Model: Archer AX12 v1.0 Current Firmware: 1.2.1 Build 20250729 Rel. 73566(4555)

Issue Description: Hello. I bought this router 2 days ago. I am experiencing constant network drops and router service restarts every 30–60 minutes. The internet LED goes off, then the router reconnects.

System Log Evidence: Every time the connection drops, the System Log shows these specific errors indicating an internal failure:

Troubleshooting steps I have ALREADY tried (Please read carefully):

1. Power Stability: Connected the router to a Battery Power Station (Bluetti) working in battery mode (Pure Sine Wave) to rule out AC grid fluctuations. The issue persists even on pure battery power.

2. Resets: Performed both Soft Reset (via Web UI) and Hard Reset (holding the physical button for 20 seconds).

3. Cables: ISP cable is tested and stable directly to PC.

Downgrade Attempt: I tried to downgrade to firmware 1.1.28 Build 20250523, but the router throws an error (likely due to anti-rollback protection in version 1.2.1).

Question: Is this a known bug in Firmware 1.2.1? Is there a Beta firmware to fix the Config importing failed loop? Or is this a hardware defect of the flash memory?

Attachments: I have attached the full System Log file (syslog.txt) and a screenshot of my current firmware version for your reference.
