This article explains how to upgrade or downgrade the firmware on a DOCSIS gateway (such as the SR804n or SR808ac gateways). The steps are the same for upgrading or downgrading.
When new firmware for a product is acquired from the manufacturer, copy the file to the provisioning server (e.g., LaceyTech) and into the proper directory to be acessible to upgrade or downgrade your gateways.
Watch the video.
Before you can install firmware, you must create a DOCSIS config file to use with it. There is no maximum file size for a configuration file, but a 1 Gb file is not unusual.It's time-consuming to create these files from scratch and involves a lot of trial and error. For these reasons, you should clone an existing config file that is known to work.
Note: The examples in the following steps are LaceyTech-specific but the overall workflow will be similar for other systems.
This task is completed.
