No Service After Modem Reboot and Area Upgrade

Early in the morning there was schedule maintenance and I was hoping for an and upgrade of our 1200/35 to 1200/200.  Checked today and the site shows 1200/200 is my new service level.  Speed tests show I'm still getting  35.  So I decide to reboot my modem and router.  Now my modem is not connecting to the internet and showing the following errors.

    Time Not Established   Critical (3)   SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;CM-MAC=<redacted>;CMTS-MAC=<redacted>;CM-QOS=1.1;CM-VER=3.1;

Hi there, @user_flyinace2000. Most areas only offer this speed option if renting our xFi Complete services, but I would love to assist with updating the bootfile for your modem if it's not reflecting properly for you. A provisioning signal should do the trick if your account qualifies, which can be sent from our end.

Thanks message sent.  Related, I fixed my connectivity issue (it was DNS), but would love help getting the 200mbps upload speed instead of the 40 I getting now. Thanks!
