + router or mesh kit rather than an all-in-one modem/WiFi router) so I can upgrade the modem and router separately (and use business class routers & WiFi access points), but the all-in-one combo units do work well if your home isn't too big and they make less clutter.

I did a factory reset, and it seems like that was the only thing to fix the Clock Sync error. It hasn't randomly reboot since. Its only been a couple days. considering that I've been a comcast costumer for a decade and I bought my own equipment so that way I could save money and have more control of MY NETWORK, I might  as well get paid for all the work I do for comcast on my own system. comcast needs to get their stuff together.
