# auto-update days

Set the day(s) of the week to perform automatic updates of the system firmware

## Syntax

```
auto-update days all|none|<day> [<day> [...]]
```

<table><thead><tr><th width="203">Keyword</th><th>Description</th></tr></thead><tbody><tr><td><code>all</code></td><td>Specifies that updates may occur on any day of the week.

Must be one of <code>monday</code>, <code>tuesday</code>, <code>wednesday</code>, <code>thursday</code>, <code>friday</code>, <code>saturday</code>, or <code>sunday</code>. Multiple days may be specified separated by spaces. Mutually exclusive with <code>all</code> and <code>none</code>.</td></tr><tr><td></td><td></td></tr></tbody></table>

## 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 ](/island-router-cli-2.3.2/commands/update.md)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

```
auto-update days thursday friday
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.islandrouter.com/island-router-cli-2.3.2/commands/auto-update/auto-update-days.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
