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:

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!
