## Defaults

Updates will be performed at 3:00 AM local time on any day of the week by default.

## Usage Guidelines

The Island periodically checks to see if newer firmware is available. This command sets the day(s) of the week on which new firmware is allowed to be automatically installed.

If automatic updates are disabled using the command `auto-update days none`, the Island will still periodically check for firmware updates, and the app will indicate that newer firmware is available, but it will not be installed automatically. In this case, the user can install the update using the [update ](https://docs.islandrouter.com/island-router-cli-2.3.2/commands/update)command or the Island app.

Firmware updates may or may not interrupt packet routing, depending on the nature and extent of the update. Some updates will not interrupt routing at all, some may cause a short (5-10 second) interuption, and some may require a full reboot of the router.

## Examples
