Access Point Firmware Recovery

Purpose

To recover an Access Point whereby the management interface can no longer be accessed when in either "Unleashed Mode", Standalone or the AP is simple not functioning as expected and the ability to flash firmware via the controller is not working.

Pre-Requisites:

• Download the latest version of standalone firmware relevant to your access point
• Please ensure you have installed a TFTP server running on your laptop or desktop which has access to the switch, for windows TFTPD32 is recommended and can be found > TFTPD32 Download

Configuring The Control Files

Before you can tell the AP's to manually downgrade there firmware you must first create a file called fwcntrl.rcks and use your favourite text editor to modify the contents.

The contents must contain the following:

• [rcks_fw.main]
• IP address of TFTP Host
• Standalone Firmware File Name
• Size of Standalone Firmware file in Bytes

An example can be seen below, this file must be stored in your root TFTP directory along with the standalone firmware file.

[rcks_fw.main]
192.168.12.222
H320_110.0.0.0.663.bl7
12720124

CLI Commands for AP's NOT running Unleashed 207.x & Later

These commands must be ran on the AP directly via SSH once logged in

• fw set control fwcntrl.rcks
• fw set proto tftp
• fw set host 192.168.12.222 >>>> IP address of TFTP Server
• fw update

Do not interupt the update once the command "fw update" has been entered. Should the update timeout re run the above commands.
