Step 1: Backup Your Configuration
Navigate to Management > Settings > Backup. Save the .cfg file. Note: It is often safer NOT to restore old configs after a major firmware upgrade (e.g., v2.x to v4.x), as the data structure changes.
Step 2: Hard Reset (Optional but Recommended) Press the physical reset button on the back for 10 seconds. This clears the NVRAM, preventing conflicts.
Step 3: Access the Firmware Upgrade Page
Step 4: Upload the File

In the world of industrial and prosumer networking, the D-Link DWR-M960 stands out as a rugged 4G LTE router designed for M2M (Machine to Machine) communication, remote monitoring, and failover solutions. However, like any complex piece of hardware, its performance and security rely entirely on one critical component: the DWR-M960 A2 firmware. dwr-m960 a2 firmware
If you have landed on this page, you are likely searching for a solution to a connectivity drop, a security vulnerability, or a new feature update. This 2,000-word guide will walk you through everything you need to know about finding, verifying, installing, and troubleshooting the DWR-M960 A2 firmware.
Disclaimer: Updating firmware carries an inherent risk. If interrupted (power loss), it can permanently brick your device. Proceed at your own risk. This guide is for educational purposes. Always verify your hardware revision before proceeding.
Newer firmware (>v3.00) includes a hidden cron job. Go to System > Scheduler to set the router to reboot weekly at 3:00 AM. This clears the modem’s RAM and prevents memory leaks. Step 1: Backup Your Configuration Navigate to Management
The A2 firmware is a proprietary Linux-based operating system with the following partition layout:
| Partition | Size | Content | Volatile |
| :--- | :--- | :--- | :--- |
| uboot | 512 KB | Custom U-Boot (A2-specific DDR init) | No |
| uboot-env | 128 KB | Boot environment variables | No |
| firmware | ~28 MB | SquashFS + kernel + rootfs | No |
| firmware2 | ~28 MB | Failover/backup firmware | No |
| art | 256 KB | Wi-Fi calibration (A2-specific) | No |
| lte_data | 64 MB | Modem firmware & carrier profiles | Semi (upgradeable) |
| log | 8 MB | System logs | Yes |
| Symptom | Likely Cause | A2-Specific Fix |
| :--- | :--- | :--- |
| LTE connected but no internet | APN mismatch after OTA update | Factory reset from bootloader (not UI) → re-enter APN manually |
| 5 GHz Wi-Fi disappears after reboot | ART partition corruption (A2 known defect) | Re-flash art_a2_backup.bin via serial console |
| "Firmware upgrade failed" at 99% | NAND bad block (A2 batch: 2023-24) | Use force option via SSH: sysupgrade -n -F |
| Router boot loops every 3 minutes | Corrupt lte_data from power loss | Serial interrupt → setenv bootargs lte_skip → boot, then reflash modem firmware | Step 4: Upload the File
