New recommended modem not achieving upload speed

In response to emails from xfinity, I upgraded my cable modem to the recommended Hitron CODA56. According to xfinity, I should be getting up to 200 Mbps upload speeds per my current Internet plan. But I am still seeing the same old 40 Mbps upload speed when I run a speed test.

Both upstream and downstream LEDs are blue, indicating successful channel bonding.

Is there something I need to do at my end or xfinity needs to do at their end to enable the faster upload speed?

Comcast came through. I'm getting the high upload speeds as of today.

Comcast has been nagging me for months about how one of these 5 modems or gateways would rock my upload world. I spent $140 on the CODA56 and see no upload speed increase.
Emphasis mine:

Faster internet speeds now available

Upgrade your internet equipment today!

Good news
You can now enjoy up to 5-10x faster upload speeds and smoother connections with your current Xfinity Internet package.

Easy next steps
Your internet equipment is unable to deliver these new speeds, but here’s a list of compatible devices to purchase:

• Hiltron Technologies CODA
Hiltron Technologies CODA56
• NETGEAR CM3000
• NETGEAR CBR750
• ARRIS SURFboard G54

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

Exact same results as I just replaced a perfectly fine Motorola MB8611 DOCSIS 3.1 to supposedly increase my upload speed which was supposed to work with my service.  No change to the ~40/41 Mbps upload.

Was a CODA56 like the OP.  Several restarts and it's working as expected.

Oh okay @user_i3x88u! I’m glad to hear it’s working after restarting the modem. On our end we’ve been finding most modems have just needed a provisioning or reset signal sent for them to update with the new upload speeds.

@XfinityAldrik​ Same problem.  Got email to increase upload speed.  Got hitron coda.  Not sure if xfinity has done all the needed provisioning. But my upload speed is still around 4 and download 100.  Should be 100 upload and 200 download.  Help would be appreciated.

Restarting the modem a few times seems to have forced some additional firmware to get applied and has since resolved the issue.

I've been chatting with agents and it turns out Comcast is having trouble either finding or sending the right bootfile for my modem. They're working on it & I have a ticket number.

I had to unmark the post that was marked as the solution. I have restarted my CODA56 many times without success. There seems to be trouble on the Comcast side. An agent told me

I noticed something that was off with the way the modem was listed on my end, and I think this would be the cause of the slower speeds. It looks like the bootfile we had for your modem doesn't show registered as one with next generation speeds, so this would essentially block the modem from getting the higher upload speeds. I attempted get that corrected on my side, but it wasn't successfully updating. Not to worry though, I have worked with one of our repair teams to help us get this corrected and they are working to get that updated for us! I don't have a timeline just yet on when that will be completed, but typically we see a turnaround time of 24-72 hours. A ticket was created on our end to be able to track this, so I will be keeping an eye on this for you to provide updates once available!

I am having the same issue!  Upgraded to CODA56 and customer service is now telling me I do not have access to the 200MBPS service.  Spent all morning on the phone and chat with them!!!  I've received several emails telling me to upgrade my modem for 5-10x faster upload speeds!

@jmunzer Did they tell you your area (node) was not yet provisioned for next gen midsplit? I was told that my area has been provisioned. If yours has not, maybe find out when they expect to upgrade it.

Xfinity will come out.  Hopefully, that will do it.  Otherwise, need to return and try the coda 56.
