Archer C64 Freezes and Goes Offline After Updating to Firmware 1.14.3
Hello,
After updating to the latest firmware, my Archer C64 started freezing, and I can no longer connect to it either online or within the local network.
The only solution that works is a physical reboot. The issue occurs every 1-2 hours.
I have a main router and two secondary ones set up with EasyMesh. Before the update, everything was working perfectly.
Unfortunately, I cannot seem to downgrade to the previous firmware version (e.g., Archer C64(EU)_V1_1.13.15 Build 240812) from:
https://www.tp-link.com/en/support/download/archer-c64/#Firmware
In the logs, I see the following entries:
158 INFO 0days, 00:11:21, [upgrade]start upgrade
159 ERROR 0days, 00:11:21, [upgrade]SID not match, 0x5545:0x5355

170 ERROR 0days, 00:11:21, [upgrade]main version 0x10d00 is smaller than 0x10e00!
Considering that resolving this issue might take time, I kindly ask you to provide instructions on how to downgrade to the previous firmware version.
These problems have rendered my device almost unusable, and I urgently need a solution.
Thank you!

As I mentioned earlier, the device freezes when the UART console endlessly outputs "[mt7626]kick out msg fail".
This indicates that the device is stuck in an infinite loop.
I can assume that during this time, the CPU is at 100% utilization, which causes the entire device to overheat — something it wasn’t designed to handle.
Now imagine what might happen if the router is left unattended or not rebooted for a few days in this state.
How did I figure out the issue is related to RTMP?
It was straightforward — I searched for the error message the router provided via UART on GitHub.
The search returned 83 results, all of them tied to RTMP on various devices.
Here are a few examples:
These findings strongly suggest that the issue is tied to how RTMP is handled on this firmware version.

The support engineer has offered you a beta firmware via email, have you found it? It's suggested to update the beta firmware and monitor if the issue can be fixed.

@Kevin_Z
Thank you for your response. I’ve installed the beta version and will monitor the issue. I’ll report the results once I have more information.

@Kevin_Z After installing the beta version 1.14.3 Build 241128 Rel.61573n(4555), the router has not frozen so far.

@tapac3 Hello, the same error also occurs with my C64, but I really don't understand the technical details about it so I cannot provide any insight. If beta FW is working for you, could you provide it to me please?

@Alt_Bird Hi. From what I understand, the issue might be related to RTMP.
Keep in mind that I have the physical version V1 (EU) of the router.
If you have the same version, try installing the beta firmware and leave your feedback here to let us know if the issue gets resolved.

@tapac3 Yes, I also have the V1 EU version. I installed the beta firmware and will update you after a while. Thanks.

@tapac3 After a day of normal use, there has not been any problems. Seems like this beta FW fixes the problem.

After testing the beta version 1.14.3 Build 241128 Rel.61573n(4555) for several days, the device has stopped freezing.
Now the question remains: when can we expect a stable, non-beta version of the firmware to be released?

Thank you very much for your valuable feedback.
This issue will be addressed in future official firmware releases, but I cannot provide an exact EAT. It's suggested to pay close attention to the new firmware releases on your router web GUI and the Tether App.
BTW, do you enable Access Control on the C64?
How about you? @Alt_Bird Do you use Access Control on your C64?
