CM1000 not getting Gigabit speed with Xfinity

The Xfinity tech showed upwards of 1 Gig from the wall but I can't get a gig connected directly to the CM1000 modem. Please help.

Furrye38,

 

The ISP provider in this case Comcast came home yesterday and checked the quality of the signal coming inside the home. The was able to remove some issues with some interference and was able to demonstrate through his equipment that the signal was strong and he was gettting more than 1 gig connection for download.

 

And he connected the modem directly to the incoming RG6 Coax. While debugging by connecting my laptop directly to the modem ethernet out I also did the following

 

(a) I rebooted the modem several times and tried the connection

(b) Factory reset

(c) Each time waited a few mins (powered off, removed the coax connection, removed power input)

 

Both did not solve the issue.

 

I had asked the ISP to reprovision the modem before the Tech came in yesterday and that was not successful either. The only thing I have not done is to as them to reprovision after the tech came to visit. I will try that today and repost and see if it that makes a difference.

 

Would love for someone more knowledgeable than me to look at the settings I posted and logs and see if there is something they see glaring that I might be able to work with Comcast to fix.

 

Thanks again to everyone who is helping me resolve this !

Seems like the ISP has checked everything. Seems like the the modem itself maybe the problem. I would get another modem put in place to see if the problem continutes...

    Do the logs indicate any issues?

     

    Also I will see a reprovision helps from Comcast.

        Thanks for the post. Read the post indicated two issues

         

        (a) T3 issues with line or modem (have to check)

        (b) Issues with modem rebooting (that surely needed a modem replacement).

         

        Helps me narrow it down. Thanks again for your help. I will see what my ISP says about T3 timeout issues.
