Objective

TFTP stands for Trivial File Transfer Protocol, a simple protocol used for file transfers. Upgrading a router’s firmware using the TFTP method is the only option when a user is not able to access the router’s webpage via a browser and therefore is unable to upgrade its firmware.

The TFTP method can be used as a recovery tool when a router becomes unresponsive as a result of an interruption during a firmware upgrade (e.g. power-cut or disconnected LAN). This is one of the many advantages offered by Siretta’s Quartz Routers.

Solution

Requirements: –

• PC
• LAN cable
• Router
• Firmware (for this guide we used “3.4.1_18-01-18” firmware)

1. Connect the router to the PC LAN port using the ethernet cable
2. Click the “window icon” from your PC to explore the Menu.
3. Select “Settings” from the start Menu.
4. Choose “Network & internet” from the “Settings” Menu.
5. Select “Ethernet” (See below).

6. Once you have selected “Ethernet” you will be presented with the screen below:

7. Click “Change adaptor option” under “Related Settings” options.
8. Once you have clicked “Change adaptor option” you will be presented with the page below.

9. Double click Ethernet.

10. Double Click “Internet Protocol Version 4 (TCP/IPv4)”.
11. Check and use:
• User “IP address”: 192.168.1.2
• “Subnet Mask”:255.255.255.0
• Leave “Default Gateway” field blank.
• Leave “DNS server addresses” fields blank.
12. Click OK (See below).

13. Connect the router to a PC using the Ethernet cable.
14. Power ON the router / Apply power source.
15. Open the Command window by typing “cmd” in the search bar. (see below).

16. Select “Run as administrator”
17. Click “Yes” when the window notification appears.

18. Command window will open (See below).

19. Issue a “Ping” Command using the following “IP address 192.168.1.1” (See below).

Note: If the Ping request times out, the router webpage (GUI) cannot be accessed for normal firmware upgrades. Double check the LAN cable to ensure it is connected properly, and not damaged, then continue.

20. Unplug the “power source” from the router.
21. Press the “RESET” button of the router and hold.
22. Plug the “power source” in whilst holding the “RESET” button.
23. Wait for about 15 seconds while holding down the “RESET” button.
24. Release the “RESET” button.
25. “Ping” the router again using continuous ping as “Ping 192.168.1.1 -t”.
26. If The “Ping” responses from the router are as seen below, then continue to the next step, otherwise contact Siretta.

27. The results above show that the router can be recovered.
28. Unplug the “power source” from the router.
29. Close the “Command window” tab.
30. Create a folder in C drive called “TFTP”.
31. Download the “TFTP tool” from http://tftpd32.jounin.net/tftpd32_download.html
32. Save the “TFTP tool” in a “TFTP folder”.
33. Copy the “router firmware” (for the router in this example this is Quartz_W22_UMTS_4.3.4.1_18-01-18.trx) to the “TFTP folder”.
34. Open the “exe” from the “TFTP folder”.
35. Select the current directory of the “TFTP”.
36. Select “0.0.1” from the “server Interfaces” drop down menu. See below.

37. Click the “Settings” tab. See below.

48. Enter “Size of pool” as “200”
49. Leave “Lease” as the default value “2880”
50. Copy the “Boot File” name from the “TFTP folder” (In our example this is Quartz_W22_UMTS_4.3.4.1_18-01-18.trx
51. Enter Def. Router (Opt 3) as “192.168.1.4”
52. Enter (Mask Opt 1) as “255.255.255.0”
53. Uncheck “Ping address before assignation”.
54. Uncheck “Persistent leases”
55. See below.

56. Click “OK”.
57. Unplug the “power source” from the router.
58. Press the “RESET” button of the router and hold.
59. Plug the “power source” while holding the reset button.
60. Wait for about 15 seconds while holding down the “RESET” button.
61. Release the “RESET” button.
