---

Common Default Login Credentials

Username	Password
admin	Syro@43210$
root	Syro@43210$
admin	admin (older firmware)
admin	stdONUioi (specific ONT models)

⚠ Credentials vary by:

• Firmware version

• Hardware version

• Device type

---

Technical Explanation

Why IP & Credentials Matter

Default access details are required for:

✔ Firmware upgrades
✔ Configuration backup
✔ Diagnostics
✔ Recovery operations

Failure scenarios:

• Cannot access Web UI

• Upgrade impossible

• Recovery blocked

---

Step 1 — Identify Device Information

Login via browser:

http://192.168.1.1

OR

http://192.168.8.100

Collect:

• Model number

• Hardware version

• Firmware version

Typical menu:

Status → Device Information

CLI (if available):

show version

---

Step 2 — Firmware Selection Rules

Firmware must match:

✔ Exact Model
✔ Exact Hardware Version

Example:

Model: SY-GPON-1010-WDONT
HW Version: 2.4F
Firmware: HW 2.4F ONLY

Mismatch results:

• Invalid firmware error

• Boot failure

• Device brick

---

Step 3 — Firmware Download & Validation

Best practices:

✔ Stable connection
✔ Complete download
✔ Verify checksum

Checksum example:

CertUtil -hashfile firmware.bin SHA256

---

Firmware Upgrade Workflow

Pre-Upgrade Checklist

✔ Backup configuration
✔ Ensure power stability
✔ Use wired LAN
✔ Verify firmware compatibility

Backup path:

System → Backup / Restore

---

Upgrade via Web Interface

System → Firmware Upgrade → Upload File

⚠ Do NOT interrupt power

---

Upgrade via CLI (If Supported)

copy tftp flash
reload

Example:

copy tftp://192.168.1.10/fw.bin flash:

Common Access Issues & Fixes

---

Static IP Troubleshooting

If Web UI inaccessible:

Assign manual IP:

IP: 192.168.1.10
Mask: 255.255.255.0
Gateway: 192.168.1.1

---

Firmware Recovery Scenarios

Emergency Recovery (Generic)

1. Assign PC IP: 192.168.1.10
2. Start TFTP Server
3. Boot device in recovery mode
4. Push firmware image

---

Security Considerations

Default Credential Risk

⚠ Major security vulnerability

Mandatory action:

System → Account → Change Password

---

Firmware Integrity Risk

✔ Use vendor firmware only
✔ Avoid modified firmware
✔ Validate checksums

---

Best Practices

✔ Always backup config
✔ Validate hardware version
✔ Upgrade during maintenance window
✔ Maintain firmware archive
✔ Document provisioning settings

---

Conclusion

Default IP & credentials are essential for:

✔ Device management
✔ Firmware upgrades
✔ Diagnostics & recovery

Failure to secure defaults leads to:

⚠ Unauthorized access
⚠ Network compromise
⚠ ISP security incidents
