8 Firmware Upgrade
8.1 Upgrading from to a new 8.2 firmware version using http
Please note that the correct file format for web based firmware
upgrade should be ‘.tar’. If the upgrade file you have is ‘.bin’ format
then this is NOT the correct format to upgrade using the web
interface. Upgrade using ‘.bin’ files can only be done using the
xmodem method given in the next section.
Assuming you have the correct firmware file, from the web browser
configuration screen go to the System/Upgrade menu option:
Click on Browse to select the firmware file (please note of the file
was supplied zipped then you must first unzip the file before use).
Then Click on Upgrade and wait. Firmware upgrade should only
take a few minutes. During this period do not touch the router or
browser –
leave them alone until the upgrade file is loaded.
After the flash update is complete the following screen should
display.
You should now restart.
8.1.1 When things go wrong!
If something goes wrong with the firmware upload which causes
only part of the firmware to install then you will need to connect to
the console port of the router via the serial port of your computer
using terminal software (e.g. Windows Hyperterminal); use serial
port settings of 9600bps, 8 data, 1 stop, no parity, none flow control
(details are given above on how to enter console mode).
If the prompt on the console screen is either ‘]’ or the word ‘DEBUG’
or ‘DSL>’ or the MAC address of the router then the firmware’s
corrupted (the correct prompt should be “Login”). In which case you
will have to manually reload the firmware files.
In this case you will have to use the ‘xmodem’ technique to reload
both the bootcode and main firmware files. Please refer to the next
section on how to do this.
