# Disable Wifi When Connected via Ethernet Using SSH

### Introduction

The **WiFi module** of your Lattice is active at all times by default, even when connected via Ethernet. If you will be using your Lattice1 with cable connection only and don't want the device to emit additional RF radiation, you can manually disable the WiFi module **through SSH**.

{% hint style="danger" %}
Please make 100% sure you are **connected via Ethernet** first as the only way to revert this if you can't communicate with the Lattice1 through cable is by **resetting the device's router**.
{% endhint %}

Turning the WiFi module off requires you to **SSH into your Lattice1** - if you're new to this, here's a guide:

### Step-by-Step Guide

1. **SSH** into your Lattice1.&#x20;
2. Type in the following **commands**:
   1. `uci set wireless.radio0.disabled='1'`&#x20;
   2. `uci commit wireless`&#x20;
   3. `wifi`
3. **Done!**
4. If you want to turn the **WiFi back on** in the future, you will use the same commands (just set the wireless.radio0.disabled bool back to '0'):
   1. `uci set wireless.radio0.disabled='0'`&#x20;
   2. `uci commit wireless`&#x20;
   3. `wifi`
