I was on a 400/40 plan (And often got 475/43 in real use), and then after upgrading to the gigabit plan, my modem reprovisioned, and now my speedtest is 700/5. I understand I will not get the full gigabit down speed because my modem is a Motorola MB8600 (which comcast says can only reach speeds of about ~930 down), but I should be getting at least the 40 up that I had on my previous provisioning. None of the equipment changed, and I have restarted my modem multiple times, and done a factory reset twice letting it reprovision twice with no change the the ~5mbit upload speeds.
I have already used the comcast automated assistant, and it just wants me to upgrade my modem because my modem does not support the speed of my current plan.
I understand that my modem does not support the full download speed, but I was already getting the 40mbit upload speed before the plan upgrade. I just want that 40mbit back.
Any suggestions? Comcast support, if you are listening, can you check that you are sending my modem the right provisioning file?
I am posting my connection stats below to show it's not a signal problem either:

I wanted to provide an update for anyone in a similar situation. The Hitron CODA56 immediately solved the issue. So it would seem the MB8600 isn't compatible (or isn't allowed to be configured properly) for the xfinity gigabit service config profile. The following is a summary of my experience in case anyone else has the same issue:
1) Had a Motorola MB8600 working great at 400/40 with real world speeds of 475/47.
2) Decided to upgrade to gigabit (1000mbps down / 100mbps up) because there was a good offer available, and accepted the offer.
3) The MB8600 did not automatically reprovision, so I restarted the modem an hour later. And it updated the provisioning profile at that point.
4) The real world speed tests were 740/5. Only 5mbps upload was unacceptable to me.
5) Googled for hours trying to see if there was a way to make the MB8600 work, and tried multiple restarts and full factory resets, allowing it to download a new provisioning file. No improvements or changes.
6) Tried the automated assistant feature on the xfinity portal, but it would only tell me that my equipment was not able to reach the speeds of my plan.
7) Gave up and ordered a Hitron CODA56. Received it.
8) Used the mobile app to swap the equipment, providing it the new modem MAC address.
9) After about 15 minutes and a couple of restarts, it was up and running and I now get over 1100/120, very happy.
If this applies to your situation, I know it's not free, but just save time, buy a modem on the recommended equipment list.

If this is a mid split / "next gen speeds" support issue where the MB8600 can't (or isn't allowed) to work with the network upgrades, I can accept that. But how can I confirm my area supports next gen before buying a new modem?

I went ahead and ordered a Hitron CODA56 which should arrive later today to see if this is an MB8600 compatibility issue. I need at least 20mbit upload speeds but I will never use equipment rented from comcast.
