Phenomenon Description:

We've received users' feedback that the Archer C80 V2.20/C64 V1 may freeze intermittently after updating the firmware to 1.14.0/1.14.3. This issue occurs when the Access Control feature is enabled while setting up a mesh network, causing the device to become unstable and, in some cases, freeze after a short period of operation.
