Changing the FortiWiFi firmware
36
Note: Installing firmware replaces the current antivirus and attack definitions with the definitions
included with the firmware release that you are installing. After you install new firmware, use the
procedure "To update antivirus and attack definitions" on page 127
and attack definitions are up to date. You can also use the CLI command
update_now to update the antivirus and attack definitions.
To use the following procedure you must have a TFTP server that the FortiWiFi unit
can connect to.
To revert to a previous firmware version using the CLI
1 Make sure that the TFTP server is running.
2 Copy the firmware image file to the root directory of the TFTP server.
3 Log into the FortiWiFi CLI.
Note: To use this procedure you must login using the admin administrator account, or an
administrator account that has system configuration read and write privileges.
4 Make sure the FortiWiFi unit can connect to the TFTP server.
You can use the following command to ping the computer running the TFTP server.
For example, if the TFTP server's IP address is 192.168.1.168:
execute ping 192.168.1.168
5 Enter the following command to copy the firmware image from the TFTP server to the
FortiWiFi unit:
execute restore image <name_str> <tftp_ipv4>
Where <name_str> is the name of the firmware image file and <tftp_ip> is the IP
address of the TFTP server. For example, if the firmware image file name is
FGT_300-v280-build158-FORTINET.out and the IP address of the TFTP server
is 192.168.1.168, enter:
execute restore image FGT_300-v280-build158-FORTINET.out
192.168.1.168
The FortiWiFi unit responds with the message:
This operation will replace the current firmware version!
Do you want to continue? (y/n)
6 Type y.
The FortiWiFi unit uploads the firmware image file. After the file uploads, a message
similar to the following is displayed:
Get image from tftp server OK.
Check image OK.
This operation will downgrade the current firmware version!
Do you want to continue? (y/n)
7 Type y.
The FortiWiFi unit reverts to the old firmware version, resets the configuration to
factory defaults, and restarts. This process takes a few minutes.
8 Reconnect to the CLI.
