Netgear CM1100 and "Gigabit" tier

I'm paying for gigabit speed with my supported and recomended docsys 3.1 modem but have never seen the 960mbps speed I'm paying for.

 

Everytime I speak with support I get a different story.

 

I fully understand the difference between wifi and wired and my speed tests are from a pc connected directly to the modem - NO router or wifi involved and using new CAT 5E eithernet cables as well.  The best I see has bee 360mbps but the average is prob closer to 300mbps.

 

I have also seen dramatic slow downs to the point of no connectivity, they replaced the line outside and inside to the modem.  When that was done those slowdowns stopped BUT I still do not get anywhere near the 960mbps I am paying for.

 

They say the signal to the modem is what it should be yet nobody can tell me or explain to me why some channles are locked and others are not.

 

Is anyone using the CM1100 and suceesfflly getting 960mbps with it that can share what "Downstream Bonded Channels" are locked?  In my case all are locked execept 32.

 

"Upstream Bonded Channels" 1-5 are locked but 5-8 are not.

 

Thank you in advance.

Please post a screenshot of all the channels up and down. On the upstream, only 3-4 will be locked because that is all they offer currently.

Thank you for your reply.  Yes, I have been through that post. 

 

They threaten me with a $70 fee for a visit if the problem is not theirs, I'm very comfortable/confident it is not my issue.  So I took the recent desperate step of using THEIR modem (TG3482G) and my speeds were a little better but not as close as I feel they should be to the 960mbps I'm paying for. 

 

I'm testing with a MacBook pro connected via ethernet directly to the cable modem - no router or wifi involved.  I typically do use a desktop connected to the router via ethernet.

 

I have not summoned the intestinal fortitude to call and explain this to them as this has been an ongoing issue for two months, and have too busy since installing the new modem.

 

I would ideally like to use mine still but using this as a troublshooting measure for them.

 

Thanks

This is from september when I was having the same issue.  When I was looking at the issue this past friday I had the same channels locked and not locked.
