TD-W8961N V4 - Settings Reset After Power Cycle & Infinite Reboot Loop
The Problem
I am experiencing a critical issue where my modem loses all configuration settings every time it is powered off or if there is a power outage. Instead of reconnecting, the device requires a full factory reset and manual reconfiguration to access the internet again.
Detailed Symptoms
Whenever the power is cycled, the modem enters a specific reboot loop:
-
DSL LED turns on (syncing).
-
WAN and LAN LEDs suddenly shut off.
-
The DSL LED turns off immediately after.
-
The sequence repeats indefinitely until a manual factory reset is performed.
Troubleshooting Already Performed
-
Isolation Test: I tested my older modem on the same line; it connects instantly and retains settings without any issues. This confirms the problem is specific to the TD-W8961N V4 unit.
-
Consistency: This happens every single time the power is cut.
Request
Is there a firmware update specifically addressing NVRAM (memory) retention for the V4 hardware? Or is this a known hardware defect requiring an RMA?
Any advice or official firmware links would be greatly appreciated.
