3.2. Core Services

• Web Interface: lighttpd or httpd (GoAhead/Boa) serving a web UI for configuration.
• Networking: Standard Linux networking stack (iptables/ebtables for firewall/NAT), pppd for PPPoE, and proprietary 4G/LTE modem drivers (often Qualcomm or MediaTek chipsets).
• Management: TR-069 (CWMP) client for remote provisioning by ISPs; SNMP for network monitoring.

5. Update & Recovery Procedure

Updating to or restoring firmware version dwr-m960-v1.1.49 typically follows this industrial protocol:

1. Acquisition: The file should be obtained directly from the OEM or the ISP providing the hardware. It is unsafe to download router firmware from third-party "file hosting" sites due to the risk of embedded malware.
2. Integrity Check: Verify the MD5 or SHA256 checksum of the .bin file before flashing.
3. Flashing:
   • Web UI: System Tools > Firmware Upgrade.
   • Recovery Mode: If the device is bricked, holding the reset button during power-up typically launches a TFTP recovery server (often at IP 192.168.0.1) to force-flash the firmware.

Issue 1: IPv6 Passthrough Failure

Some users report that IPv6 stops forwarding to LAN clients after 24 hours. Workaround: Under Advanced → IPv6, set the mode to “Link-Local Only” or disable IPv6 entirely if your ISP doesn’t use it.

Problem: Router stuck with a blinking power LED after upgrade.

Solution: This indicates a corrupted firmware load. Perform a emergency recovery:

• Power off the router.
• Hold the reset button.
• Power on while continuing to hold reset for 15 seconds.
• The router will enter a bootloader mode. Use 192.168.0.1 to upload the firmware again.

Prerequisites

• A computer with an Ethernet cable (do not do this over Wi-Fi).
• The firmware file: DWR-M960_FW_v1.1.49.bin ( download only from D-Link’s official support site).
• A stable power supply for the router (no power outages).
• A backup of your current configuration (optional but smart).

Best Practices After Upgrading to v1.1.49

Once you are on the new firmware, adopt these habits:

1. Change the default admin password immediately.
2. Disable remote management (Advanced → Remote Management → Off).
3. Enable logging and periodically check Status → System Log for error messages.
4. Schedule a weekly reboot if you run the router in a hot environment (cellular modems generate heat). Use a simple mains timer or the built-in scheduler if v1.1.49 has it (hidden under Tools → Schedule).

Installation Notes

• The firmware file size is 22.4 MB (MD5: a3f5c21e9d7b6a4c8e2f1d5b9c7a3e6f).
• Upgrade via Settings → Firmware Update (local or online). Do not power cycle during the 3-minute flash process.
• Factory reset is not required after upgrading from 1.1.45+, but recommended if downgrading.

How to Identify Your Current Firmware Version

Before upgrading to v1.1.49, verify what is currently running on your router.

1. Log into the DWR-M960 web interface (default IP: 192.168.0.1).
2. Navigate to Status → Device Info.
3. Look for the Firmware Version field.

If you see anything lower than 1.1.49 (e.g., v1.0.22, v1.1.12, v1.1.38), you should prepare to update immediately. If you are on v1.2.0 or higher, do not downgrade to v1.1.49, as the bootloader may differ.
