Sync timing synchronization failure – failed to acquire QAM QPSK will be the focus of this write-up.
In recent times, the synchronization failure notion has been on the increase, hence affecting the network and computer speed.
Apart from that, sync timing synchronization failure can also fail to acquire QPSK/QAM symbol timing. This will lead to experiencing out-of-spec upstream power.
Furthermore, it will affect the downstream power which will suddenly become weak, hence giving rise to latency issues, packet loss, speed issues, random connection disconnections, and automatic modem reboots.
If you’ve been facing these issues currently, there is every tendency to sync timing synchronization failure has occurred.
Let’s consider some troubleshooting tips to rectify it.

What should you do to fix the issue?
1. Confirm if there are surplus coax cable splitters
This is a self-technique any user can apply to get good internet connectivity. You just need to check for any extra coax cable splitters.
It can result in modem reconfiguration and also the elimination of a proper system. For those making use of the coax cable splitters, ensure they’re of higher quality and not too much.
Normally, the splitter should be bi-directional with a rating of 5 to 1002MHz. Remember to always test them before installation.
In a situation where there are no extra splitters, make use of the two-way splitter and it must be connected to the exact port feeding the modem.
2. Check the frame rate settings
When you notice in failure in synchronization, you need to the settings of the frame rate. Normally, there should be a uniform setting across all the connected devices.
Apart from that, the frame rate settings need to also remain the same on a tape machine, Logic Pro, and synchronizer.
Make sure that MTC did not feed the incorrect frame rates. If you notice the frame rates are wrong, make use of Tempo Editor to manually enter the accurate frame rate settings and as well turn off the detect option.
3. Do not use multiple circular references
The user will also notice a failure in synchronization if the groups are combined using multiple circular references.
You’ll get to see the groups outlined below the response code list. This means the references and settings need to be fixed so you can easily break the cycle.
4. Rename the cloud-managed groups
When the user is still yet to try the overwriting of all the managed groups, it will also affect the synchronization.
This usually happens in a situation where the devices are yet to be renamed. It’s advisable to quickly rename any group that is duplicate to easily eliminate any conflict.
5. Insert a complete response code
When there is a failed transaction, there is every tendency the response code triggers the issue simply because the constraint is already failing.
This is often seen when similar domain names or email address is being used by the user. In other to fix this, put a complete response code.
6. Erase the loaded cloud service
Where the synchronization is not yet enabled on a given account, there is every tendency the cloud might be loaded. In a case like this, restart the directory.
Alternatively, you can restart the synchronization after a given time.
Reach out to your service provider
If you’ve tried all the outlined solutions and yet none worked for you, the next thing is to reach out to the service provider to assist in fixing this issue.
Though you need to be patient until your issue will be attended to but it has a huge success rate.
In Conclusion
The best solutions on how to handle the sync timing synchronization issues have been outlined in the write-up.
It covers all major aspects you must be aware of to get your device working again. Your obligation will be to follow the recommended solution to find answers to your problem.
Frequently Asked Questions
What is the implication of sync timing synchronization failed to acquire QPSK QAM symbol timing?
The outcome is that it will result to malfunction in obtaining the QAM/QPSK symbol timing. The user will then experience out-of-spec and high upstream power.
What are the reasons for RCS partial service?
A modem will be in a partial service mode if it’s functioning with any subset of channels in TCS – Transmit Channel Set OR RCS – Receive Channel Set.
This is because the channel will become unstable as a result of the inability to obtain a channel. Furthermore, it might be because of a loss of communication on the channel.
What does lost MDD timeout?
This is a technical term making reference to DOCSIS-based modems. The user will get to see this warning when a signal is absent from the DOCSIS modem.
In addition, the warning will be seen when there is an unsuccessful establishment of the internet connection.
How do I know the modem isn’t working as it should?
The possible signs you can look out for are;
- The inability of the modem to turn ON.
- Difficulty connecting to the internet.
- Incessant drops in internet connection.
- Inconsistent internet speed or the speed will be reduced unlike before.
- Frequently need to reset the modem so it can function well.
How do I confirm my modem settings?
- Go to the configuration page.
- Open your preferred internet browser.
- Enter the IP address. For instance; http://192.168.1.1. You’ll be taken to the configuration page of your modem.
