Have the new software ready and know the location of the file. Make sure you have TFTP command file
in your system.
1. If you don't have TFTP DOS software version, please download it first.
2. Make sure your PC has an Ethernet connection to the DSL LAN Extender device.
3. Start a MS-DOS session from your PC.
4. Navigate to the folder where you have the new software located.
5. Enter the following DOS command, assuming the device's IP address is 10.0.0.1 and the file you
want to upgrade is wcgr1001.21s: tftp -i 10.0.0.1 put wcgr1001.21s
6. Now check the progress and see if the download is successful. Soon after you entered the TFTP
command, the LEDs will be flashing cyclically, indicating that it has accepted the downloading
command and is processing it. Typically, it takes 50 to 60 seconds to finish the upgrade, and the
DSL LAN Extender device will automatically reboot and start operation immediately.
7. The success of the download can also be seen from the result of the TFTP command, showing the
command executed successfully and actual time it took. If, on the other hand, the TFTP was
finished with a "timeout occurred" message, and you need to find out why.
8. If the LEDs on the DSL LAN Extender device display a normal pattern after you entered the
TFTP command, then either the PC doesn't have a good Ethernet connection to the device or the
IP address you entered is incorrect.
9. If the LEDs kept circulating, then the download has failed in the middle. You have to reboot the
device by powering off and on. If the problem occurred at the earlier stage and the flash ROM has
not been overwritten, then the device will boot as usual; otherwise, both red and green LEDs will
be on steadily, indicating it can't perform a normal boot up and is only waiting for a download.
10. Now, try to perform the upgrade again.
