# Settings

The **Settings** page allows you to specify the CPE Antenna Gain, select the APN of the Mesh Backhaul, and change the Wi‑Fi password and the LCI password. The current settings of the CPE Antenna Gain, and the Mesh Backhaul APN are displayed when the **Settings** page is opened.

## Set the CPE Antenna Gain

It is the responsibility of the installer to confirm that the value in the **CPE Antenna Gain** field matches the actual gain of the CPE antenna that is being used for the backhaul. The GM02 will reduce the transmit power to the antenna based on this setting.

**To enter the antenna gain:**

{% stepper %}
{% step %}
Click the **Settings** link at the top right side of any of the Mesh Node’s webpages to open the **Settings** page.
{% endstep %}

{% step %}
Enter the correct gain value in the **CPE Antenna Gain** field. (The default value is 20dB.)
{% endstep %}

{% step %}
Click the **Save** button.

{% hint style="warning" %}
**CAUTION:** It is the installer’s responsibility to ensure that the value entered for the CPE Antenna Gain accurately represents the actual gain of the backhaul antenna.
{% endhint %}
{% endstep %}
{% endstepper %}

## Enter the MeshBackhaul APN

The APN for a GM02 Mesh Node SIM is “MeshBackhaul”. The APN is case-sensitive with an uppercase “M” and “B” and all other letters lowercase. This APN must match the “MeshBackhaul” APN specified in the Onyx Portal in order for the Mesh Node to connect to the Onyx Portal.

{% stepper %}
{% step %}
Click the **Settings** link at the top right side of any of the Mesh Node’s webpages to open the **Settings** page.
{% endstep %}

{% step %}
Enter “MeshBackhaul” in the **Mesh Backhaul APN** field.
{% endstep %}

{% step %}
Click the **Save** button.
{% endstep %}
{% endstepper %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.gxc.io/hw/lte/4g-mesh-nodes/gm02/gm02-mesh-node-installation-guide/settings.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.
